Obsessive-compulsive personality disorder US Medical PG Question 1: A 24-year-old man presents to the college campus clinic worried that he is having a nervous breakdown. The patient was diagnosed with attention-deficit/hyperactivity disorder (ADHD) during his freshman year and has been struggling to keep his grades up. He has recently become increasingly worried that he might not be able to graduate on time. For the past 2 months, he has been preoccupied with thoughts of his dorm room burning down and he finds himself checking all the appliances and outlets over and over even though he knows he already checked everything thoroughly. This repetitive behavior makes him late to class and has seriously upset his social activities. The patient is afebrile and vital signs are within normal limits. Physical examination is unremarkable. Which of the following is the most likely diagnosis?
- A. Obsessive-compulsive disorder (Correct Answer)
- B. Tourette syndrome
- C. Delusional disorder
- D. Schizophrenia
- E. Obsessive-compulsive personality disorder
Obsessive-compulsive personality disorder Explanation: ***Obsessive-compulsive disorder***
- The patient exhibits **recurrent, persistent thoughts (obsessions)** about his dorm room burning down and **repetitive behaviors (compulsions)** of checking appliances, which are characteristic of OCD.
- These obsessions and compulsions cause **significant distress** and **impairment** in his social activities and academic life, meeting the diagnostic criteria for OCD.
*Tourette syndrome*
- This condition is primarily characterized by **multiple motor tics** and **one or more vocal tics**, which fluctuate over time.
- While tics can be severe and impairing, they are distinct from the **obsessive thoughts** and **compulsive checking behaviors** described in the patient.
*Delusional disorder*
- Delusional disorder involves the presence of **non-bizarre delusions** (beliefs that are not obviously implausible) for at least one month, without other significant psychotic symptoms.
- The patient's preoccupation with his dorm room burning down, while intense, is recognized by him as excessive ("he knows he already checked everything thoroughly"), indicating it is an obsession rather than a **firmly held false belief (delusion)**.
*Schizophrenia*
- Schizophrenia is characterized by a combination of positive symptoms (e.g., **hallucinations, delusions, disorganized speech**), negative symptoms (e.g., **alogia, avolition**), and cognitive dysfunction.
- The patient's symptoms are specific to obsessions and compulsions, without the broader range of **psychotic symptoms** or **functional decline** typically seen in schizophrenia.
*Obsessive-compulsive personality disorder*
- OCPD is a pervasive pattern of preoccupation with **orderliness, perfectionism**, and **mental and interpersonal control** at the expense of flexibility, openness, and efficiency.
- Unlike OCD, OCPD does not involve true **obsessions** or **compulsions** and is considered ego-syntonic, meaning the individual perceives their traits as desirable, whereas the patient is distressed by his checking behavior.
Obsessive-compulsive personality disorder US Medical PG Question 2: A 19-year-old woman comes to the physician because of a 2-day history of difficulty sleeping. She worries that the lack of sleep will ruin her career prospects as a model. She has been coming to the physician multiple times over the past year for minor problems. She is dressed very extravagantly and flirts with the receptionist. When she is asked to sit down in the waiting room, she begins to cry and says that no one listens to her. When she is called to the examination room, she moves close to the physician, repeatedly intends to touch his cheek, and makes inappropriate comments. She does not have a history of self-harm or suicidal ideation. Which of the following is the most likely diagnosis?
- A. Schizotypal personality disorder
- B. Borderline personality disorder
- C. Dependent personality disorder
- D. Narcissistic personality disorder
- E. Histrionic personality disorder (Correct Answer)
Obsessive-compulsive personality disorder Explanation: ***Histrionic personality disorder***
- This patient displays classic features of **histrionic personality disorder**, including **attention-seeking behaviors** (flirting, extravagant dress, dramatic crying), **inappropriate sexually seductive behavior** toward the physician, and **rapidly shifting and shallow emotions** (cries that no one listens to her, then attempts to touch the physician).
- Her excessive emotionality and constant need to be the center of attention, coupled with a tendency to use physical appearance to draw attention to herself, align well with the diagnostic criteria.
*Schizotypal personality disorder*
- Characterized by a pervasive pattern of **social and interpersonal deficits** marked by acute discomfort with, and reduced capacity for, close relationships, as well as by **cognitive or perceptual distortions** and eccentricities of behavior.
- This patient does not exhibit evidence of odd beliefs, magical thinking, unusual perceptual experiences, or paranoid ideation typical of schizotypal personality disorder.
*Borderline personality disorder*
- Marked by a pervasive pattern of **instability of interpersonal relationships, self-image, and affects**, and marked impulsivity. Patients often exhibit intense fears of abandonment, chronic feelings of emptiness, and self-harming behaviors.
- While there is some emotional dysregulation and intense relationships, the patient does not report **self-harm, suicidal ideation**, or the severe identity disturbance common in borderline personality disorder.
*Dependent personality disorder*
- Individuals with dependent personality disorder exhibit an excessive need to be cared for, leading to **submissive and clinging behavior** and fears of separation. They often have difficulty making everyday decisions without excessive reassurance.
- This patient's behaviors are geared towards attracting attention and being the center of it, rather than seeking reassurance or exhibiting submissive behavior.
*Narcissistic personality disorder*
- Characterized by a pervasive pattern of **grandiosity, a need for admiration**, and a lack of empathy. Patients often believe they are special and unique and expect to be recognized as superior.
- While this patient seeks attention, her behavior is more about being dramatic and emotionally expressive rather than a sense of inflated self-importance or a deep need for admiration stemming from grandiosity.
Obsessive-compulsive personality disorder US Medical PG Question 3: A 28-year-old woman is brought to a counselor by her father after he found out that she is being physically abused by her husband. The father reports that she refuses to end the relationship with her husband despite the physical abuse. She says that she feels uneasy when her husband is not around. She adds, “I'm worried that if I leave him, my life will only get worse.” She has never been employed since they got married because she is convinced that nobody would hire her. Her husband takes care of most household errands and pays all of the bills. Physical examination shows several bruises on the thighs and back. Which of the following is the most likely diagnosis?
- A. Schizoid personality disorder
- B. Separation anxiety disorder
- C. Avoidant personality disorder
- D. Dependent personality disorder (Correct Answer)
- E. Borderline personality disorder
Obsessive-compulsive personality disorder Explanation: ***Dependent personality disorder***
- This patient exhibits a pervasive and excessive need to be taken care of, leading to **submissive and clinging behavior, and fears of separation**. Key features include difficulties making decisions, avoiding disagreement due to fear of loss of support, and preoccupation with fears of being left to care for herself.
- Her comments about her life getting worse if she leaves her husband, her inability to seek employment, and her husband managing all household affairs are consistent with her **reluctance to leave an abusive relationship** because of an exaggerated fear of being alone or unable to care for herself.
*Schizoid personality disorder*
- Characterized by a pervasive pattern of **detachment from social relationships** and a restricted range of emotional expression.
- Individuals with this disorder typically show **little interest in forming close relationships**, in contrast to the patient's clinging behavior.
*Separation anxiety disorder*
- Primarily marked by **excessive anxiety concerning separation from home or from those to whom the individual is attached**, often seen in childhood, but can occur in adults.
- While there is some anxiety about separation, the patient's broader pattern of submissive behavior, difficulty with independent functioning, and belief she cannot care for herself points more strongly to a **personality disorder** rather than an anxiety disorder focused solely on separation.
*Avoidant personality disorder*
- Involves extreme social inhibition, feelings of inadequacy, and **hypersensitivity to negative evaluation**.
- These individuals **desire social connection but avoid it due to fear of rejection**, which contrasts with the patient's clinging and submissive efforts to maintain a relationship.
*Borderline personality disorder*
- Characterized by significant **instability in moods, interpersonal relationships, self-image, and behaviors**.
- While there can be fear of abandonment, this disorder typically involves **impulsivity, intense anger, and frantic efforts to avoid abandonment**, which are not the primary features described in this patient.
Obsessive-compulsive personality disorder US Medical PG Question 4: A 25-year-old male medical student presents to student health with a chief complaint of picking at his skin. He states that at times he has urges to pick his skin that he struggles to suppress. Typically, he will participate in the act during finals or when he has "too many assignments to do." The patient states that he knows that his behavior is not helping his situation and is causing him harm; however, he has trouble stopping. He will often ruminate over all his responsibilities which make his symptoms even worse. The patient has a past medical history of surgical repair of his ACL two years ago. His current medications include melatonin. On physical exam you note a healthy young man with scars on his arms and face. His neurological exam is within normal limits. Which of the following is the best initial step in management?
- A. Fluoxetine (Correct Answer)
- B. Dialectical behavioral therapy
- C. Interpersonal psychotherapy
- D. Clomipramine
- E. Supportive psychotherapy
Obsessive-compulsive personality disorder Explanation: ***Fluoxetine***
- This patient's symptoms are consistent with **excoriation (skin-picking) disorder**, characterized by recurrent skin picking resulting in lesions and significant distress or impairment, often triggered by stress.
- **First-line treatment** is typically **cognitive-behavioral therapy (CBT)** with habit reversal training; however, among the options provided, **selective serotonin reuptake inhibitors (SSRIs)** like fluoxetine represent the most evidence-based pharmacological approach.
- **SSRIs** are considered when psychotherapy is unavailable or as adjunctive treatment for excoriation disorder and comorbid anxiety/OCD symptoms, though evidence is mixed.
- Fluoxetine is the best option listed for initial management in this clinical scenario.
*Dialectical behavioral therapy*
- **Dialectical behavioral therapy (DBT)** is primarily used for **borderline personality disorder** and chronic suicidality, focusing on emotion regulation and distress tolerance.
- While some of its techniques could be broadly helpful, it is not the primary or most effective treatment for excoriation disorder specifically.
- **CBT with habit reversal training** would be preferred over DBT for this condition.
*Interpersonal psychotherapy*
- **Interpersonal psychotherapy (IPT)** is an evidence-based treatment mainly for **depression** and some eating disorders, focusing on improving interpersonal relationships and social functioning.
- It does not directly target the compulsive behaviors or urge suppression central to excoriation disorder.
*Clomipramine*
- **Clomipramine**, a tricyclic antidepressant (TCA), is effective for **obsessive-compulsive disorder (OCD)**, but it has a less favorable side effect profile than SSRIs.
- Due to its side effects and lower tolerability, it is usually reserved for cases resistant to SSRIs, making it not the best initial pharmacologic step.
*Supportive psychotherapy*
- **Supportive psychotherapy** aims to alleviate symptoms, maintain self-esteem, and improve coping skills, offering a general supportive environment.
- While it can be helpful as an adjunct, it lacks the specific behavioral or pharmacological mechanisms needed for effective treatment of excoriation disorder.
Obsessive-compulsive personality disorder US Medical PG Question 5: A 35-year-old woman presents to clinic in emotional distress. She states she has been unhappy for the past couple of months and is having problems with her sleep and appetite. Additionally, she reports significant anxiety regarding thoughts of dirtiness around the house. She states that she cleans all of the doorknobs 5-10 times per day and that, despite her actions, the stress related to cleaning is becoming worse. What is this patient's diagnosis?
- A. Panic Disorder (PD)
- B. Generalized anxiety disorder (GAD)
- C. Obsessive compulsive personality disorder (OCPD)
- D. Obsessive compulsive disorder (OCD) (Correct Answer)
- E. Tic disorder
Obsessive-compulsive personality disorder Explanation: ***Obsessive compulsive disorder (OCD)***
- The patient's **recurrent distressing thoughts** about dirtiness (obsessions) and **repetitive cleaning behaviors** (compulsions) designed to reduce anxiety are hallmark symptoms of OCD.
- The significant **emotional distress**, impact on daily life, and worsening stress despite the compulsions further support this diagnosis.
*Panic Disorder (PD)*
- Characterized by **recurrent, unexpected panic attacks** and persistent worry about additional attacks or their consequences.
- While anxiety is present, the patient's primary distress is driven by specific obsessions and compulsions, not sudden episodes of intense fear.
*Generalized anxiety disorder (GAD)*
- Involves **excessive, uncontrollable worry** about a variety of events or activities for at least 6 months.
- The anxiety symptoms are general, not focused on specific obsessions leading to compulsive behaviors as seen in this case.
*Obsessive compulsive personality disorder (OCPD)*
- Marked by pervasive patterns of **perfectionism, orderliness, and control** at the expense of flexibility and efficiency.
- While there may be a preoccupation with rules, OCPD does not typically involve intrusive, ego-dystonic obsessions or ritualistic compulsions like repetitive cleaning to reduce anxiety.
*Tic disorder*
- Characterized by **sudden, rapid, recurrent, non-rhythmic motor movements or vocalizations**.
- Tics are distinct from the complex, goal-directed, and anxiety-driven compulsive behaviors described by the patient.
Obsessive-compulsive personality disorder US Medical PG Question 6: A 10-year-old boy is brought to the physician by his parents because they are concerned about his “strange behavior”. The parents state that he has always been a lonely kid without many friends, but recently he has been having behavioral problems that seem to be unprovoked and are occurring more frequently. The child throws tantrums for no reason and does not respond to punishment or reward. He also has a “strange obsession” with collecting rocks that he finds on his way to and from school to the point where his room is filled with rocks. He plays alone in his room, lining the rocks up, organizing them by size, shape, or color, and he will randomly bark or make high-pitched noises without provocation. His teachers say he daydreams a lot and is very good at art, being able to recreate his favorite cartoon characters in great detail. On physical assessment, the patient does not make eye contact with the physician but talks incessantly about his rock collection. The child’s grammar and vocabulary seem normal but his speech is slightly labored, and he can’t seem to tell that the physician is not really interested in hearing about his rock collection. Which of the following is the most likely diagnosis?
- A. Autism spectrum disorder (Correct Answer)
- B. Obsessive-compulsive disorder
- C. Tourette’s syndrome
- D. Pick disease
- E. Attention deficit hyperactivity disorder
Obsessive-compulsive personality disorder Explanation: ***Autism spectrum disorder***
- This case presents classic features of **autism spectrum disorder (ASD)**, including **social deficits** (lonely, no friends, no eye contact, lack of awareness of others' interest), **repetitive behaviors and fixated interests** (rock collection, lining them up, organizing), and **stereotyped movements/vocalizations** (random barking, high-pitched noises).
- The child's excellent artistic skills and normal grammar/vocabulary despite other communication difficulties are also consistent with the varying presentations within the **autism spectrum**, which can include areas of exceptional talent alongside core deficits.
*Obsessive-compulsive disorder*
- While the rock collection and organizing might resemble an **obsession/compulsion**, OCD typically involves **intrusive thoughts (obsessions)** causing distress and **repetitive behaviors (compulsions)** performed to alleviate that distress.
- The presented social deficits, communication difficulties, and stereotyped movements are not characteristic of OCD alone.
*Tourette’s syndrome*
- **Tourette's syndrome** is characterized by **multiple motor tics** and **one or more vocal tics**. The barking and high-pitched noises could be tics, but Tourette's does not explain the profound social impairments, repetitive behaviors/interests, and communication difficulties described.
- The global pattern of symptoms points beyond Tourette's.
*Pick disease*
- **Pick disease** is a rare form of **frontotemporal dementia** that primarily affects adults, typically presenting with **personality changes**, **behavioral disinhibition**, and **language difficulties**.
- It is an adult-onset neurodegenerative disorder and would not be diagnosed in a 10-year-old child presenting with developmental differences.
*Attention deficit hyperactivity disorder*
- **ADHD** is characterized by **persistent patterns of inattention** and/or **hyperactivity-impulsivity**. While "daydreaming" could suggest inattention, the core features of social impairment, repetitive behaviors, and specific vocalizations are not typical of ADHD.
- The child's "strange obsession" and social isolation point away from a primary diagnosis of ADHD.
Obsessive-compulsive personality disorder US Medical PG Question 7: A 14-year-old girl presents to the pediatrician for behavior issues. The girl has been having difficulty in school as a result. Every time the girl enters her classroom, she feels the urge to touch every wall before heading to her seat. When asked why she does this, she responds, "I'm not really sure. I just can't stop thinking about it until I have touched each wall." The parents have noticed this behavior occasionally at home but were not concerned. The girl is otherwise healthy, has many friends, eats a balanced diet, does not smoke, and is not sexually active. Her temperature is 98.2°F (36.8°C), blood pressure is 117/74 mmHg, pulse is 80/min, respirations are 15/min, and oxygen saturation is 98% on room air. Physical exam is notable for a healthy young girl. Neurologic exam is unremarkable. There is no observed abnormalities in behavior while the girl is in the office. Which of the following is the most appropriate initial step in management for this patient?
- A. Cognitive behavioral therapy (Correct Answer)
- B. Lorazepam
- C. Risperidone
- D. Clomipramine
- E. Fluoxetine
Obsessive-compulsive personality disorder Explanation: ***Cognitive behavioral therapy***
- This patient exhibits classic symptoms of **obsessive-compulsive disorder (OCD)**, characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions) performed to alleviate anxiety.
- **Exposure and response prevention (ERP)**, a component of cognitive behavioral therapy, is the first-line psychosocial treatment for OCD and has strong evidence for its efficacy in both children and adults.
*Lorazepam*
- **Lorazepam** is a benzodiazepine used for acute anxiety or panic attacks, providing short-term relief.
- It is not a primary treatment for OCD and does not address the underlying obsessive-compulsive cycle; long-term use can lead to dependence.
*Risperidone*
- **Risperidone** is an atypical antipsychotic, primarily used for conditions like schizophrenia, bipolar disorder, or severe behavioral disturbances.
- While sometimes used as an augmentation strategy in refractory OCD, it is not a first-line treatment, especially without prior trials of CBT or SSRIs.
*Clomipramine*
- **Clomipramine** is a tricyclic antidepressant (TCA) with potent serotonin reuptake inhibition, making it effective for OCD.
- However, due to its less favorable side effect profile compared to selective serotonin reuptake inhibitors (SSRIs), it is typically reserved for cases where SSRIs are ineffective.
*Fluoxetine*
- **Fluoxetine** is an SSRI, a first-line pharmacologic treatment for OCD.
- While effective, current guidelines recommend starting with **CBT (specifically ERP)** as the initial treatment for mild to moderate OCD, or combining it with medication for more severe cases.
Obsessive-compulsive personality disorder US Medical PG Question 8: A 20-year-old man comes to the physician because of decreasing academic performance at his college for the past 6 months. He reports a persistent fear of “catching germs” from his fellow students and of contracting a deadly disease. He finds it increasingly difficult to attend classes. He avoids handshakes and close contact with other people. He states that when he tries to think of something else, the fears “keep returning” and that he has to wash himself for at least an hour when he returns home after going outside. Afterwards he cleans the shower and has to apply disinfectant to his body and to the bathroom. He does not drink alcohol. He used to smoke cannabis but stopped one year ago. His vital signs are within normal limits. He appears anxious. On mental status examination, he is oriented to person, place, and time. In addition to starting an SSRI, which of the following is the most appropriate next step in management?
- A. Cognitive-behavioral therapy (Correct Answer)
- B. Psychodynamic psychotherapy
- C. Motivational interviewing
- D. Interpersonal therapy
- E. Group therapy
Obsessive-compulsive personality disorder Explanation: **Cognitive-behavioral therapy**
- **Cognitive-behavioral therapy (CBT)**, specifically **Exposure and Response Prevention (ERP)**, is the most effective psychotherapy for **obsessive-compulsive disorder (OCD)**, which this patient's symptoms strongly suggest.
- CBT helps patients challenge distorted thoughts and gradually expose themselves to feared situations while preventing compulsive rituals, thus breaking the cycle of obsessions and compulsions.
*Psychodynamic psychotherapy*
- This therapy focuses on **unconscious conflicts** and **past experiences** to understand current symptoms.
- While it can be helpful for some mental health conditions, it is generally **less effective** than CBT for the specific, highly ritualized symptoms of OCD.
*Motivational interviewing*
- **Motivational interviewing** is a patient-centered counseling style designed to address **ambivalence about change** and enhance intrinsic motivation.
- It is often used in substance abuse or lifestyle changes, but it does not directly teach coping skills for OCD symptoms or address the underlying thought patterns.
*Interpersonal therapy*
- **Interpersonal therapy (IPT)** focuses on the patient's **current interpersonal relationships** and social functioning.
- While social difficulties can arise from OCD, IPT does not directly target the obsessions and compulsions that are central to the disorder.
*Group therapy*
- **Group therapy** can provide support and a sense of community, but for a severe condition like OCD, **individual therapy** (especially CBT/ERP) is typically recommended first due to the highly individualized nature of obsessions and compulsions.
- It may be a complementary approach, but usually not the most appropriate initial next step given the intensity of the patient's symptoms.
Obsessive-compulsive personality disorder US Medical PG Question 9: A 33-year-old man with documented antisocial personality disorder and substance use disorder is convicted of assault. The defense attorney requests psychiatric testimony that the defendant's personality disorder diminished his capacity to conform his conduct to the law. His history includes multiple prior convictions, repeated lying, failure to sustain employment, lack of remorse, and disregard for others' safety. However, he understood the wrongfulness of his actions and planned the assault in advance. Evaluate the relationship between antisocial personality disorder and criminal responsibility.
- A. Chronic pattern of behavior demonstrates inability to conform conduct to law
- B. Combination of personality disorder and substance use negates criminal responsibility
- C. Comorbid substance use disorder supports insanity defense
- D. Antisocial personality disorder does not meet criteria for insanity defense as patients retain capacity to understand wrongfulness (Correct Answer)
- E. Personality disorders qualify for diminished capacity due to impaired impulse control
Obsessive-compulsive personality disorder Explanation: ***Antisocial personality disorder does not meet criteria for insanity defense as patients retain capacity to understand wrongfulness***
- In forensic psychiatry, individuals with **antisocial personality disorder** are generally considered criminally responsible because they retain the **cognitive capacity** to distinguish right from wrong.
- The legal system distinguishes between a "cannot conform" (e.g., severe psychosis) and a "will not conform" (personality disorder); since the defendant **planned the assault**, he demonstrated **volitional control**.
*Chronic pattern of behavior demonstrates inability to conform conduct to law*
- A history of repeated legal infractions reflects a **choice to disregard social norms** rather than an organic or psychotic inability to process reality.
- Under most legal standards, inclusive of the **M'Naghten Rule**, a repetitive criminal history does not constitute the "mental disease or defect" required for an **insanity defense**.
*Combination of personality disorder and substance use negates criminal responsibility*
- Combined pathology does not equate to a loss of **mens rea** (guilty mind); substance use is often viewed as **voluntary intoxication**, which rarely excuses criminal acts.
- The presence of these disorders does not inherently impair the defendant's **rational understanding** of the wrongfulness of the specific criminal act.
*Comorbid substance use disorder supports insanity defense*
- **Substance use disorders** are specifically excluded from the definition of "mental disease or defect" in the context of the **insanity defense** in many jurisdictions.
- To qualify for insanity, a condition must typically involve a disconnection from reality, whereas substance use is considered a **behavioral choice** with known legal risks.
*Personality disorders qualify for diminished capacity due to impaired impulse control*
- **Diminished capacity** is a specific legal defense that usually requires a severe mental impairment that prevents the formation of **specific intent**, which is not seen here as the defendant **planned the assault**.
- While patients with personality disorders exhibit **impulsivity**, they still possess the foundational **legal sanity** required to be held responsible for premeditated actions.
Obsessive-compulsive personality disorder US Medical PG Question 10: A 26-year-old woman presents requesting cosmetic surgery consultation. She is preoccupied with achieving the 'perfect' appearance, has undergone multiple procedures, and expresses disappointment with each result. She describes herself as special and destined for greatness, becomes enraged when her primary care physician suggested psychiatric evaluation, and states she will report him for 'not understanding her needs.' She expects special treatment in the clinic and becomes irritated when kept waiting. On mental status exam, she shows intact reality testing. Analyze the most likely underlying personality structure.
- A. Histrionic personality disorder with attention-seeking behavior
- B. Obsessive-compulsive personality disorder with perfectionism
- C. Borderline personality disorder with identity disturbance
- D. Narcissistic personality disorder with difficulty tolerating narcissistic injury (Correct Answer)
- E. Body dysmorphic disorder with poor insight
Obsessive-compulsive personality disorder Explanation: ***Narcissistic personality disorder with difficulty tolerating narcissistic injury***
- The patient exhibits core features of **Narcissistic Personality Disorder (NPD)**, including a **grandiose sense of self-importance**, beliefs of being "special," and an extreme **sense of entitlement** regarding special treatment in the clinic.
- Her enraged reaction to the suggestion of a psychiatric evaluation is a classic example of **narcissistic rage**, which occurs after a **narcissistic injury** (a threat to one's inflated self-image or perceived perfection).
*Histrionic personality disorder with attention-seeking behavior*
- While both can involve vanity, histrionic patients are typically **emotionally labile** and seek any kind of attention, rather than specifically requiring **admiration and status**.
- This patient's **grandiosity** and entitlement differ from the **theatricality** and shallow emotional expression characteristic of histrionic behavior.
*Obsessive-compulsive personality disorder with perfectionism*
- Perfectionism in OCPD is driven by **rigidity**, a need for **control**, and preoccupation with rules rather than a desire for a "perfect" grandiose physical appearance.
- Unlike this patient, individuals with OCPD are typically **ego-syntonic regarding their work ethic** but lack the **arrogance** and self-aggrandizement seen here.
*Borderline personality disorder with identity disturbance*
- Borderline patients primarily experience **affective instability**, **fear of abandonment**, and chronic feelings of emptiness, which are not described in this scenario.
- While both can involve rage, borderline rage is usually triggered by **rejection or loss**, whereas this patient's rage stems from a blow to her **ego and superiority**.
*Body dysmorphic disorder with poor insight*
- Although she is preoccupied with her appearance, the pervasive pattern of **grandiosity**, **lack of empathy**, and **entitlement** suggests a personality structure rather than an isolated body image disorder.
- Patients with **Body Dysmorphic Disorder (BDD)** usually present with shame or distress over specific "defects" rather than a belief that they are **"destined for greatness."**
