Question 691: A 24-year-old male complained of recurrent attacks of sore throat for the past 2 years. His total leukocyte count was 3000/μl. A differential count revealed severe neutropenia. What is the most likely diagnosis?

A. Subleukemic leukemia
B. Agranulocytosis (Correct Answer)
C. Infectious mononucleosis
D. Leukoerythroblastic anemia

Explanation: ### Explanation **Correct Answer: B. Agranulocytosis** **1. Why Agranulocytosis is correct:** Agranulocytosis is characterized by a severe reduction in the number of circulating granulocytes (specifically neutrophils < 500/μl). The clinical hallmark of this condition is a **predisposition to severe, recurrent infections**, most commonly presenting as **ulcerating necrotizing lesions of the gingiva, floor of the mouth, or pharynx (agranulocytic angina)**. In this case, the patient’s recurrent sore throats and total leukocyte count of 3000/μl with severe neutropenia perfectly align with this diagnosis [1]. It is often drug-induced (e.g., Clozapine, PTU) or due to bone marrow suppression [1]. **2. Why the other options are incorrect:** * **A. Subleukemic leukemia:** While the total WBC count may be low or normal in subleukemic leukemia, the peripheral blood must show the presence of **abnormal/blast cells** [2]. The clinical history of recurrent sore throat over 2 years is more suggestive of chronic/recurrent neutropenia than acute leukemia. * **C. Infectious mononucleosis:** This typically presents with **lymphocytosis** (increased WBC count) and the presence of atypical lymphocytes (Downey cells), not severe neutropenia. * **D. Leukoerythroblastic anemia:** This refers to the presence of immature white cells and nucleated red cells in the peripheral blood, usually due to **marrow-occupying lesions** (myelophthisis). It is not defined by isolated neutropenia. **3. High-Yield Clinical Pearls for NEET-PG:** * **Definition:** Neutropenia is ANC < 1500/μl; Agranulocytosis is ANC < 500/μl. * **Morphology:** In the bone marrow, agranulocytosis may show "maturation arrest" at the promyelocyte stage. * **Common Culprits:** Always remember **Clozapine, Carbamazepine, Propylthiouracil (PTU), and Methimazole** as high-yield drug causes of agranulocytosis [1]. * **Treatment:** The primary treatment involves removing the offending agent and administering **G-CSF** (Granulocyte Colony-Stimulating Factor). **References:** [1] Kumar V, Abbas AK, et al..

Question 692: The expression of JAK2 mutation is seen in all conditions, EXCEPT:

A. Chronic eosinophilic leukemia (Correct Answer)
B. Primary myelofibrosis
C. Polycythemia vera
D. Essential thrombocytosis

Explanation: The question tests your knowledge of **Myeloproliferative Neoplasms (MPNs)** and their associated molecular markers. ### **Explanation** The **JAK2 (Janus Kinase 2)** mutation is a hallmark of "classic" BCR-ABL negative MPNs [1]. It leads to constitutive activation of the JAK-STAT signaling pathway, causing autonomous cellular proliferation. * **Why Chronic Eosinophilic Leukemia (CEL) is the correct answer:** CEL is typically associated with rearrangements involving **PDGFRα, PDGFRβ, or FGFR1** (most commonly the *FIP1L1-PDGFRA* fusion gene) [1]. While JAK2 mutations are central to classic MPNs, they are not a defining or common feature of CEL. Therefore, it is the "exception" in this list. ### **Analysis of Other Options** * **Polycythemia Vera (PV):** Nearly **>95%** of cases harbor the JAK2 V617F mutation (Exon 14), with the remainder often having JAK2 Exon 12 mutations [1], [2]. It is the most strongly associated condition. * **Essential Thrombocythemia (ET):** Approximately **50–60%** of patients express the JAK2 V617F mutation [1], [2]. Other mutations include CALR and MPL [1]. * **Primary Myelofibrosis (PMF):** Similar to ET, about **50–60%** of cases are JAK2 V617F positive [1]. ### **High-Yield Clinical Pearls for NEET-PG** 1. **JAK2 V617F Mutation:** A point mutation where Valine is replaced by Phenylalanine at codon 617 [2]. 2. **Triple Negative MPNs:** Refers to ET or PMF cases lacking JAK2, CALR, and MPL mutations [3]. 3. **FIP1L1-PDGFRA:** The most common molecular abnormality in CEL/Hypereosinophilic syndrome [1]; notably, these patients respond excellently to **Imatinib**. 4. **Diagnostic Hierarchy:** In any suspected MPN, testing for JAK2 is the first-line molecular investigation. **References:** [1] Kumar V, Abbas AK, et al..

Question 693: Reed-Sternberg cells are characteristically seen in which of the following conditions?

A. Alpha-thalassemia
B. Glandular fever
C. Hansen's disease
D. Hodgkin's disease (Correct Answer)

Explanation: ### Explanation **Correct Answer: D. Hodgkin's disease** **Understanding the Concept:** Reed-Sternberg (RS) cells are the diagnostic hallmark of **Hodgkin’s Lymphoma (HL)** [1]. These are large, multinucleated (or bilobed) B-cells with a characteristic **"Owl’s eye" appearance**, featuring prominent eosinophilic inclusion-like nucleoli [2]. While they are essential for diagnosis, they typically represent only 1–5% of the total tumor mass; the remainder consists of a reactive background of lymphocytes, plasma cells, and eosinophils [1]. Classically, RS cells express **CD15 and CD30** (except in the Nodular Lymphocyte Predominant subtype). **Analysis of Incorrect Options:** * **A. Alpha-thalassemia:** This is a microcytic hypochromic anemia caused by deficient synthesis of alpha-globin chains. Peripheral smears characteristically show **target cells** and Heinz bodies (in HbH disease), not RS cells. * **B. Glandular fever (Infectious Mononucleosis):** Caused by the Epstein-Barr Virus (EBV), this condition features **Downey cells** (atypical T-lymphocytes). While "RS-like" cells can occasionally be seen, they are not a characteristic diagnostic feature of this benign condition. * **C. Hansen's disease (Leprosy):** This is a chronic granulomatous infection caused by *Mycobacterium leprae*. Histology shows **Virchow cells** (foamy macrophages containing lepra bacilli), not RS cells. **NEET-PG High-Yield Pearls:** * **Variants of RS cells:** * *Lacunar cells:* Seen in Nodular Sclerosis HL [2]. * *Popcorn cells (L&H cells):* Seen in Nodular Lymphocyte Predominant HL (CD20+) [4]. * *Mummified cells:* Degenerated RS cells seen in Mixed Cellularity HL. * **Immunophenotype:** Classic HL is **CD15+, CD30+, CD45–**. * **EBV Association:** Most strongly associated with the **Mixed Cellularity** subtype [3]. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Diseases of White Blood Cells, Lymph Nodes, Spleen, and Thymus, pp. 614-616. [2] Kumar V, Abbas AK, et al..

Question 694: Chediak Higashi syndrome is characterized by which of the following?

A. Giant granules in leukocytes
B. Albinism
C. Mutation in LYST gene
D. All the above (Correct Answer)

Explanation: **Explanation:** Chediak-Higashi Syndrome (CHS) is a rare autosomal recessive disorder characterized by a defect in **intracellular protein trafficking** [1]. The underlying pathology is a mutation in the **LYST gene** (Lysosomal Trafficking Regulator), which leads to the failure of phagosome-lysosome fusion [1]. * **Giant Granules in Leukocytes:** Due to the defect in vesicle fusion, lysosomes and secretory granules fuse uncontrollably, forming pathognomonic **giant azurophilic granules** in neutrophils, eosinophils, and monocytes [1]. These are visible on a peripheral blood smear. * **Albinism:** The LYST mutation also affects melanocytes. Melanin cannot be properly distributed from melanosomes to keratinocytes, resulting in **oculocutaneous albinism** (silvery hair and light skin) [1]. * **Mutation in LYST gene:** This is the primary genetic defect located on chromosome 1q42. Since all three features are hallmark characteristics of the disease, **Option D (All the above)** is the correct answer. **High-Yield Clinical Pearls for NEET-PG:** * **Immunodeficiency:** Patients suffer from recurrent pyogenic infections (especially *Staphylococcus aureus*) due to impaired chemotaxis and delayed microbial killing [1]. * **Neuropathy:** Progressive neurological deterioration (ataxia, tremors, and peripheral neuropathy) is common in survivors [1]. * **Bleeding Diathesis:** Caused by a deficiency in platelet dense bodies [1]. * **Accelerated Phase:** A life-threatening "hemophagocytic lymphohistiocytosis" (HLH)-like syndrome triggered by viral infections (often EBV), leading to hepatosplenomegaly and pancytopenia. * **Diagnosis:** Peripheral smear showing giant peroxidase-positive granules in neutrophils. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Diseases of the Immune System, pp. 245-246.

Question 695: All of the following are true regarding Chronic Lymphocytic Leukemia (CLL) except?

A. Most common type of leukemia in adults
B. Males are commonly affected
C. ZAP-70 has prognostic importance
D. Affects T-cells (Correct Answer)

Explanation: ### Explanation **Chronic Lymphocytic Leukemia (CLL)** is a monoclonal proliferation of morphologically mature but immunologically incompetent lymphocytes [1]. **1. Why Option D is the Correct Answer (The False Statement):** CLL is a **B-cell neoplasm**, not a T-cell disorder [1]. The neoplastic cells typically express B-cell markers such as **CD19, CD20, and CD23** [2]. A characteristic diagnostic feature is the aberrant co-expression of **CD5**, a marker normally found on T-cells, which can sometimes lead to confusion; however, the lineage remains B-cell [2], [3]. **2. Analysis of Other Options:** * **Option A:** CLL is indeed the **most common leukemia in adults** in Western countries and is frequently encountered in the elderly population in India [1]. * **Option B:** There is a distinct gender predilection, with **males affected twice as often** as females (M:F ratio approx. 2:1). * **Option C:** **ZAP-70** and **CD38** are critical prognostic markers. High expression of ZAP-70 (≥20%) correlates with unmutated *IGHV* genes, signifying a **poor prognosis** and more aggressive disease course. **3. Clinical Pearls for NEET-PG:** * **Peripheral Smear:** Characterized by "Smudge cells" or "Basket cells" (fragile lymphocytes that burst during slide preparation) [2]. * **Richter Transformation:** In 5-10% of cases, CLL can transform into a high-grade **Diffuse Large B-Cell Lymphoma (DLBCL)**, marked by sudden clinical worsening. * **Immunophenotype:** CD5+, CD19+, CD20+ (weak), CD23+, and Cyclin D1 negative (to differentiate from Mantle Cell Lymphoma) [2]. * **Hypogammaglobulinemia:** Common in late stages, leading to increased susceptibility to bacterial infections. **References:** [1] Cross SS.

Question 696: Microscopy of a specimen shows "pawn ball megakaryocytes". This finding is associated with which of the following conditions?

A. Myelodysplastic syndrome (Correct Answer)
B. Idiopathic thrombocytopenic purpura
C. Thrombotic thrombocytopenic purpura
D. Chloramphenicol toxicity

Explanation: **Explanation:** The presence of **"pawn ball megakaryocytes"** is a classic morphological hallmark of **Myelodysplastic Syndrome (MDS)**. These are small, mononuclear megakaryocytes (micromegakaryocytes) or megakaryocytes with multiple, small, widely separated nuclei, resembling the shape of a chess pawn. 1. **Why MDS is correct:** MDS is characterized by **ineffective hematopoiesis** leading to peripheral cytopenias and hypercellular bone marrow with dysplastic changes [1]. Dysmegakaryopoiesis is a key feature, manifesting as pawn ball megakaryocytes or micromegakaryocytes. This reflects a maturation defect in the myeloid lineage [1]. 2. **Why the others are incorrect:** * **ITP (Idiopathic Thrombocytopenic Purpura):** The bone marrow typically shows an *increase* in the number of megakaryocytes (compensatory), but they are morphologically normal or slightly larger, not dysplastic. * **TTP (Thrombotic Thrombocytopenic Purpura):** This is a microangiopathic hemolytic anemia (MAHA) caused by ADAMTS13 deficiency. It involves peripheral platelet consumption; the marrow is usually normal or shows reactive erythroid hyperplasia. * **Chloramphenicol Toxicity:** This typically causes **aplastic anemia** (pancytopenia with hypocellular marrow) or reversible mitochondrial suppression. It does not specifically produce pawn ball megakaryocytes. **High-Yield Clinical Pearls for NEET-PG:** * **MDS Cytogenetics:** The most common chromosomal abnormality is **5q deletion** (associated with a better prognosis and response to Lenalidomide) [1]. * **Ring Sideroblasts:** Another classic MDS finding (seen with Prussian blue stain) due to iron accumulation in mitochondria. * **Pseudo-Pelger-Huët Anomaly:** Hyposegmented, bilobed neutrophils (spectacle-shaped) also seen in MDS [1]. * **Transformation:** MDS is considered a "pre-leukemic" state as it can transform into **Acute Myeloid Leukemia (AML)** [1]. **References:** [1] Cross SS. Underwood's Pathology: A Clinical Approach. 6th ed. Common Clinical Problems From Blood And Bone Marrow Disease, pp. 613-614.

Question 697: In which of the following conditions can Downey cells be seen?

A. Small lymphocytic lymphoma
B. Acute myeloid leukemia
C. Infectious mononucleosis (Correct Answer)
D. Multiple myeloma

Explanation: **Explanation:** **Infectious Mononucleosis (IM)** is the classic condition associated with **Downey cells** [1]. These are **atypical T-lymphocytes** (specifically CD8+ cytotoxic T-cells) that have been activated in response to B-cells infected by the **Epstein-Barr Virus (EBV)**. Morphologically, Downey cells are larger than mature lymphocytes, featuring abundant, "balloons-out" cytoplasm that often indents or "hugs" adjacent red blood cells, and a nucleus with coarse or smudged chromatin [1]. **Analysis of Incorrect Options:** * **Small Lymphocytic Lymphoma (SLL):** Characterized by small, mature-looking lymphocytes and "Smudge cells" (fragile cells that burst during smear preparation), not atypical reactive T-cells. * **Acute Myeloid Leukemia (AML):** Defined by the presence of myeloblasts (containing Auer rods) rather than reactive lymphocytes. * **Multiple Myeloma:** A plasma cell dyscrasia characterized by malignant plasma cells in the bone marrow, often showing "Fried egg" appearance or "Mott cells," but not Downey cells. **High-Yield Clinical Pearls for NEET-PG:** * **Triad of IM:** Fever, pharyngitis, and lymphadenopathy (posterior cervical) [1]. * **Diagnosis:** Heterophile antibody test (**Monospot test**) is the screening gold standard. * **The "Indentation" Sign:** The cytoplasm of Downey cells scalloping around RBCs is a classic morphological descriptor in exams [1]. * **Complication:** Avoid contact sports due to the risk of **splenic rupture**. * **Antibiotic Caution:** Administration of Ampicillin/Amoxicillin in IM patients often results in a characteristic maculopapular rash. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Infectious Diseases, pp. 369-370.

Question 698: Disseminated Intravascular Coagulation (DIC) is commonly seen in which subtype of Acute Myeloid Leukemia (AML)?

A. M1 AML
B. M2 AML
C. M3 AML (Correct Answer)
D. M4 AML

Explanation: **Explanation:** **Correct Option: C (M3 AML)** Acute Promyelocytic Leukemia (APL), classified as **FAB M3**, is the subtype most strongly associated with **Disseminated Intravascular Coagulation (DIC)** [1]. This is a medical emergency. The underlying mechanism involves the presence of numerous primary granules in the malignant promyelocytes. These granules contain **Tissue Factor-like procoagulants** and **fibrinolytic enzymes**. When these cells die (either naturally or due to chemotherapy), they release these substances into the circulation, triggering the extrinsic coagulation pathway and systemic fibrinolysis, leading to life-threatening hemorrhage and microvascular thrombosis. **Incorrect Options:** * **A (M1 AML):** AML without maturation. It lacks the significant granular content required to trigger massive DIC. * **B (M2 AML):** AML with maturation. While it is the most common subtype of AML, it is typically associated with the t(8;21) translocation and chloromas (granulocytic sarcomas), not primary DIC. * **D (M4 AML):** Acute Myelomonocytic Leukemia. This subtype (specifically M4eo) is characterized by gum hypertrophy and skin involvement due to monocytic infiltration, rather than coagulopathy. **High-Yield Clinical Pearls for NEET-PG:** * **Cytogenetics:** M3 is associated with **t(15;17)**, involving the *PML-RARα* fusion gene [1]. * **Morphology:** Look for **Auer rods** (often in bundles called **Faggot cells**) [1]. * **Treatment:** The standard of care is **All-trans Retinoic Acid (ATRA)**, which induces the maturation of promyelocytes into neutrophils, bypassing the massive release of procoagulants. * **Stain:** M3 shows strong positivity for **Myeloperoxidase (MPO)**. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Diseases of White Blood Cells, Lymph Nodes, Spleen, and Thymus, pp. 620-622.

Question 699: Which of the following conditions is NOT associated with increased risk of infective endocarditis?

A. Infective endocarditis (Correct Answer)
B. Sickle cell disease
C. Celiac disease
D. Thrombocythemia

Explanation: **Explanation:** The question asks for the condition **NOT** associated with an increased risk of **Infective Endocarditis (IE)**. This is a conceptual question focusing on the risk factors for IE versus the complications of splenic dysfunction. **1. Why "Infective Endocarditis" is the correct answer:** Infective endocarditis is a **clinical diagnosis/outcome**, not a predisposing risk factor in the same category as the others listed [2]. While a *previous history* of IE is a major risk factor for recurrence, the condition itself is the endpoint [3]. In the context of this question, it serves as the "odd one out" compared to the other options which all lead to a specific physiological state: **Hyposplenism.** **2. Analysis of Incorrect Options (Risk Factors for IE):** Options B, C, and D are all associated with **functional or anatomical asplenia/hyposplenism**: * **Sickle Cell Disease:** Causes "autosplenectomy" due to repeated splenic infarctions. * **Celiac Disease:** Frequently associated with functional hyposplenism (atrophy of splenic lymphoid tissue). * **Thrombocythemia (Essential):** Can lead to splenic infarction or congestion, impairing its filtering function. **The Pathophysiological Link:** The spleen is responsible for filtering encapsulated bacteria (e.g., *S. pneumoniae*, *H. influenzae*) and producing opsonizing antibodies. Patients with hyposplenism are at a significantly higher risk of **overwhelming post-splenectomy infection (OPSI)** and bacteremia. Since bacteremia is the primary precursor to infective endocarditis, any condition causing hyposplenism indirectly increases the risk of IE [1]. **High-Yield NEET-PG Pearls:** * **Most common cause of IE (Native Valve):** *Staphylococcus aureus* (previously *Viridans streptococci*) [1]. * **Most common cause of IE (IV Drug Users):** *Staphylococcus aureus* (Tricuspid valve involvement) [1]. * **Hyposplenism Signs on Peripheral Smear:** Howell-Jolly bodies, Pappenheimer bodies, and Target cells. * **Prophylaxis:** Patients with high-risk cardiac conditions (e.g., prosthetic valves) require antibiotic prophylaxis before certain dental procedures [4]. **References:** [1] Kumar V, Abbas AK, et al..

Question 700: Haemophilia A and Von Willebrand's disease are coagulation disorders due to deficiency of which factor?

A. Factor IX
B. Vitamin K
C. Factor X
D. Factor VIII (Correct Answer)

Explanation: **Explanation:** The correct answer is **Factor VIII**. Both Hemophilia A and Von Willebrand Disease (vWD) are linked to the Factor VIII complex, though their underlying mechanisms differ. 1. **Hemophilia A:** This is an X-linked recessive disorder caused by a quantitative deficiency or functional defect in **Factor VIII (anti-hemophilic factor)** [1]. It primarily affects the intrinsic pathway of coagulation, leading to a prolonged Activated Partial Thromboplastin Time (aPTT). Hemophilia A exhibits a wide range of clinical severity that correlates well with the level of factor VIII activity [1]. 2. **Von Willebrand Disease:** This is the most common inherited bleeding disorder. Von Willebrand Factor (vWF) serves two main roles: it mediates platelet adhesion to subendothelial collagen and acts as a **carrier protein that stabilizes Factor VIII** in the circulation. In vWD, the lack of vWF leads to a secondary decrease in Factor VIII levels because the factor is rapidly degraded without its carrier. **Analysis of Incorrect Options:** * **Factor IX (Option A):** Deficiency causes **Hemophilia B** (Christmas Disease). Clinically indistinguishable from Hemophilia A but requires different factor replacement. * **Vitamin K (Option B):** Vitamin K is essential for the gamma-carboxylation of Factors **II, VII, IX, and X**, as well as Proteins C and S. Deficiency affects both PT and aPTT. * **Factor X (Option C):** This is the start of the common pathway. Deficiency is rare and leads to prolongation of both PT and aPTT. **NEET-PG High-Yield Pearls:** * **Mixing Study:** In Hemophilia A, aPTT corrects with normal plasma (indicates deficiency). If it doesn't correct, suspect an inhibitor. * **vWD Clinical Presentation:** Characterized by mucosal bleeding (epistaxis, menorrhagia) and a prolonged **Bleeding Time (BT)** due to defective platelet adhesion, alongside a prolonged aPTT. * **Treatment:** Desmopressin (DDAVP) can be used in mild Hemophilia A and Type 1 vWD as it releases stored vWF and Factor VIII from Weibel-Palade bodies. **References:** [1] Kumar V, Abbas AK, et al..
