Liver Tumors Indian Medical PG Practice Questions and MCQs
Question 1: What is the next best step for a 22-year-old with a hepatic hemangioma on ultrasound?
- A. Angiography
- B. CT
- C. Biopsy
- D. MRI (Correct Answer)
Explanation: ***MRI*** - **Magnetic Resonance Imaging (MRI)** is the most sensitive and specific imaging modality for confirming the diagnosis of a **hepatic hemangioma** due to its characteristic enhancement patterns. - An MRI with contrast (e.g., gadolinium) can definitively distinguish a hemangioma from other **benign or malignant liver lesions**, especially when the ultrasound findings are equivocal. *Angiography* - **Angiography** is an invasive procedure and is typically reserved for cases where **embolization** or surgical resection of a very large or symptomatic hemangioma is being considered. - It is not the initial diagnostic choice for confirming a suspected hemangioma identified on **ultrasound**. *CT* - A **CT scan** with contrast can also characterize a hemangioma, showing peripheral nodular enhancement followed by progressive centripetal fill-in. - However, **MRI** generally offers superior soft tissue contrast and provides more definitive diagnostic features for hemangiomas, particularly in younger patients where radiation exposure from CT is a concern. *Biopsy* - **Biopsy** of a suspected hepatic hemangioma is generally contraindicated due to the risk of **hemorrhage** and is rarely necessary for diagnosis. - Imaging characteristics (especially on MRI) are usually sufficient to confirm the diagnosis without the need for an invasive procedure.
Question 2: Skeletal metastasis is common in:
- A. Hepatoma
- B. Cancer stomach
- C. Cancer pancreas
- D. Cancer breast (Correct Answer)
Explanation: ***Cancer breast*** - **Breast cancer** is one of the most common primary malignancies that metastasize to bones (part of the classic **"osteophilic pentad"**: breast, prostate, lung, kidney, and thyroid) [1]. - Preferentially metastasizes to **axial skeleton** including the **spine**, **pelvis**, and **ribs**. - Bone metastases from breast cancer can be **osteolytic**, **osteoblastic**, or mixed, often causing pain and **pathological fractures**. - Approximately **70% of patients with advanced breast cancer** develop bone metastases. *Hepatoma* - **Hepatocellular carcinoma (HCC)**, or hepatoma, commonly metastasizes to the **lungs** and regional lymph nodes via hematogenous spread [2]. - While bone metastases can occur, they are **uncommon** (occurs in <5% of cases), much less frequent than with breast, prostate, or lung cancers [1]. - Bone involvement often indicates advanced disease. *Cancer stomach* - **Gastric cancer** primarily metastasizes to nearby **lymph nodes**, the **liver**, and the **peritoneum** (Krukenberg tumor to ovaries, Sister Mary Joseph nodule). - Bone metastases from gastric cancer are **relatively rare**, occurring in less than 10-15% of cases, and represent a poor prognostic sign. - Not among the common cancers with bone tropism [1]. *Cancer pancreas* - **Pancreatic cancer** frequently metastasizes to the **liver** (most common), **peritoneum**, and **lungs**. - Bone metastases are **uncommon** in pancreatic cancer (<5% of cases), typically indicating widespread disease and a very poor prognosis. - Not part of the osteophilic group of cancers [1]. **References:** [1] Cross SS.

Question 3: Most common benign tumor of the liver is:
- A. Focal nodular hyperplasia (FNH)
- B. Hepatic adenoma
- C. Hepatic hemangioma (Correct Answer)
- D. Angiomyolipoma of the liver
Explanation: ***Hepatic hemangioma*** - **Hepatic hemangiomas** are the **most common benign solid tumors of the liver**, often discovered incidentally [1]. - They are composed of a tangled mass of **blood vessels** and are generally asymptomatic [1]. *Focal nodular hyperplasia (FNH)* - FNH is the **second most common benign liver tumor**, characterized by a central scar on imaging [1]. - While benign, it is less common than hepatic hemangioma [1]. *Hepatic adenoma* - Hepatic adenomas are benign tumors with a higher risk of **hemorrhage** and **malignant transformation** compared to hemangiomas [1], [2]. - Their incidence is linked to oral contraceptive use or anabolic steroid use. *Angiolipoma of the liver* - **Angiomyolipomas** are rare benign tumors, more commonly found in the kidney, and are not the most frequent benign liver tumor. - They are composed of varying amounts of **fat**, **smooth muscle**, and **blood vessels**. **References:** [1] Cross SS. Underwood's Pathology: A Clinical Approach. 6th ed. Common Clinical Problems From Liver And Biliary System Disease, pp. 398-399. [2] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, pp. 874-875.
Question 4: A patient with a history of alcohol dependence syndrome presents with sudden and unintentional weight loss. What is the most likely diagnosis?
- A. Hepatic adenoma
- B. Cholangiocarcinoma
- C. Hepatocellular carcinoma (Correct Answer)
- D. Alcoholic hepatitis
Explanation: ***Hepatocellular carcinoma*** - The **alpha-fetoprotein (AFP)** level of **600 ng/mL** is significantly elevated, suggesting a diagnosis of hepatocellular carcinoma, especially in a patient with a history of **alcohol dependence syndrome** [1]. - The **AST/ALT ratio of 0.5** indicates significant liver damage, commonly seen in chronic liver disease leading to **hepatocellular cancer**. *Alcoholic hepatitis* - Typically presents with **elevated AST and ALT**, usually with a ratio >2:1, which is not the case here [2]. - May cause weight loss, as alcoholic patients often lose weight due to self-neglect and poor dietary intake, but the **elevated AFP** is not characteristic of merely alcoholic hepatitis [3]. *Cholangiocarcinoma* - This type of cancer primarily presents with **biliary obstruction** symptoms, such as jaundice, which is not indicated here given **normal bilirubin levels**. - Does not typically lead to such high levels of **AFP**, making it less likely with the provided lab results. *Hepatic adenoma* - More commonly associated with **oral contraceptive use** or anabolic steroid use, not primarily alcohol dependence. - AFP levels are usually normal or only mildly elevated in hepatic adenoma, making this option less viable with an **AFP level of 600 ng/mL**.
Question 5: What is a Klatskin tumor?
- A. Fibrolamellar hepatocellular carcinoma
- B. Gall bladder carcinoma
- C. Hepatocellular carcinoma
- D. Hilar cholangiocarcinoma (Correct Answer)
Explanation: ***Nodular type of cholangiocarcinoma*** - Klatskin tumors are a specific form of **cholangiocarcinoma** occurring at the junction of the left and right hepatic bile ducts [1]. - These tumors are characterized by **biliary obstruction** and often present with **jaundice** as a prominent clinical feature. *Fibrolamellar hepatocellular carcinoma* - This is a variant of **hepatocellular carcinoma** known for its fibrous stroma, distinct from Klatskin tumors which arise from bile ducts. - **Fibrolamellar** is more common in younger patients and typically does not cause **biliary obstruction** characteristic of Klatskin tumors. *Gall bladder carcinoma* - Gall bladder carcinoma originates from the **gallbladder epithelium**, not the bile ducts, differentiating it from Klatskin tumors. - It may present with symptoms such as **abdominal pain** and **weight loss**, rather than the specific obstructive jaundice seen in Klatskin cases. *Hepatocellular carcinoma* - This cancer arises directly from hepatocytes and is unrelated to bile duct tumors like Klatskin tumors. - Commonly linked to **chronic liver disease** and liver cirrhosis, it does not typically present with **obstructive jaundice** as seen in cholangiocarcinomas [1]. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, pp. 880-881.
Question 6: A patient presents with multiple secondary types of lesions in the liver, non-responding diarrhea, and flushing. It is most probably due to a lesion in:
- A. Liver
- B. Stomach
- C. Small intestine (Correct Answer)
- D. Large intestine
Explanation: ***Small intestine*** - The presence of **non-responding diarrhea** and **flushing** suggests a neuroendocrine tumor, particularly one that secretes **somatostatin**, commonly associated with the small intestine [1]. - The **multiple liver lesions** often indicate metastasis from an intestinal primary, further supporting a lesion in the small intestine [1]. *Liver* - While liver lesions are present, they are **secondary** and not the primary source of symptoms, which are more indicative of a gastrointestinal origin [1]. - Liver lesions alone do not typically cause **flushing** or **non-responding diarrhea** without an associated primary tumor in the intestine. *Stomach* - Gastric lesions can cause various symptoms but are less commonly associated with **flushing** and **diarrhea**, particularly of the non-responsive type seen here. - Stomach-specific conditions often relate more to **ulcerations** or bleeding than the systemic endocrine symptoms presented. *Large intestine* - While lesions in the large intestine can lead to **diarrhea**, they do not often present with **flushing** or involve multiple liver lesions. - This type of presentation is more characteristic of small intestinal involvement, especially in cases of **carcinoid syndrome** from neuroendocrine tumors [1].
Question 7: Which of the following statements about hepatocellular carcinoma (HCC) is true?
- A. It is resectable in early stages, depending on size, location, and liver function.
- B. More than 70% of cases show increased AFP levels.
- C. It is the most common primary liver tumor, though metastatic tumors are more common overall.
- D. All of the options. (Correct Answer)
Explanation: ***All of the options.*** - This option is correct because HCC is indeed resectable in early stages under specific conditions, AFP levels are elevated in a significant portion of cases, and it is the most common primary liver tumor. [1] - Each individual statement provides an accurate insight into the characteristics and clinical aspects of hepatocellular carcinoma. [2] *It is resectable in early stages, depending on size, location, and liver function.* - **Early-stage HCC** can be potentially cured with **surgical resection** or liver transplantation, provided the tumor is small, solitary, and the patient has good liver function. [2] - The decision for resectability is complex and depends on factors such as **tumor size, location**, and the patient's **Child-Pugh score** or MELD score for liver function. *More than 70% of cases show increased AFP levels.* - **Alpha-fetoprotein (AFP)** is a widely used **tumor marker** for HCC, and elevated levels are observed in 60-80% of patients, particularly those with larger tumors. [1] - While helpful for screening and monitoring, AFP is not specific enough for diagnosis on its own, as it can also be elevated in other liver conditions and germ cell tumors. *It is the most common primary liver tumor, though metastatic tumors are more common overall.* - **Hepatocellular carcinoma (HCC)** accounts for about 80-90% of **primary liver cancers**, making it the most prevalent type originating in the liver. - However, **metastatic liver cancer**, meaning cancer that has spread to the liver from another primary site (e.g., colon, lung, breast), is significantly more common in the general population than primary liver cancers.
Question 8: Statement 1 - A 59-year-old patient presents with flaccid bullae. Histopathology shows a suprabasal acantholytic split. Statement 2 - The row of tombstones appearance is diagnostic of Pemphigus vulgaris.
- A. Statements 1 & 2 are correct, 2 is not explaining 1 (Correct Answer)
- B. Statements 1 and 2 are correct and 2 is the correct explanation for 1
- C. Statements 1 and 2 are incorrect
- D. Statement 1 is incorrect
Explanation: ***Correct: Statements 1 & 2 are correct, 2 is not explaining 1*** **Analysis of Statement 1:** - A 59-year-old patient with **flaccid bullae** and **suprabasal acantholytic split** on histopathology is the classic presentation of **Pemphigus vulgaris** - The flaccid (easily ruptured) nature of bullae distinguishes it from tense bullae seen in bullous pemphigoid - The suprabasal location of the split (just above the basal layer) with acantholysis (loss of cell-to-cell adhesion) is pathognomonic - **Statement 1 is CORRECT** ✓ **Analysis of Statement 2:** - The **"row of tombstones" or "tombstone appearance"** is indeed a diagnostic histopathological feature of Pemphigus vulgaris - This appearance results from basal keratinocytes remaining attached to the basement membrane while suprabasal cells separate due to acantholysis - The intact basal cells standing upright resemble a row of tombstones - **Statement 2 is CORRECT** ✓ **Does Statement 2 explain Statement 1?** - Statement 2 describes a **histopathological appearance** (tombstone pattern) that is a **consequence** of the suprabasal split - However, it does NOT explain the **underlying cause** of the flaccid bullae or the suprabasal split - The true explanation involves **IgG autoantibodies against desmoglein 3 (and desmoglein 1)**, which attack intercellular adhesion structures (desmosomes), causing **acantholysis** - Therefore, **Statement 2 does NOT explain Statement 1** ✗ *Incorrect: Statement 2 is the correct explanation for Statement 1* - While both statements describe features of Pemphigus vulgaris, the tombstone appearance is a descriptive finding, not an explanatory mechanism *Incorrect: Statements 1 and 2 are incorrect* - Both statements are medically accurate descriptions of Pemphigus vulgaris features *Incorrect: Statement 1 is incorrect* - Statement 1 correctly describes the cardinal clinical and histopathological features of Pemphigus vulgaris
Question 9: Which of the following liver tumors has a propensity to invade the portal or hepatic vein?
- A. Cavernous hemangioma
- B. Hepatocellular carcinoma (Correct Answer)
- C. Focal nodular hyperplasia
- D. Hepatic adenoma
Explanation: ***Hepatocellular carcinoma*** - **Hepatocellular carcinoma (HCC)** is known for its aggressive nature and a characteristic tendency to invade vascular structures, particularly the **portal vein** or hepatic veins [1]. - This **vascular invasion** contributes to its metastatic potential and is a critical factor in prognosis and treatment planning [1].*Cavernous hemangioma* - A **cavernous hemangioma** is a benign vascular tumor of the liver, typically recognized as an incidental finding. - While it is a vascular lesion, it does not invade the large hepatic or portal veins but rather consists of **dilated vascular spaces** within the liver parenchyma.*Focal nodular hyperplasia* - **Focal nodular hyperplasia (FNH)** is a **benign liver lesion** characterized by a central fibrous scar and radiating septa [2]. - It is typically well-circumscribed and does not exhibit aggressive features like **vascular invasion** [2].*Hepatic adenoma* - A **hepatic adenoma** is a benign tumor, often associated with oral contraceptive use, which can sometimes pose a risk of rupture or malignant transformation. - However, it does not typically show features of **vascular invasion** into the portal or hepatic veins [2]. **References:** [1] Kumar V, Abbas AK, et al.. Robbins and Cotran Pathologic Basis of Disease. 9th ed. Liver and Gallbladder, pp. 878-879. [2] Cross SS. Underwood's Pathology: A Clinical Approach. 6th ed. Common Clinical Problems From Liver And Biliary System Disease, pp. 398-399.
Question 10: Which is a hormone dependent liver tumor?
- A. Adenoma (Correct Answer)
- B. Hemangioma
- C. Hepatocellular carcinoma
- D. Hemangiopericytoma
Explanation: ***Adenoma*** - Hepatic adenomas are **hormone-dependent tumors** commonly associated with conditions like **oral contraceptive use** and are influenced by estrogen [1]. - These tumors can present as **benign liver masses**, but they have a risk of hemorrhage and malignant transformation [1]. *Hepatocellular carcinoma* - This is a **malignant tumor** of the liver primarily associated with cirrhosis and chronic liver disease, not directly hormone-dependent. - Risk factors include **viral hepatitis** and **alcohol exposure**, rather than hormonal influences. *Hemangioma* - Liver hemangiomas are **vascular lesions** that are usually asymptomatic and are **not hormone-dependent**. - They are the most common benign liver tumors, often discovered incidentally during imaging. *Hemangiopericytoma* - A rare tumor, hemangiopericytoma originates from **pericytes** around blood vessels and is not specifically associated with liver tissue or hormones. - It can arise in various organs but lacks the dependency on hormones seen in hepatic adenomas. **References:** [1] Kumar V, Abbas AK, et al..
