,Section 1: Cellular & Tissue Pathophysiology
Q1
A 62-year-old patient with a 40-pack-year smoking history presents with a persistent cough and
hemoptysis. A biopsy of the lung mass reveals cells with large hyperchromatic nuclei, scant cytoplasm,
and nuclear molding. The pathologist identifies these as small round blue cells. These histologic features
are most characteristic of:
A. Squamous cell carcinoma arising from the bronchial epithelium.
B. Small cell lung cancer with neuroendocrine differentiation.
C. Adenocarcinoma with lepidic growth pattern.
D. Large cell neuroendocrine carcinoma with prominent nucleoli.
Correct Answer: B
Rationale: Small cell lung cancer is characterized by small round blue cells with scant cytoplasm, nuclear molding, and
hyperchromatic nuclei. These cells are of neuroendocrine origin and are strongly associated with smoking. Squamous cell
carcinoma shows keratin pearls, and adenocarcinoma forms glandular structures.
Q2
A patient with chronic sun exposure develops a raised, pearly papule with telangiectasias on the nasal
bridge. Microscopic examination shows basaloid cells with peripheral palisading and retraction artifact
from the surrounding stroma. These findings are diagnostic of:
A. Squamous cell carcinoma in situ with atypical keratinocytes.
B. Basal cell carcinoma with nodular growth pattern.
C. Malignant melanoma with superficial spreading subtype.
D. Actinic keratosis with full-thickness epidermal dysplasia.
Correct Answer: B
Rationale: Basal cell carcinoma classically presents as pearly papules with telangiectasias and shows basaloid cells with
peripheral palisading and stromal retraction. It is the most common skin cancer but rarely metastasizes. Melanoma shows
atypical melanocytes, and actinic keratosis is a premalignant lesion.
, Q3
A 45-year-old woman presents with progressive fatigue, jaundice, and pruritus. Liver biopsy reveals
dense lymphocytic infiltration of the portal tracts with piecemeal necrosis of hepatocytes at the limiting
plate. Serum ANA and anti-smooth muscle antibodies are elevated. These findings are most consistent
with:
A. Primary biliary cholangitis with granulomatous bile duct destruction.
B. Autoimmune hepatitis with interface hepatitis.
C. Primary sclerosing cholangitis with onion-skin fibrosis.
D. Nonalcoholic steatohepatitis with ballooning degeneration.
Correct Answer: B
Rationale: Autoimmune hepatitis is characterized by interface hepatitis (piecemeal necrosis), portal lymphoplasmacytic
infiltrate, and positive autoantibodies (ANA, anti-smooth muscle). Primary biliary cholangitis affects bile ducts and is
anti-mitochondrial antibody positive. PSC shows concentric periductal fibrosis.
Q4
A patient with familial adenomatous polyposis develops hundreds of adenomatous polyps throughout
the colon. Genetic testing reveals a mutation in the APC tumor suppressor gene on chromosome 5q21.
The pathophysiologic mechanism by which this mutation leads to colorectal cancer involves:
A. Activation of the Wnt signaling pathway leading to uncontrolled cellular proliferation.
B. Inhibition of DNA mismatch repair causing microsatellite instability.
C. Overexpression of the HER2 receptor promoting epithelial cell growth.
D. Loss of the p53 cell cycle checkpoint resulting in aneuploidy.
Correct Answer: A
Rationale: The APC gene normally degrades beta-catenin, a key mediator of Wnt signaling. Mutant APC allows beta-catenin
accumulation, activating transcription of proliferation genes like c-MYC and cyclin D1. This is the initiating event in the
adenoma-carcinoma sequence. DNA mismatch repair defects cause Lynch syndrome.
Q5
A patient with Barrett esophagus undergoes endoscopic surveillance. Biopsy reveals columnar
epithelium with goblet cells and areas of high-grade dysplasia. The pathophysiologic progression from
Barrett esophagus to adenocarcinoma is driven primarily by:
A. Chronic reflux of gastric acid and bile salts causing DNA damage in esophageal stem cells.
B. Helicobacter pylori infection triggering chronic mucosal inflammation.
C. Autoimmune destruction of the lower esophageal sphincter smooth muscle.
D. Viral oncogene insertion by human papillomavirus subtype 16.
Correct Answer: A
Rationale: Chronic gastroesophageal reflux exposes the distal esophagus to gastric acid, pepsin, and bile salts, causing DNA
damage and metaplastic change from squamous to intestinal-type columnar epithelium. This metaplasia-dysplasia-carcinoma
sequence is the hallmark of Barrett-related adenocarcinoma.
