V1-A: Cellular Adaptation, Injury & Death (Q1-25)
Q1. A 68-year-old male with a 20-year smoking history has stratified squamous
epithelium replacing the normal pseudostratified ciliated columnar epithelium in his
bronchi. This reversible change is best described as:
A. Dysplasia with disordered maturation
B. Hyperplasia with increased cell number
C. Metaplasia with replacement by a different cell type [CORRECT]
D. Hypertrophy with increased cell size
Rationale: Metaplasia is the reversible substitution of one differentiated cell type for
another, typically in response to chronic irritation. Dysplasia involves disordered
maturation and is pre-neoplastic; hyperplasia increases cell number of the same type;
hypertrophy increases cell size without type conversion.
Correct Answer: C
Q2. A bodybuilder's skeletal muscle fibers increase in diameter. This represents:
A. Hyperplasia with satellite cell proliferation
B. Hypertrophy with increased protein synthesis and myofibril number [CORRECT]
C. Metaplasia with fiber type conversion
D. Dysplasia with disordered architecture
Rationale: Skeletal muscle is a permanent cell population that responds to increased
workload through hypertrophy (increased cell size), not hyperplasia. Metaplasia and
dysplasia are not adaptive responses to mechanical loading.
Correct Answer: B

Q3. A postmenopausal woman's endometrium shows increased gland-to-stroma
ratio with back-to-back glands but no cytologic atypia. This finding represents:
A. Endometrial hyperplasia without atypia [CORRECT]
B. Endometrial carcinoma with invasion
C. Endometrial atrophy from estrogen deficiency
D. Endometrial metaplasia with squamous change
Rationale: Increased glandular proliferation without cytologic atypia defines
hyperplasia without atypia, driven by unopposed estrogen. Carcinoma requires
cytologic atypia and invasion; atrophy shows thinning; metaplasia involves cell type
change.
Correct Answer: A
Q4. A 45-year-old woman with cervical dysplasia has disordered epithelial maturation
extending through the full thickness of the epithelium. This is classified as:
A. Metaplasia with reversible adaptation
B. Cervical intraepithelial neoplasia (CIN) 3 / carcinoma in situ [CORRECT]
C. Hyperplasia with increased cell number
D. Atrophy with decreased cell layers
Rationale: Full-thickness disordered maturation without basement membrane
invasion defines CIN 3/carcinoma in situ. Metaplasia is orderly and reversible;
hyperplasia maintains normal maturation; atrophy involves thinning.
Correct Answer: B
Q5. A patient with prolonged immobilization develops muscle wasting and
decreased cell size. This process is:
A. Hypertrophy from disuse
B. Atrophy from decreased protein synthesis and autophagy [CORRECT]
,3
C. Apoptosis with programmed cell death
D. Metaplasia with fiber type switching
Rationale: Atrophy is the reduction in cell size due to decreased protein synthesis
and increased autophagy from decreased workload. Hypertrophy is the opposite;
apoptosis involves cell death; metaplasia changes cell type.
Correct Answer: B
Q6. A patient with acute myocardial infarction shows cardiac myocytes with
preserved cell outlines but loss of nuclei and cytoplasmic eosinophilia. This pattern is:
A. Liquefactive necrosis with enzymatic digestion
B. Coagulative necrosis with denatured proteins preserving architecture [CORRECT]
C. Caseous necrosis with granular debris
D. Fat necrosis with calcium saponification
Rationale: Coagulative necrosis in ischemic solid organs preserves tissue architecture
due to protein denaturation while losing nuclei. Liquefactive necrosis occurs in
brain/abscesses; caseous necrosis in TB; fat necrosis in pancreatitis/trauma.
Correct Answer: B
Q7. A patient with bacterial meningitis has brain tissue showing liquefied, pus-filled
cavities. This pattern is:
A. Coagulative necrosis from ischemia
B. Liquefactive necrosis from enzymatic digestion by neutrophils [CORRECT]
C. Caseous necrosis from TB
D. Fat necrosis from trauma
Rationale: Liquefactive necrosis occurs in the brain and abscesses due to hydrolytic
enzyme release from neutrophils, digesting tissue into liquid. Coagulative necrosis
preserves architecture; caseous and fat necrosis have distinct etiologies.
Correct Answer: B
, 4
Q8. A lung granuloma from TB shows amorphous, eosinophilic, granular debris
surrounded by epithelioid macrophages. This pattern is:
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis with cheese-like appearance [CORRECT]
D. Fat necrosis
Rationale: Caseous necrosis is characteristic of tuberculosis, showing acellular
eosinophilic granular debris without preserved architecture. The other necrosis types
have distinct morphological and etiological features.
Correct Answer: C
Q9. A patient with acute pancreatitis has chalky white deposits in the peripancreatic
fat. This represents:
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis with calcium saponification [CORRECT]
Rationale: Fat necrosis occurs when lipases digest adipocytes, releasing fatty acids
that combine with calcium to form soaps (saponification), appearing chalky white.
The other necrosis types do not involve fat digestion.
Correct Answer: D
Q10. A patient with peripheral vascular disease develops dry, shrunken, black distal
toes. This is:
A. Wet gangrene from bacterial infection
B. Dry gangrene from coagulative necrosis and desiccation [CORRECT]
