[Section 1: Cellular Adaptation, Injury & Neoplasia (Q1-18)]
Q1. A 30-year-old woman at 32 weeks gestation has an enlarged uterus. Histologically,
the uterine smooth muscle cells are increased in size. Which cellular adaptation is
present?
A. Hyperplasia
B. Hypertrophy [CORRECT]
C. Metaplasia
D. Dysplasia
Rationale: Hypertrophy is an increase in cell size resulting in enlarged tissue mass, as
seen in uterine smooth muscle during pregnancy; hyperplasia involves an increase in
cell number.
Correct Answer: B
Q2. A 25-year-old bodybuilder has enlarged skeletal muscle mass after 6 months of
resistance training. Which cellular adaptation explains this finding?
A. Atrophy
B. Metaplasia
C. Hypertrophy [CORRECT]
D. Dysplasia
Rationale: Skeletal muscle enlargement from increased workload is hypertrophy
(increase in cell size); hyperplasia does not occur in mature skeletal muscle cells which
are permanent cells.
Correct Answer: C
,Q3. A 45-year-old man with a 30 pack-year smoking history has bronchial epithelium
that has changed from pseudostratified ciliated columnar to stratified squamous
epithelium. Which cellular adaptation is present?
A. Hypertrophy
B. Hyperplasia
C. Metaplasia [CORRECT]
D. Anaplasia
Rationale: Metaplasia is the reversible replacement of one differentiated cell type with
another, as seen in respiratory epithelium exposed to chronic irritation from smoking; it
is a protective adaptation but can progress to dysplasia.
Correct Answer: C
Q4. A 35-year-old woman has a cervical Pap smear showing disordered epithelial
maturation with nuclear hyperchromasia and pleomorphism limited to the lower third of
the epithelium. Which cellular adaptation is present?
A. Metaplasia
B. Hyperplasia
C. Dysplasia [CORRECT]
D. Hypertrophy
Rationale: Dysplasia is characterized by disordered epithelial maturation with nuclear
pleomorphism and hyperchromasia; it is considered a pre-neoplastic lesion that may
progress to carcinoma in situ.
Correct Answer: C
Q5. A 68-year-old man with atherosclerosis suffers an acute myocardial infarction. The
affected cardiac tissue demonstrates preserved tissue architecture with loss of nuclei
and increased eosinophilia. Which type of necrosis is present?
A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis [CORRECT]
D. Fat necrosis
,Rationale: Coagulative necrosis is characteristic of ischemic injury in most solid organs
except the brain, preserving tissue architecture while denaturing proteins; it is the
classic finding in myocardial infarction.
Correct Answer: C
Q6. A 4-year-old child with meningitis shows necrotic brain tissue that has been
transformed into a viscous liquid mass. Which type of necrosis is present?
A. Coagulative necrosis
B. Liquefactive necrosis [CORRECT]
C. Caseous necrosis
D. Gangrenous necrosis
Rationale: Liquefactive necrosis occurs in the brain due to ischemic injury and bacterial
infections because neural tissue lacks supporting stroma and high lipid content triggers
enzymatic digestion; it results in soft, liquefied necrotic tissue.
Correct Answer: B
Q7. A patient with tuberculosis has granulomas containing necrotic centers that appear
soft, white, and "cheese-like" on gross examination. Which type of necrosis is present?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis [CORRECT]
D. Fat necrosis
Rationale: Caseous necrosis is characteristic of tuberculosis and granulomatous
inflammation, showing amorphous, eosinophilic debris without preserved tissue
architecture; it appears cheese-like grossly.
Correct Answer: C
Q8. A 45-year-old woman with breast trauma develops a painful, firm mass with chalky
white deposits on imaging. Histology shows necrotic adipocytes with calcium deposits.
Which type of necrosis is present?
, A. Coagulative necrosis
B. Caseous necrosis
C. Fat necrosis [CORRECT]
D. Liquefactive necrosis
Rationale: Fat necrosis occurs in adipose tissue trauma or pancreatitis (enzymatic fat
necrosis), producing chalky white calcium deposits and necrotic adipocytes with
shadowy cell outlines.
Correct Answer: C
Q9. A 70-year-old diabetic patient develops dry, shrunken, blackened gangrene of the
distal toes without evidence of infection. Which type of gangrene is present?
A. Wet gangrene
B. Gas gangrene
C. Dry gangrene [CORRECT]
D. Liquefactive gangrene
Rationale: Dry gangrene results from coagulative necrosis due to ischemia without
bacterial infection, producing shrunken, desiccated, black tissue; it typically affects the
distal extremities in patients with atherosclerosis or diabetes.
Correct Answer: C
Q10. A patient with a strangulated bowel develops necrotic intestine that is moist,
swollen, and foul-smelling with bacterial infection. Which type of gangrene is present?
A. Dry gangrene
B. Wet gangrene [CORRECT]
C. Gas gangrene
D. Coagulative necrosis only
Rationale: Wet gangrene develops when necrotic tissue is infected by bacteria,
producing moist, swollen, and foul-smelling tissue; it is common in intestines due to rich
bacterial flora and obstruction.
