Pathology MCQs
Pathology MCQs are designed to test a student's understanding of disease mechanisms, histopathology, and clinical correlations. Questions range from general pathology to systemic diseases affecting organs like the liver, lungs, heart, and kidneys. Ideal for MDCAT, NTS, USMLE, and FCPS aspirants, these quizzes help reinforce critical concepts and bridge the gap between theory and clinical application.

A) Well-circumscribed margins
B) Poor differentiation
C) Invasion of adjacent tissue

Q: Coagulative necrosis is typically observed in
A) Pancreatitis
B) Lung infarction
C) Brain infarction
D) Myocardial infarction
✅ Correct Answer: D
Explanation: Myocardial infarction classically results in coagulative necrosis due to ischemia.
Q: The most common cause of iron deficiency anemia worldwide
A) Blood loss
B) Chronic kidney disease
C) Nutritional deficiency
D) Malaria
✅ Correct Answer: A

B) Hyperplastic
C) Hypertrophic
D) Anaplastic
✅ Correct Answer: D
Explanation: Anaplastic tumors show poor differentiation, pleomorphism, and aggressive behavior.
Q: A primary characteristic of dysplasia
A) Loss of cellular polarity
