A well-differentiated focus of normal pancreatic tissue is found in the submucosa of the jejunum during an unrelated surgery. This lesion is best classified as a:
- A Choristoma ✓
- B Hamartoma
- C Teratoma
- D Adenoma
Correct answer: A. Choristoma
Explanation
B choristoma is a mass of normally developed tissue in an abnormal location. Ectopic pancreatic tissue in the jejunum is a classic example. B hamartoma is a disorganized overgrowth of tissues normally present at that site. B teratoma contains tissues from all three germ layers. An adenoma is a benign epithelial neoplasm.
