Correct Answer » A
Explanation
|
|
- Adenomatous gastric polyps are true premalignant lesions.
- They show dysplastic epithelium and can progress to gastric adenocarcinoma.
- Risk of malignancy increases with:
- Size > 2 cm
- Villous architecture
- High-grade dysplasia
Reasons to Rule Out Other Options
B. Hyperplastic polyp
- Usually benign
- Most common gastric polyp
- Very low malignant potential
- Rare dysplasia may occur in large lesions
C. Fundic gland polyp
- Usually benign
- Commonly associated with:
- Proton pump inhibitor (PPI) use
- Familial adenomatous polyposis (FAP)
- Minimal malignant risk in sporadic cases
D. Hamartomatous polyp
- Seen in syndromes such as:
- Peutz–Jeghers syndrome
- Juvenile polyposis
- Individual polyps are not strongly premalignant compared to adenomatous polyps
