What is the most common type of colon polyp?

• A. Pseudopolyp
• B. Tubular adenoma
• C. Villous adenoma
• D. Hyperplastic

Answer: (D)

Hyperplastic polyps are the most common colon polyps. They arise from benign mucosal hyperplasia and are non-neoplastic, typically small and located in the distal colon and rectum. They’re often found incidentally during colonoscopy and normally have no malignant potential. This sets them apart from adenomatous polyps, which are true neoplasms and precancerous; among those, tubular adenomas are the most common histologic type, though they’re less frequent overall than hyperplastic polyps. Pseudopolyps occur with inflammatory bowel disease and are not the routine sporadic polyps seen in screening.
