Description

Meng Huang and Jie Wu reported a teen rectal case in 2026 that looked like cancer but was not. A 17-year-old boy had two years of rectal bleeding. A scope at his local hospital showed a cauliflower-like rectal growth, and scans showed wall thickening, raising fear of a tumor. Tests also suggested ulcerative proctitis, and standard drugs for that condition failed to help.

A repeat scope showed many bumpy polyps coated with mucus. Tissue study showed healing-type tissue with distorted glands, and a team review settled on cap polyposis, a rare benign condition. Scope-based surgery removed the lesions and ended his symptoms. Checks at 4, 9, and 16 months showed healed tissue with no return.
