title: Melanosis coli in hyperplastic polyps and adenomas.
abstract: Melanosis coli is a well-known occurrence in colonic biopsies. The condition is, however, reportedly absent in both neoplastic and hyperplastic colonic polyps. Herein, we describe its occurrence in 10 hyperplastic colonic polyps, some of which showed melanosis in adjacent biopsied mucosa, and 2 colonic adenomata.
