case_images: Colonoscopy was significant for sigmoid diverticulosis and a smooth, sessile 10 mm polyp in the transverse colon, which was removed with hot snare (Figures 1 and 2).
case_images: The polyp was removed using snare cautery, and two clips were placed at the polypectomy site to help prevent bleeding.

case_images: Colonoscopy was significant for sigmoid diverticulosis and a smooth, sessile 10 mm polyp in the transverse colon, which was removed with hot snare (Figures 1 and 2).
case_images: The H&E sections show proliferation of atypical lymphoid cells involving the colonic mucosa and submucosa, forming multifocal large lymphoid aggregates. H&E section on 40x shows lymphoid cells that are small in size and have scant to moderate cytoplasm. Admixed with them are scattered plasma cells (arrow).
