Figures

Figure 1
Figure 1
Colonoscopy shows a 10 mm sessile polyp with smooth edges (arrow) in the transverse colon.
Figure 2
Figure 2
The polyp was removed using snare cautery, and two clips were placed at the polypectomy site to help prevent bleeding.
Figure 3
Figure 3
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).
