Colorectal Lymphoid Polyposis in a Child

= Abstract = Lymphoid polyposis is a lymphoid hyperplasia of the gastrointestinal tract that usually presents as multiple small polyps in the colon during childhood. This should be differentiated from other neoplastic or familial polyposis of the intestine. We report a case of benign lymphoid polyposis of the colon in a 17-month-old boy who presented with perianal fistula and mucosal ulceration. Colon study and rectal examinations showed multiple polyps in the sigmoid colon and rectum. Segmental resection of the sigmoid colon and rectum showed over 100 smallt 3 7 mrn) sessile or pedunculated polyps that were diffusely scattered through out the removed segment. The polyps consisted of mature lymphoid tissue with numerous germinal centers, that was located mostly in the lamina propria and submucosa.
