title: Mucinous adenocarcinoma of colon.
abstract: Bleeding per rectum is a common complaint in pediatric age group and mostly relates to benign conditions. Underlying colorectal carcinoma is a rare cause and carries a poor prognosis. We report two cases of mucinous adenocarcinoma of colon, one in a 9 years old male and other in a female of 12 years. The boy presented with rectal bleeding and increasing constipation of more than three years duration. He had mucinous adenocarcinoma (T3N0MX) of rectosigmoid region and underwent local complete resection of the tumor with colostomy. He also received postoperative chemotherapy and later underwent colostomy reversal. He is tumor free at two years follow up. The girl presented with signs of intestinal obstruction and at colonoscopy a stricture found in descending colon. The tumor was resected and biopsy reported as poorly differentiated mucinous adenocarcinoma with positive mesenteric nodes positive for tumor (T3N2MX). She is on chemotherapy.
