We report a case of mucinous adenocarcinoma in the ascending colon. A 55-year-old woman was admitted to Asan Medical Center due to right lower quadrant abdominal pain. On physical examination, an approximately 5X5 cm sized tender mass was palpated in the right lower quadrant. Colonoscopy revealed a fungating mass covered with gelatinous, yellow-whitish mucoid material in the ascending colon. Abdominal computed tomography showed irregular wall thickening from ileocecal valve to mid ascending colon with pericolic fat thickening. She underwent right hemicolectomy and surgical specimen revealed well differentiated tubulopapillary adenocarcinoma with mucinous background consistent with mucinous adenocarcinoma.
