A51-year-old woman reported discomfort in the right lower abdomen from around July 1999. Black feceswere seen from February 2000. A fist-sized tumor was felt at the right lower abdomen. Endoscopy of thelarge intestine showed blood accumulating in the ascending colon but no tumor. Suspected of hemorrhagein the small intestine, the patient was hospitalized. CT and MRI indicated a tumor in the pelvis. Surgeryshowed a tumor in the right pelvic cavity closely associated with the appendix, presenting infiltrativeadhesion with the uterus and the right ovary, and direct infiltration to the terminal end of the ileum. Basedon the diagnosis of appendix cancer, we excised an ileocecal segment, extracted the entire uterus andremoved bilateral adnexes. Histopathological examination showed cystadenocarcinoma in the mucosa ofthe appendix, the cause of melena probably resulted from the infiltration of appendix cancer into the ileum.
