Abstract

An 80-year-old-woman was admitted to our department due to appearance of a mass in the right lower quadrant of the abdomen, with high fever and abdominal pain. She had a history of appendectomy 60 years ago and abscess drainage 30 years ago. Computed tomography (CT) scan of the abdomen showed a large abscess close to the cecal wall. Colonoscopy showed redness, edema and diverticulum of the cecum. We diagnosed an abscess from perforation of cecal diverticulum or neoplasma and planed the operation. During surgery, a giant tumor 10 centimeters long was found adjacent to the cecal wall. We performed ileocecal resection and resected the fistula by drainage tube. The mass, which contained a large quantity of mucus and necrotic tissue had a stump at the appendix. The cytological characteristics of the tumor were well differentiated adenocarcinoma which infiltrated the fibrous wall of the mass. Finally we diagnosed the tumor as mucinouscystadenocarcinoma of the remnant appendix after appendectomy.
