A case of mucinous cystadenoma of the appendix in a 63-year-old female is presented herein. The patient was seen in the University Hospital with a complaint of left lower quadrant abdominal mass on November 21, 1984. One year prior to this admission, she noticed a mass in the left lower quadrant of the abdomen. On admission, physical examination revealed a hard, movable mass, hen's egg in size, in the left lower quadrant. Barium enema studies demonstrated smooth displacement of the cecum by the mass. Ultrasonography and computed tomograpy showed a cystic mass with internal homogeneous material. Colonofiberscopy detected no abnormality of the cecum. At surgery, the mass appeared well circumscribed with no tumor spreads. Resection of the mass of the appendix was carried out. Grossly, the mass was 7.5×4.5×4.0cm. in size and cystic on cut section. The cyst was filled with gelatinous material. The cyst wall was 2mm. in thickness with inner smooth surface. Histologically, areas of the hyperplastic columnar epithelium with cellular stratification and atypism and hyperplastic glands with mucus columnar cells were scatteredly found. The cyst wall was hyalimzed with focal calcification with no evidence of tumor invasion. She has been doing well with no evidence of recurrence of the tumor 1.5 years since surgery.
