A 26-year-old woman consulted a gynecologist because of lower abdominal pain and an abnormal uterine discharge, and was diagnosed as having an overian dermoid cyst. She was admitted to the gynecological department of our hospital. An over fist sized-tumor was palpable in touch with the uterus by the vaginal examination, and the ultrasonography and computed tomography of the abdomen revealed an abnormal and heterogenous mass, measuring 8×4 cm, of which the margins were not clear, in the lower abdominal cavity. Exploratory laparotomy revealed a diffuse and polycystic mass with chylous fluids in the ileum, 10 to 50 cm distant from the anal end of the ileum, and also in the iliac mesentery. The ileectomy and an edge resection of the ovary was performed. Histological examination of the specimen showed cavernous lymphangioma. Lymphangioma is rarely encountered in the small intestine and is difficult to diagnose before surgery because of the anatomical features of the intestine. A case of lymphangioma of the ileum and its mesentery, suspected of an ovarial dermoid cyst was reported.
