A 37-year-old man was admitted to the hospital because of lower abdominal pain. On admission, a fist-sized tumor with smooth surface associated with tenderness was palpated in the lower abdomen. On blood analysis, mild inflammatory findings were noted. Abdominal CT scan and magnetic resonance imaging revealed a soft parts tumor with calcification in the pelvic cavity. Angiography of teh superior mesenteric artery visualized accumulation of a contrast material. From these findings, a laparotomy was performed with a suspicion of a tumor arising in the mesentery or small intestine. At surgery, a tumor about 10 cm in size was present on the middle portion of the mesentery. A partial excision of the small intestine including the tumor was performed. The tumor was white in color and an elastic hard spherical tumor. Histopathologically, it was mainly composed of fibroblasts and collagen fibrils, and was diagnosed as desmoid tumor arisen in the mesentery. Postoperative course was uneventful. The patient was discharged from the hospital on the 16th postoperative day. Since the desmoid tumor is a rare entity, this case is presented with a review of the literature.
