Intra-abdominal desmoid tumors mainly occur in cases of familial polyposis of the colon (FPC) or in the postoperative state of digestive surgery, and cases without such a history are very rare. Only 13 cases have been reported in Japan, including our case. Our case was in a 59-year-old male. The patient came to our hospital complaining of a right lower abdominal tumor, and an elastic hard tumor with good mobility was palpable. The intestinal barium examination revealed compression of the jejunum, but no evidence of polyposis in the colon. CT and MRI revealed a solid, homogeneous tumor. We therefore performed laparotomy with a preoperative diagnosis of intra-abdominal tumor. A 17×12times;9 cm tumor was found in the mesentery of the jejunum. It had a smooth surface, and was globular, grey-whitish, and solid. We resected it with approximately 0.5∼1.0 cm of normal mesentery. Pathological examination revealed it to be a desmoid tumor. Desmoid tumors generally have a high recurrence rate because of their infiltrating growth pattern, but our patient has survived in good health with no recurrence for 2 years 3 months after surgery.
