Mesenteric fibromatosis of the small intestine is rare. It is most commonly associated with familial polyposis coli, Gardner's syndrome or prior surgical intervention. To our knowledge, without the association, only 36 cases including our case have been reported in the Japanese literature. We experienced a case of a 65-year-old man reporting an abdominal mass. Abdominal CT and angiography revealed a solid tumor in the mesentery of the small intestine. We operated on the tumor as a mesenteric tumor. The tumor, which was a solid tumor measuring 9×8.5×4cm, originated from the mesentery of the jejunum. The tumor infiltrated into the sigmoid colon, small intestine and iliopsoas muscle, so we had to remove the tumor with the jejunum, sigmoid colon, small intestine and a part of the iliopsoas muscle. Histologically, it was diagnosed as mesenteric fibromatosis. We report the isolated mesenteric fibromatosis originating in the jejunal mesenterium and review the literature.
