Mesenteric fibromatosis in familial polyposis. A case report and a review of Japanese cases.

A 30-year-old female with mesenteric fibromatosis (MF) associated with familial colonic polyposis (FCP) was reported together with a review of Japanese cases of simple MF. Intestinal surgery can contribute to the pathogenesis of MF more intensely in cases associated with FCP than in simple MF cases. Furthermore, the biological behaviour of MF seems to be more aggressive in the former than in the latter.
