A Case of Mesentem Fibromatosis with a Giant Abdominal Tumor

Abstract

Mesenteric fibromatosis is well known as a complication of familial colonic polyposis coli or Gardner's syndrome but occurs very rarely in the abdominal cavity alone. We experienced a case of mesenteric fibromatosis with a giant abdominal tumor weighing over7kg and originating in the mesenterium. This lesion is a benign tumor characterized by growth and infiltration of fibrous tissue without metastasis. Therefore complete removal of the total tumor is relatively easy and definitive surgical treatment should be performed in spite of suspicion of malignancy in the clinical findings.
