Mesenteric fibromatosis or intra–abdominal desmoid tumor is a rare proliferative disease affecting the mesentery. It is a locally aggressive tumor that lacks metastatic potential, but the local recurrence is common. Mesenteric fibromatosis with the intestinal involvement can be easily confused with other primary gastrointestinal tumors, especially with that of the mesenchymal origin.
