Mesenteric desmoid tumor in its cystic form: Case report of a very rare variant.

Desmoid tumors, also known as deep fibromatosis or desmoid-type fibromatosis, represent a rare subset of deep fibromatoses. It is a locally aggressive tumor, with no specific symptoms, and no metastatic potential. We report a case of a 38-year-old male patient with an abdominal mass. Radiological findings showed 2 tumors, the first was a solid inguinal mass of the left lateral iliac pedicle, and the second was a giant cystic mass in the abdominal cavity. An elective explorative laparotomy was performed to remove the 2 masses. Histopathological examination confirmed the desmoid tumor diagnosis of both lesions.
