Fibromatosis mesentérica. Reporte de un caso* Mesenteric fibromatosis. Report of one case

Desmoid tumor or mesenteric fibromatosis is an uncommon disease with to variants: a sporadic form and one associated to familial adenomatous polyposis. Surgery is the treatment of choice. We report a 45 years old male presenting with abdominal pain and fever. An abdominal ultrasound informed the presence of a mass in the periumblical area. An Abdominal CAT scan showed a 13 cm diameter solid mass located in the left upper quadrant. The patient was operated and that mass is excised, requiring also a hemicolectomy, excision of the fourth portion of the duodenum and cholecystectomy. The pathology report of the excised tumor informs a mesenteric fibromatosis. The patient was discharged at the 18th postoperative day.
