Sporadic Desmoid Tumor of the Small Bowel Mesentery in a Male Patient: A Case Report and Literature Review

Abstract

Aggressive fibromatosis arising from the small bowel mesentery is extremely rare. It may occur in association with previous trauma, abdominal surgery, drugs, Gardner’s syndrome, or familial adenomatous polyposis. This paper presents a 32-year-old man with no significant medical or surgical history, complaining of diffuse abdominal pain and discomfort. His computed tomography scan revealed a well-defined soft tissue mass in the peritoneal cavity. He underwent surgical excision of the mass with resection and anastomosis of the involved loop of the small intestine. Histological examination confirmed mesenteric fibromatosis without infiltration of the bowel. The patient remained well during the 8 months follow-up.
