Mesenteric fibromatosis as an irreducible inguinal hernia.

We present the case of a man in his 60s with hypertension, who had a 3-year history of an irreducible mass in the left inguinal area. The patient presented at the emergency room with left lower quadrant pain and scrotal pain. The clinical examination was not suggestive of an acute abdomen. A CT scan was done showing an anterior abdominal wall defect at the left inguinal region. The patient underwent exploratory laparotomy, ileal resection and anastomosis, mesh hernioplasty left for the mesenteric fibromatosis mass mimicking as an irreducible inguinal hernia. Histopathology and immunohistochemistry showed desmoid-type fibromatosis.
