Abstract
We report 2 cases of sporadic mesenteric fibromatosis with a review of the literature. Case 1 : A 48-year-old woman came to our hospital complaining of a left lower abdominal mass. A 9-cm-diameter tumor was detected by CT scan.
She underwent resection of the tumor. The tumor was located in the mesentery of the jejunum. Case 2 : A 24-year-old woman came to our hospital complaining of a left lower abdominal mass. A 6-cm-diameter tumor was identified by CT scan and MRI. Laparotomy revealed that the tumor was located in the mesentery of the sigmoid colon and adhered to the mesentery of the ileum. We performed partial resection of the sigmoid colon and the ileum. These tumors were histologically diagnosed as mesenteric fibromatosis. These patients survived without recurrence for 6 years (Case 1) and 1 year 4 months (Case 2) after surgery. Mesenteric fibromatosis is very rare in a patient without a family history of Gardner's syndrome or past history of abdominal surgery or trauma.
