A Case of Abdominal and Intraabdominal Desmoid Tumors Following Total Rectocolectomy for Familial Adenomatous Polysis (FAP)

Desmoid tumors are rate, benign, locally invasive, and recurrent neoplasms arising from the fascial sheaths and musculoaponeurotic structures. A case of 20-year-old female who developed abdominal and intraabdominal desmoid tumors, 2 years after undergoing total proctocolectomy for familial adenomatous polyposis, was reported. CT scan showed two tumors in the abdominal wall and hydronephrosis of the left kindney. Drip infusion pyelography and retrograde pyelography revealed stenosis of the left ureter, which was caused by a pelvic desmoid tumor. She underwent surgery in June 1996, and two desmoid tumors in the abdominal wall were resected. A small desmoid tumor surrounding the left ureter and four mesenteric desmoid tumors in the abdominal cavity were also resected. Most desmoid tumors appear in females in their reproductive years, often during or after pregnancy. In addition, trauma, especially surgical trauma, has been associated with desmoid tumors. However there are few patients in whom multiple desmoid tumors develop in the abdominal wall and cavity.
