Abscess formation in desmoid tumors of Gardner's syndrome and percutaneous drainage: a report of three cases.

PURPOSE: To describe abscess formation complications in desmoid tumors of patients with Gardner's syndrome and percutaneous drainage. METHODS: Three patients with Gardner's syndrome and intramesenteric desmoid tumors were diagnosed as having intratumor abscess formation. Percutaneous drainage was the initial method of treatment in each case. Two subsequently underwent surgical resection and one patient refused surgery and was lost to follow-up. RESULTS: In each case, percutaneous drainage and antibiotics resulted in clinical improvement. In two, fistulous communication with the small bowel could be demonstrated, presumed to be the cause of abscess formation. Surgical resection confirmed fistula communication to the small bowel. In the third patient, no fistula was seen and only percutaneous drainage was performed. CONCLUSION: Abdominal pain and fever in patients with Gardner's syndrome and desmoids is suggestive of abscess formation in these tumors. Percutaneous drainage is useful as initial management.
