Sporadic desmoid tumors of the abdominal wall: the results of surgery.

Purpose: Before the wait-and-see policy became the standard approach in abdominal wall desmoid tumors, surgery was performed on a systematic basis. Surgery remains indicated for progressing tumors but its extent is debatable. The abdominal wall is a common site of origin of sporadic desmoids, usually associated with a favorable prognosis.

Atypical lipomatous tumors: should they be treated like other sarcoma or not? Surgical consideration from a bi-institutional experience.

Background: To identify the best surgical approach to atypical lipomatous tumors we reviewed 171 patients who underwent surgery at two sarcoma referral centers with different surgical policies.

Methods: Of the 151 patients (88 %) with primary tumors, 95 were treated at Institution A and 76 were treated at Institution B. At Institution A, a wide surgical resection, including a slight cuff of soft tissue around the mass, was adopted, which was defined as marginal resection (MR) according to the Enneking classification.
