Desmoid tumors are benign but locally aggressive fibrous neoplasms originating from a muscle aponeurosis. Desmoid tumors are finti, nontender overgrowths of fibrous tissue. They may be a feature of tne rare autosomal dominant Gardner [familial adenomatous polyposis (FAP)] syndrome. Their clinical course and the tendency for recurrence make the treatment of these relatively rare fibrous tumors difficult.
