Desmoid tumors of the chest wall.

Chest wall desmoid tumors (DT) are rare pathologic entities with microscopic features similar to, or undistinguishable from, fibromas or fibrosarcomas. From 1996 to 2001, four patients with DT were surgically managed in our department. Their ages ranged from 27 years to 43 years (mean 32.25 years, median 29.5 years). A resection of the lesion was performed with negative margins of 4 cm around the tumor (wide resection). A reconstruction of the chest wall was also performed with polytetrafluoroethylene (PTFE) in 2 patients and methylmethacrolate with Marlex mesh in 1 patient. One patient had a recurrence 15 months later, and was admitted for complementary resection, and remains disease-free for 5 years. The rest 3 patients are disease-free for 6 months to 5 years. Resection must include all adjacent, overlying and underlying musculature as well as soft tissues and any spare skin from the procedure should be used. Prognosis after a wide resection is good.
