[Peripheral neuroectodermal tumor of the thoracic wall. Experiences with surgical treatment].

The peripheral neuroectodermal tumor (PNET) is seen nowadays as a more specified form of Ewing's Sarcoma with a worse prognosis. We report our experiences of three children (10-14 years old) with PNET of the right thoracic wall, all treated surgically within 1 year. Complete local resection-the main aspect of PNET therapie-of the initially voluminous tumors was not difficult due to chemotherapy and radiotherapy for 5 months prior to surgery.
