Successful use of intraoperative radiotherapy for local control of an Askin's tumor recurrence.

Askin s tumor is an infrequent disease, with a high tendency to local recurrence. We present the case of a 16-year-old female diagnosed with a new recurrence of this tumor affecting the thoracic wall. There had been a previous 5-year history of 3 local recurrences treated each time by apparently complete surgery. A multidisciplinary approach consisting of chemotherapy, complete chest tumor resection and intraoperative radiotherapy was undertaken. After 2-year follow-up, the patient is alive and free of disease. The role of surgery is still the key to obtaining good survival, but in this case intraoperative radiotherapy proved to be a good adjuvant treatment.
