title: Alveolar soft part sarcoma following radiotherapy for a spinal hemangioma. A case report.
abstract: A case of alveolar soft part sarcoma arising some 20 years later in a site previously irradiated as a treatment for a spinal cord hemangioma is described. This is the first known case of radiation-associated alveolar soft part sarcoma, and it fulfills the criteria for a tumor to be radiation-induced. The coincidental finding of "viral-like" particles within some of the tumor cells was noted.
