title: Sarcomatous change in a teratoma after treatment of testicular carcinoma.
abstract: Treatment can transform the metastases of nonseminomatous germ cell carcinoma into histologically mature teratoma. These lesions typically have a benign clinical course. The authors present a case of leiomyosarcoma occurring within such a lesion. It arose 18 years after therapy for metastatic embryonal carcinoma of the testis and appears to have been radiation induced.
