[Neuroblastoma arising in testicular teratoma]

Abstract

One case of neuroblastoma arising in an adult immature testicular teratoma is described, with multiple systemic metastases, a partial response to intensive chemotherapy and a swift recurrence leading to death. Such instances of prevailing neuroblastoma with systemic metastases, have only seldomly been reported hitherto. Because of the teratoma and the focal presence of intratubular germ cell neoplasia of unclassified type, we think this tumor must be indeed of germ cell derivation.
