title: Immature teratoma with choriocarcinoma-like lesion of testis: case report of an unusual presentation.
abstract: An eighteen year old male presented with hemoptysis and superior vena caval syndrome. History and clinical examination revealed a testicular mass which was previously diagnosed as hematocele. Chest x-ray showed a four cm diameter shadow and several smaller shadows. Histological examination of the testicular mass established it as immature teratoma with choriocarcinoma-like lesion (CCLL)--a rare association in testicular tumours. Focal positivity for betaHCG was noted in the testicular tumour. Guided aspiration of the lung showed features of a metastatic non seminomatous germ cell tumour.
