Testicular malignancy in father and son. A case report

The etiology of testicular cancer is unknown, but both environmental and genetic factors have to be considered. The recognition of the tumour in more than one member of a family, a rare occurrence, adds further material to the research of the etiology and might, therefore, be of general interest. To the few cases of testicular cancer occurring both in father and son reported in the literature, the present presentation adds another instance of embryonal metastasizing cancer.
