title: Bilateral successive testicular cancer of different cell types.
abstract: The fourth case of bilateral successive testicular tumors of different cell types is reported (seminoma and embryonal carcinoma), and the English literature on bilateral testicular tumors from 1965 to 1975 is reviewed. The absence of direct organ extension or demonstrable metastatic lymphatic or vascular involvement points to the primary origin of these lesions.
