[An autopsy case revealing bilateral successive testicular germ cell tumors of different cell types].

A 28-year-old man, evidencing a painless swelling of the right scrotal content, was admitted and, after a diagnosis of a right testicular tumor, a right high orchiectomy was performed. A histological examination of the right testicular tumor revealed a seminoma. Eleven months after this operation, the patient returned, complaining of a painful swelling of the left testis. An examination revealed that his alpha-fetoprotein (AFP) was elevated (3319 ng/ml). A left high orchiectomy was performed after he was diagnosed as a non-seminomatous tumor. Later, a histological examination revealed, however, an embryonal carcinoma. Two months after the second operation, a metastases of right supra-clavicular lymph nodes was uncovered and adjuvant chemotherapy was started. Although he died from the progression of this metastases, at autopsy, the retroperitoneal and para-aortic metastatic lymph nodes revealed a mature teratomatous and embryonal carcinoma.
