Extragonadal germ cell tumor followed by metachronous testicular tumor. A case report.
We here present a patient with an extragonadal germ cell tumor followed by a metachronous testicular tumor 7 years later. The histological findings of the extragonadal tumor and the subsequent testicular tumor were quite different; the former was of a mixed type with teratoma, embryonal carcinoma and yolk sac tumor, and the latter a pure seminoma. Such a long clinical time lag as 7 years and the histological differences between the two tumors suggest that they occurred independently. To our knowledge, this may be the first case report in the literature, in which a testicular tumor occurred metachronously after extragonadal tumor extirpation.
