Down’s Syndrome Associated with Intracranial Germinoma and Testicular Embryonal Carcinoma

Abstract

In patients with Down's syndrome, the frequency of leukemia is significantly greater than normally would be expected. However, cancers other than leukemia have been reported to occur rarely. We present a case of Down's syndrome associated with intracranial germinoma and testicular embryonal carcinoma. Currently, no case of double primary carcinomas in Down's syndrome has been reported to the authors' knowledge.
