title: Tumors of the testis in two brothers: a case report.
abstract: This paper describes two nontwin brothers with a nonseminoma tumor of a testicle: an embryonal carcinoma in one and an embryonal carcinoma with seminomatous components in the other. Testicular tumors of the same type have the same frequency in twin brothers as in nontwin brothers. For the present, there is no insight into the genetic influence in the pathogenesis of testicular tumors.
