Familial Testicular Teratoma in 2 Children: Familial Report and Review of the Literature

Abstract

Familial occurrence of a testicular tumor is rare. Mature teratomas in 2 first cousins are reported in a consanguineous family. The cases were unique because both tumors were pathologically similar and their onsets were close. Of 34 families with testicular neoplasms reviewed this is the 1st family composed of 2 affected children with mature tertomas. The analysis of the familial cases showed segregation of twins and a slightly higher incidence of bilateral tumors. The genetic roles are discussed in the etiology of testicular tumor.
