title: Familial occurrence of testicular cancer.
abstract: The etiology of testicular cancer is unknown. Familial testicular cancer is a rare entity that adds further information to research regarding the genetic influence on germ cell tumors. We report on 5 brothers, including 2 identical triplets and 1 fraternal brother, with testicular cancer and discuss the epidemiological factors. It appears that environmental and genetic factors must be considered.
