title: Histologically similar testicular neoplasms occurring in brothers.
abstract: Testicular malignancies occur rarely in closely related family members. Two young adult brothers are described who had histologically similar seminomas in the right testis. To my knowledge this is the tenth set of testicular tumors and the third set of histologically similar cell type seminomas reported in non-twin brothers.
