title: Testicular tumors occurring in non-twin brothers: a case report.
abstract: The present report describes two cases of seminoma that occurred simultaneously in non-twin brothers. These siblings were typed for HLA-A, -B, -C and -DR specificities, and manifested identical haplotypes. Sixty-four sets of affected siblings have been reported prior to the present cases. We examined HLA-DR antigen in brothers with testicular tumors and hereditary roles in the etiology are discussed.
