Familial germ cell tumor.

Familial testicular germ cell tumors are well known in literature. Only few cases are reported where both brother and sister of the same family suffered from germ cell malignancies. We present a family where the proband is a survivor of ovarian dysgerminoma stage IA. Her elder male sibling became acutely ill and was detected to have disseminated testicular malignancy with grossly elevated markers and vegetations in the mitral valve leaflets. Despite all measures he could not be saved. Presence of germ cell malignancies in the siblings of different sex in the same family points toward a genetic susceptibility. Literature review revealed only six similar cases. A discussion regarding the rare occurrence of familial germ cell malignancies with the affected family members may be worthwhile.

Ataxia telangiectasia: Family management.

Ataxia telangiectasia (AT) is a rare autosomal recessive disease resulting in progressive degeneration of multiple systems in the body. Both A-T homozygote and heterozygote are at increased risk of developing malignancy. We report a family in which three generations were affected by this disorder. Our index case is a 12-year-old female child, born of second degree consanguineous marriage diagnosed to have ataxia telangiectasia at the age of four years, now presented with fever and neck swelling of one month duration. Family history suggestive of ataxia telangiectasia in maternal uncle and younger sibling was present. History of premature coronary artery disease and death in paternal grandfather was present. On evaluation, child was diagnosed to have Alk negative anaplastic large T cell lymphoma. Management included genetic counseling, examination of all the family members, identification of A-T homozygote and providing appropriate care, regular surveillance of the heterozygote for malignancy.
