ABSTRACT
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.

Testicular tumors account for 1% of all cancers in men and it occurs in 1 in 500 men. Incidence of familial testicular tumours is rare. Total number of cases till the year 1992 in identical twins is 21, in brothers 82 and father-son both affected in 31 pairs. We report a case of two brothers presenting simultaneously with testicular tumours. Both were subjected to retrograde orchidectomy. Histopathologic examination of one revealed embryonal cell carcinoma and other mature teratoma of the testis. Patient with embryonal carcinoma was given adjuvant chemotherapy based on Bleomycin, Etoposide and cisplatinum (BEP) and one with mature teratoma was put on a follow up.
