Vaginal Yolk Sac Tumor in an Infant.

Yolk sac tumors are most common tumors among the germ cell tumors (GCTs) in children, mostly involving the gonads. But yolk sac tumors involving the vagina are very rare. These usually present with per vaginal bleeding and vaginal mass. Presentation with discharged tumor fragments is very unusual. We present a rare case of yolk sac tumor of vagina in an infant with very unusual presentation of per vaginal tumor tissue discharge, histopathological examination of which was diagnostic.
