A case of yolk sac tumor of the vagina in an infant.

We report a case of a vaginal yolk sac tumor in a 5-month-old female infant who presented with short history of bleeding per vagina. Magnetic resonance imaging showed a mass occupying most of the vagina that had lobulated outlines and heterogeneous echo texture. The serum alpha-fetoprotein was elevated, and a biopsy revealed a vaginal yolk sac tumor. The patient was given six cycles of chemotherapy and continues to be disease-free on follow up. To preserve sexual and reproductive function, we encourage consideration of chemotherapy as a sole modality to treat this rare tumor.
