Yolk sac tumor of cryptorchid testis diagnosed by fine needle aspiration cytology

Abstract

Yolk sac tumor is the most common germ cell tumor in infants and children. Majority of them arise in the gonads. Yolk sac tumor of undescended testis has been rarely diagnosed. We present a case of yolk sac tumor in right undescended testis in a 2-year-old child primarily diagnosed by fine needle aspiration cytology.
