FNAC diagnosis of yolk sac tumor: a case report.

ABSTRACT

Yolk sac tumor is the second most common germ cell tumor of the ovary. A nine year old female child presenting with a lower abdominal mass diagnosed as a yolk sac tumor on fine needle aspiration cytology (FNAC) is described. Ultrasonographically (USG) guided FNAC of the lesion revealed tight clusters and papillary fronds of cells associated with homogeneous acellular eosinophilic bodies. A preoperative diagnosis of this tumor is helpful in planning further diagnostic and therapeutic steps.
