title: Extragonadal yolk sac tumor of the head and neck region: A report of two cases.
abstract: Extragonadal germ cell tumors (EGCTs) are rare and head and neck is a rarer primary site with most tumors being benign exhibiting teratoma as the leading histologic type. Yolk sac tumor (YST) is relatively uncommon in this location; most commonly described in association with a teratoma and rarely solo. We report two male children, aged 1 year 7 months and 3 years 5 months, with YST involving the head and neck region.
