A Rare Case of Large Nasal Teratoma Associated with Congenital Heart Anomalies in a Neonate

Sacrococygeal teratomas are the most common teratomas, while head and neck cases are extremely rare[1, 2]. The approximately reported incidence of teratoma is 1 in 35000 to 40000 live-births[3, 4]. Although they are generally more common in females, no gender preference is reported in head and neck ones[2]. It is thought that teratoma originates from those multi-potential germinal cells which are lost during a migration from yolk sac endodermal layer adjacent to allantois to gonadal edge in fourth and fifth gestational week[5]. The mentioned cells then can be arisen as teratoma somewhere from brain to coccyx, often in the midline[
