A submandibular endodermal sinus (yolk sac) tumor (EST-YST) is reported. The patient was a 1.5-year-old girl exhibiting a rapidly growing tumor in the submandibular region. The lesion showed the typical microscopic features including Schiller-Duval bodies and colloid bodies. Alpha-fetoprotein immunoreactivity was expressed by most tumor cells. There was no clinical or radiological evidence of the presence of this tumor elsewhere in the body.
