A Case of Endodermal Sinus Tumor of the Pineal Gland

Endodermal sinus tumor is characterized by perivascular structures(Schiller-Duval bodies). which simulate endodermal diverticula of yolk sac origin. Endodermal sinus tumor has generally been reported to be in ovary and testis. Very few cases of endodermal sinus tumor originating from extragonadal sites such as mediastinum, pelvis, vagina, sacrococcygeal region, pineal gland have been described. The authors report a case of endodermal sinus tumor arising from pineal gland and briefly review literatures.
