Abstract

Endodermal sinus tumor (EST) is a rare malignant germ cell tumor arising usually in the gonads such as the testis or ovary. However, 10-15% of EST cases may arise in the extragonadal sites, such as sacrocoxygeal area, mediastinum, vagina, brain and retroperitoneum in a frequent occurring order. To our knowledge there are only 2 case reports of extragonadal EST, one originating from the omentum in 1998, and another which was localized in the pelvis in 2003. We report one case of extragonadal sinus tumor which arose in appendix and mesentery in the 19-year-old female with a review of the literature.
