Pure yolk sac ovarian tumor in a young female—Case report with brief review of literature

Abstract

Yolk sac tumors (YSTs) of the ovary are the second most common primitive germ cell tumors accounting for 20% of malignant ovarian germ cell tumors. They are derived from primitive germ cells of the embryonic gonad and can undergo germinomatous or embryonic differentiation. They commonly affect women in the reproductive age group but have a favorable prognosis due to chemosensitivity. This is a case of pure YST of ovary in a nulliparous 25-year-old woman with a past history of endometriotic cysts.
