IMMATURE OVARY TERATOMA

A CASE REPORT

Abstract

Immature ovarian teratoma consists of a tumor formed by tissues from the three germinal layers: ectoderm, mesoderm and endoderm, containing immature or embryonic structures. It is an uncommon tumor and comprises less than 1% of ovarian tumors, being the second most common germ cell tumor. This neoplasm is more common in the first three decades of a woman’s life. May present with a pelvic mass, or in the form of abnormal uterine bleeding or pelvic pain. Early diagnosis associated with immediate therapy and strict follow-up are essential for a favorable longterm outcome, especially in relation to the preservation of the patient’s reproductive future. The present case report presents a 24-year-old female patient with a large mass in the left ovary with omental infiltration, who was submitted to anatomopathological and immunohistochemical studies that showed an immature ovarian teratoma.
