OVARIAN TERATOMA IN A GREEN IGUANA (IGUANA IGUANA)

Abstract

An ovarian mass was diagnosed in an adult female green iguana {Iguana iguana) by ultrasonography during evaluation for ovarian follicular development. A large, well-circumscribed, hypervascular ovarian mass with multiple fluid-filled vesicles was identified during surgery. A histopathologic diagnosis of ovarian teratoma was made based on the presence of multiple tissues of different embryonic germ-layer origins. The teratoma recurred as a malignant tumor 18 mo later.
