A non-seminomatous germ cell tumor arising from the ovary. It is characterized by the presence of various tissues which correspond to the different germinal layers (endoderm, mesoderm, and ectoderm). According to the level of differentiation of the tissues which comprise the tumor, ovarian teratomas are classified as mature or immature. Mature teratomas are composed of well differentiated, adult-type tissues. Immature teratomas are composed of immature, fetal type-tissues. Mature ovarian teratomas without a fetal-type component have an excellent outcome. The prognosis of immature ovarian teratomas is related to the grade and stage of the tumor.
Biomarker and diagnostic research for ovarian teratoma has been reported in the published literature.
1 clinical trial registered. Interventions under study include drug therapy, other interventions, procedural interventions, and biologic therapy. Pipeline includes 1 PHASE3. Research is primarily sponsored by academic and government institutions.
286 publications have been identified in PubMed for ovarian teratoma. Research spans Case Report / Case Series (66%), Review / Meta-Analysis (9%), and Epidemiology / Natural History (7%).
