Abstract
Ovarian teratomas are tumors resulting from pluripotent germ cells. We here describe 3 different types of teratomas: mature, immature and monodermal teratomas. Immature teratoma accounts for less than 1% of ovarian cancers and mainly affects young subjects. We report the case of a 25 year female patient, admitted with abdomino pelvic mass. She underwent ultrasound and a pelvic CT scan followed by conservative treatment based on left annexectomy associated with multiple biopsies. Anatomopathological examination showed immature ovarian teratoma. Patient's treatment was supplemented by a hysterectomy with lumbo-aortic curage and omentectomy. We highlight, through this study and review of the literature, the predisposing factors for this type of rare and severe tumor and the radiological features suggesting these rare histological types of ovarian tumors, in order to improve the prognosis and multidisciplinary management of patients.Entities:
