Germ cell tumors account for less than 3% of all ovarian cancers. These tumors generally appear in childhood or in those under 30 years of age. Immature ovarian teratoma is the third most frequent germ cell tumor after dysgerminoma and endodermal sinus tumors. These tumors should be distinguished from mature teratomas. Discrimination of malignant and benign tumors depends on the presence of the neuroectodermal components, made up of neural and glial cells. Gliomatosis peritonei is the intraabdominal and particularly peritoneal and omental distribution of the neuroectodermal components, observed very rarely with immature teratoma. Mature teratoma, on the other hand, is even rarer. This report aims to discuss a case of immature teratoma completely filling the abdomen and concomitant omental distribution related gliomatosis peritonei in a 7-year-old child.
