Up to 64% are neoplastic of which the large majority are germ cell tumours (GCT) (60-80%). Sex cord stromal cell tumours and surface epithelial tumours account for 5% and <20% respectively unlike in adult ovarian tumours where surface epithelial tumours predominate.enIn House PublicationsOvarian massesChildrenOvarian tumoursCancersGerm cell tumours (GCT)Ovarian cysts and tumours in children and adolescentsArticle
