Recurrent ‘growing teratoma syndrome’ in an adolescent girl with a history of ovarian immature teratoma: A case report*

Abstract

The incidence of ovarian tumours in girls has been estimated as 2.6/100,000 cases annually, and malignant ovarian tumours coincide in about 1% of all childhood cancers. (Al Jama et al. 2011).About 70% of ovarian tumours derive from germ cells during adolescence, and approximately, one-third of them have malignant potential (Low et al.2012). The most common type of benign germ cell tumour is mature cystic teratoma, also called dermoid cyst, and the most common type of malignant germ cell tumour is dysgerminoma.
