Abstract

Abstract: Growing teratoma syndrome (GTS) is a condition in which mature teratoma with negative tumor markers arises at the site of a treated malignant germ cell tumor. Pathogenic variants in PTEN have been reported to cause autosomal dominant cancer predisposition syndromes and are associated with germ cell tumors. We report the association of a novel heterozygous pathogenic variant in PTEN and very early onset ovarian germ cell tumor complicated by GTS as well as overgrowth syndrome. This marks the youngest reported patient to have developed GTS following treatment of her primary malignant ovarian germ cell tumor.
