A Giant Immature Teratoma of the Ovary in 18-Years Old Girl (A Case Report with Uncommon Presentation and Review of the Literature) - Abstract
Teratoma is a tumor usually seen in children and adolescents and is composed of a mixture of embryonal and adult tissues derived from all three
germ layers: ectoderm, mesoderm, and endoderm. According to the current WHO grading system classification of the tumor consists of mature/benign and
immature/malignant, depending on the presence and abundance of immature component [1,2,11,12].
The size and stage correlate to the survival. The microscopic grade of the primary tumor best determines the likelihood of extra-ovarian spread and the
grade of the metastases correlate best with the subsequent course. Indeed, a thorough tumor sampling is necessary for accurate grading. Here we report a
case of high-grade immature teratoma in an 18-year-old girl.
