Overview
Ovarian germ cell tumor may be benign or malignant. Each category sub classified to different types based on histologic features.
Classification
Ovarian germ cell tumor may be classified into two subtypes of benign and malignant tumors. Benign tumors are comprised of only teratoma, however, the malignant germ cell tumors may be classified to different types according to the histologic features.
- Teratoma[1]
- Mature cystic teratomas (dermoid cysts)
- Immature teratoma
- Monodermal teratoma
- Dysgerminoma
- Yolk sac tumor
- Mixed germ cell tumors
- Pure embryonal carcinoma
- Non-gestational choriocarcinoma
- Pure embryoma
WHO Classification of Ovarian Tumors
WHO classifies ovarian germ cell tumors as follows:[2]
- Teratoma
- Immature
- Mature
- Solid
- Cystic (dermoid cyst)
- Dysgerminoma
- Endometrial Sinus tumors
- Embryonal carcinoma
- Polyembryoma
- Choriocarcinoma
- Mixed germ cell tumors
