What are the types of germ cell tumors found in the ovaries?

Germ cell tumors in the ovaries originate from the specialized cells that give rise to eggs or oocytes. The main types of germ cell tumors include dysgerminomas and yolk sac tumors.

Dysgerminomas are analogous to testicular seminomas and are the most common malignant germ cell tumor found in women. They typically occur in young women and can present with elevated levels of serum lactate dehydrogenase (LDH).

Yolk sac tumors, also known as endodermal sinus tumors, are another type of germ cell tumor that can occur in the ovaries. They often produce alpha-fetoprotein (AFP) as a tumor marker and can occur at any age, although they are more common in younger women.

The other answer choices pertain to different classifications of tumors. For instance, granulosa cell tumors and Sertoli-leydig tumors are thought to arise from sex-cord stromal cell origins rather than germ cell origins. Serous and mucinous tumors, on the other hand, are types of epithelial ovarian tumors, while endometrioid tumors are classified separately and are characterized by a different pathogenesis linked to endometriosis.

In summary, the identification of dysgerminoma
