Cysts arising from the cortex of the ovary are termed what?

• A. Surface epithelial cyst
• B. Theca lutein cyst
• C. Granulosa cell tumor
• D. Dermoid cyst

Answer: (A)

Cysts that originate from the surface covering of the ovary are called surface epithelial cysts. The outer layer of the ovary, including the cortex, is lined by ovarian surface epithelium; when cysts arise from this lining, they’re categorized as surface epithelial cysts (the most common type in adults, including serous and mucinous cystadenomas). Theca lutein cysts come from the theca interna cells of follicles and are usually hormonally driven; granulosa cell tumors are solid neoplasms from granulosa cells; dermoid cysts are mature cystic teratomas from germ cells.
