The most common primary ovarian neoplasm? arising from the wall of a follicle

• A. Cystic teratoma, dermoid
• B. Serous cystadenoma
• C. Mucinous cystadenoma
• D. Granulosa cell tumor

Answer: (A)

The idea being tested is the origin of certain ovarian tumors from the follicle structure. A granulosa cell tumor arises from the granulosa cells that line the wall of the ovarian follicle, placing it squarely in the category of tumors that originate from the follicular wall. This makes it the best fit for the stem that specifies a neoplasm arising from the follicle’s wall. In contrast, cystic teratomas (dermoid) come from germ cells and are the most common ovarian neoplasm in younger patients but do not originate from the follicle wall. Serous and mucinous cystadenomas originate from the ovarian surface epithelium, not from the follicle wall. Hence, they don’t match the described location of origin.
