Classic signs of an anterior pituitary adenoma include which of the following?

Explanation:
Cessation of menses is most characteristic because a prolactin-secreting pituitary adenoma raises prolactin levels, which inhibits the hypothalamic GnRH pulse generator. That suppression lowers LH and FSH, leading to anovulation and amenorrhea. While galactorrhea (milk production) can occur with high prolactin, amenorrhea is the more consistently described classic sign in women with an anterior pituitary adenoma. Other signs like changing facial features point to different tumors (such as GH excess causing acromegaly), and weight gain is not a specific hallmark of a pituitary adenoma.
