What tumor causes amenorrhea,galactorrhea,hirsutism,and osteopenia?

Question

Quizplus · Accepted Answer

Prolactinoma is a type of pituitary adenoma that causes increased production of prolactin hormone. This can lead to a variety of symptoms including amenorrhea (absent or irregular menstrual periods), galactorrhea (abnormal breast milk production), hirsutism (excessive hair growth) and osteopenia (low bone density). Thymoma is a tumor of the thymus gland and is not known to cause these symptoms. Growth hormone adenoma can cause acromegaly (enlargement of hands, feet and facial bones) but not the symptoms listed. Posterior pituitary adenoma can also cause hormonal imbalances, but not necessarily with the same symptoms as a prolactinoma.
