prolactinoma

prolactinoma
SYN: prolactin-producing adenoma.

* * *

n.
a benign tumour (an adenoma) of the pituitary gland that secretes excessive amounts of prolactin. Symptoms include a loss of sexual drive, amenorrhoea or impotence, and sometimes production of milk from the nipples of both men and women. If the tumour is large enough it may compress and damage adjacent structures. Treatment is with dopamine receptor agonist drugs, such as bromocriptine, as dopamine inhibits prolactin production and may also shrink and harden the tumour, facilitating later surgical removal.
