	Prolactinoma - Wikipedia, the free encyclopedia
		A prolactinoma is a benign tumor (adenoma) of the pituitary gland that produces a hormone called prolactin.
		Symptoms of prolactinoma are caused by too much prolactin in the blood (hyperprolactinemia) or by pressure of the tumor on surrounding tissues.
		A woman with a prolactinoma should discuss her plans to conceive with her physician, so she can be carefully evaluated prior to becoming pregnant.

		The size of the prolactinoma correlates with the excess prolactin level; the larger the tumor, the higher the level of prolactin that is secreted.
		Prolactinoma is the most common type of pituitary adenoma and is also referred to as a prolactin-secreting adenoma of the pituitary.
		Surgery may be needed in the case of a prolactinoma that is not controlled by medication, and in patients who have trouble tolerating medication side effects.

		The incidence of prolactinomas is higher in women than in men (this may be due, in part, to the fact that men with this tumor may present much later for clinical evaluation of subtle complaints of hypogonadism e.g.
		Prolactinomas cause symptoms either due to the hormonal effects of excess PRL or due to the space-occupying effects and the pressure which they exert on the pituitary gland and the critical neurovascular structures that surround it such as the optic nerves.
		The use of radiotherapy for prolactinomas has declined in recent years due to the remarkable effectiveness of other treatments such as medications and surgery, hence it is usually reserved for patients who have persistent and progressive symptoms that were not cured by medications or surgery, or patients who cannot tolerate them.

		The signs and symptoms of prolactinoma result from excessive prolactin in your blood (hyperprolactinemia) and, if the tumor is large, from the pressure of a pituitary tumor on surrounding tissues.

	Prolactinoma - New Treatments, January 15, 2005
		Prolactinomas are the most common of the hormone-secreting pituitary tumors.
		The indications for therapy in patients with prolactinomas can be divided into two categories: (1) effects of tumor size and (2) effects of hyperprolactinemia.
		It is unlikely that a prolactinoma will grow significantly with no increase in serum prolactin levels; however, prolactin levels may change significantly.

		In some cases, the prolactinoma will not respond to medication or the patient is intolerant to the medication's side effects; in these cases surgery may be indicated if mass effects of the tumor are a concern.
		If the prolactinoma is small (a microadenoma) and a patient can tolerate the symptoms (breast discharge, etc) and issues of bone loss due to low estrogen are addressed, medication may be optional.
		The "clinical pearl" is to know that large prolactinomas (more than 1 cm) typically cause serum prolactin levels to range from many hundreds to thousands of ng/ml.

	UpToDate Patient information: Lactotroph adenomas (prolactinomas)
		Lactotroph adenomas (prolactinomas) are benign tumors of the pituitary gland that produce prolactin and thereby cause higher than normal blood prolactin concentrations.
		They can cause symptoms either when the high blood prolactin concentration interferes with the function of the ovaries or testicles or, less commonly, when the adenoma grows large enough to compress nearby structures in the head, such as the nerves to the eyes.
		While it is usually very effective in lowering blood prolactin levels, it can cause side effects, including dizziness, nausea, and nasal stuffiness.
