Hyperprolactinemia and Prolactinomas
Endocrinology and Metabolism Clinics of North America, 2008Any process interfering with dopamine synthesis, its transport to the pituitary gland, or its action at the level of lactotroph dopamine receptors can cause hyperprolactinemia. As described in this article, considering the complexity of prolactin regulation, many factors could cause hyperprolactinemia, and hyperprolactinemia can have clinical effects ...

The Epidemiology of Prolactinomas
Pituitary, 2005Prolactin-secreting tumors (prolactinomas), the most frequently occurring pituitary tumor, have a frequency that varies with age and sex. They occur most frequently in females aged 20 to 50 years old, at which time the female-to-male ratio is approximately 10:1.

Malignant prolactinoma is a rare entity and only a few cases have been published. The diagnostic criteria and the clinical course remain unclear. We present a case of malignant prolactinoma in a woman with a 30-year duration of the disease. In the terminal stage of the disease the prolactinoma metastasized to the left eye, the prolactin level reaching ...

SummaryBACKGROUND Apart from the rare association with type I multiple endocrine neoplasia (MEN‐1), familial types of prolactinoma have not been reported.PATIENTS AND MEASUREMENTS Eight hyperprolacti‐naemic patients in four families and 18 of their first and second‐degree relatives (parents, children and grandchildren) were examined.

Pituitary, 2005
In recent years the demonstration that human pituitary adenomas are monoclonal in origin provides further evidence that pituitary neoplasia arise from the replication of a single mutated cell in which growth advantage results from either activation of proto-oncogenes or inactivation of tumor suppressor genes.

Annual Review of Medicine, 1989
Prolactinomas are the most common of the hormone-secreting pituitary tumors and must be distinguished from nonsecreting tumors causing hyperprolactinemia by hypothalamic or stalk dysfunction. For both micro- and macroadenomas, dopamine agonists appear to be the treatment of choice, transsphenoidal surgery being reserved for nonresponders.

Clinical Endocrinology, 1991
The management of prolactinomas requires a complex interaction of medical, surgical and radiotherapeutic intervention. With the judicious use of all these modalities, patients can usually be managed with great success and, perhaps more importantly, their presenting complaints (gonadal dysfunction and infertility) are usually completely corrected.

Annales d'Endocrinologie, 2007
Surgery is generally used as second-line treatment in prolactinomas. For microprolactinomas, it may be indicated in cases of resistance or intolerance to dopamine agonists or where patients prefer definitive cure to lifelong drug treatment. In highly trained hands, selective adenomectomy results in normalization of prolactin levels in 75-90% of cases ...

Journal of Comparative Pathology, 1994
This report describes the incidental finding of an acidophilic adenoma of the pituitary gland in an adult ewe with clinical signs of a nervous disorder. Immunohistochemical examination demonstrated prolactin in the tumour cells, justifying the use of the term "prolactinoma" for the first time in veterinary medicine.

Pituitary, 2005
Prolactinomas are the most frequent pituitary tumors. Treatment of infertility in such tumors usually is very successful. On the other hand, reports of pituitary tumor growth during pregnancy have been described since bromocriptine started to be used.
