Prolactin-producing pituitary adenoma in a 9 year old boy. 1979

W Beck, and P Stubbe, and D Lüdecke

A boy aged 9 years and 8 months was evaluated for headache and an enlarged sella. His neurological status and visual fields were normal. After injection of radiographic contrast agent, computerized axial tomography showed evidence of an intrasellar tumor. The most striking endocrine abnormalities were growth hormone insufficiency after arginine infusion and after insulin-induced hypoglycemia, and excessively elevated prolactin levels ranging between 1220 ng/ml and 1560 ng/ml. A slightly granulated, acidophilic pituitary adenoma was selectively removed by the trans-sphenoidal approach. The function of the anterior pituitary improved post-operatively. Growth hormone secretion after insulin-induced hypoglycemia returned to normal, and the basal serum prolactin levels decreased, but are still three times higher than normal.

D010911	Pituitary Neoplasms	Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.

D011388	Prolactin	A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.

D000239	Adenoma, Acidophil	A benign tumor, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes. Such pituitary tumors may give rise to excessive secretion of growth hormone, resulting in gigantism or acromegaly. A specific type of acidophil adenoma may give rise to nonpuerperal galactorrhea.
