|---|---|
| posterior pituitary | The cleaned, dried, and powdered posterior lobe obtained from the pituitary body of domestic animals used for food by humans; an oxytocic, vasoconstrictor, antidiuretic, and a stimulant of intestinal motility. Synonym: desiccated pituitary, hypophysis sicca. (05 Mar 2000) |
| postpartum pituitary necrosis syndrome | <syndrome> Hypopituitarism arising from a severe circulatory collapse postpartum, with resultant pituitary necrosis. Synonym: postpartum pituitary necrosis syndrome, thyrohypophysial syndrome. (05 Mar 2000) |
| Cushing's pituitary basophilism | <disease> An increased concentration of glucocorticoid hormone in the bloodstream (produced by the adrenal gland) secondary to a pituitary tumour that is secreting the hormone adrenocorticotropic hormone (ACTH). ACTH serves to stimulate the adrenal gland to produce excess glucocorticoids. (27 Sep 1997) |
| hyaline bodies of pituitary | Accumulations of a gelatinous neurosecretory substance in the axons of the hypothalamohypophyseal tract in the posterior lobe of the hypophysis. (05 Mar 2000) |
| desiccated pituitary | The cleaned, dried, and powdered posterior lobe obtained from the pituitary body of domestic animals used for food by humans; an oxytocic, vasoconstrictor, antidiuretic, and a stimulant of intestinal motility. Synonym: desiccated pituitary, hypophysis sicca. (05 Mar 2000) |
| dwarfism, pituitary | A form of dwarfism due to absence or hypofunction of the anterior pituitary gland. (12 Dec 1998) |
| enlarged pituitary infundibulum | <radiology> Histiocytosis X, eosinophilic granuloma, Hand-Schuller-Christian disease, Letterer-Siwe disease, sarcoidosis (12 Dec 1998) |
| acidophil adenoma | <endocrinology, oncology, tumour> A benign tumour, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes. Such pituitary tumours 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 galactorrhoea. (25 Jun 1999) |
| ACTH-producing adenoma | <tumour> A pituitary tumour composed of corticotrophs that produce ACTH, often a basophilic adenoma; may give rise to Cushing's disease or Nelson's syndrome. (05 Mar 2000) |
| adenoma | <oncology, tumour> A benign epithelial tumour in which the cells form recognisable glandular structures or in which the cells are clearly derived from glandular epithelium. (18 Nov 1997) |
| adenoma, adrenal cortical | A benign neoplasm of adrenal cortical cells resembling normal adrenal cells histologically but possessing functional autonomy. In general it does not exceed 5 cm in its largest dimension, although benign tumours exceeding 20 cm have been reported. Adrenal cortical adenomas produce hypercortisolism and hyperaldosteronism, but seldom produce adrenogenital syndromes. For the most part the prognosis after surgery is reasonably favourable. (12 Dec 1998) |
| adenoma, basophil | A small tumour of the anterior lobe of the pituitary gland whose cells stain with basic dyes. It may give rise to excessive secretion of acth, resulting in cushing's syndrome. (12 Dec 1998) |
| adenoma, bile duct | A benign tumour of the intrahepatic bile ducts. (12 Dec 1998) |
| adenoma, chromophobe | A tumour of the anterior lobe of the pituitary gland whose cells do not stain readily with either acid or basic dyes and whose presence may be associated with hypopituitarism. Although classically these adenomas have been said to be composed of sparsely granulated or degranulated (nonfunctioning) cells, some contain functioning cells and may be associated with a hyperpituitary state, e.g., acromegaly or cushing's syndrome.
