| papillary muscle syndrome | Impaired function of a papillary muscle, usually due to ischemia or infarction, with resulting incompetence of the mitral valve. Synonym: papillary muscle syndrome. (05 Mar 2000) |

| papillary necrosis | <radiology> Mnemonic: POST CARD, P pyelonephritis, O obstruction, S sickle cell disease, T TB, C cirrhosis (EtOH), A analgesics (phenacetin and aspirin), R renal vein thrombosis, D diabetes (12 Dec 1998) |
| papillary process | The left lower angle of the caudate lobe of the liver, opposite the caudate process. Synonym: processus papillaris. (05 Mar 2000) |
| papillary stasis | An obsolete term for papilledema. (05 Mar 2000) |
| papillary tumour | A tumour shaped like a small mushroom with its stem attached to the inner lining of the bladder. (12 Dec 1998) |
| renal papillary necrosis | <nephrology> Necrosis of renal papillae, occurring in acute pyelonephritis, especially in diabetics, or in analgesic nephropathy; renal failure may result. Synonym: necrotizing papillitis. (05 Mar 2000) |
| cystadenocarcinoma, papillary | An adenocarcinoma in which the tumour elements are arranged as finger-like processes or as a solid spherical nodule projecting from an epithelial surface. (12 Dec 1998) |
| cystadenoma, papillary | A benign neoplasm of the ovary. (12 Dec 1998) |
| inflammatory papillary hyperplasia | Closely arranged papules of the palatal mucosa underlying an ill-fitting denture. Synonym: palatal papillomatosis. (05 Mar 2000) |
| intravascular papillary endothelial hyperplasia | A benign florid papillary endothelial proliferation within the veins of the skin or subcutis, less often in visceral blood vessels. Synonym: Masson's pseudoangiosarcoma. (05 Mar 2000) |
| kidney papillary necrosis | A form of acute kidney disease characterised by necrosis of the renal papillae. It is most frequently associated with diabetes mellitus because of the severe vascular disease present in the arteries and capillaries, particularly in the kidney. There is usually a large component of infection present, and in non-diabetics pyelonephritis and obstructive uropathy are the usual aetiologic agents. (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.
