| eosinophil 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.

| tubular adenoma | <tumour> A benign neoplasm composed of epithelial tissue resembling a tubular gland. (05 Mar 2000) |
| undifferentiated cell adenoma | <tumour> An adenoma of the hypophysis composed of cells for which there is no overt evidence or hormone production, but which usually produces hypopituitarism and visual disturbances by compression of adjacent structures; approximately one third of these tumours have cells with abundant mitochondria (oncocytes) that are somewhat larger than the monocytic null cells. Synonym: undifferentiated cell adenoma. (05 Mar 2000) |
| fibroid adenoma | <oncology, tumour> A benign solid growth, usually found in the breast. (09 Oct 1997) |
| lactating adenoma | <tumour> An uncommon adenoma of the breast composed of tubuloacinar structures with pronounced secretory changes such as seen in pregnancy and lactation. (05 Mar 2000) |
| follicular adenoma | <tumour> An adenoma of the thyroid with a simple glandular pattern. (05 Mar 2000) |
| Fuchs' adenoma | <tumour> A benign epithelial tumour of the non-pigmented epithelium of the ciliary body, rarely exceeding 1 mm in diameter. (05 Mar 2000) |
| Leydig cell adenoma | <tumour> A small benign tumours of the testis that often produce testosterone, causing endocrine symptoms. Synonym: interstitial cell tumour of testis. (05 Mar 2000) |
| acute renal failure | <nephrology> A sudden decline in renal function may be triggered by a number of acute disease processes. Examples include sepsis (infection), shock, trauma, kidney stones, kidney infection, drug toxicity (aspirin or lithium), poisons or toxins (drug abuse) or after injection with an iodinated contrast dye (adverse effect). Chronic renal failure represents a slow decline in kidney function over time. Chronic renal failure may be caused by a number of disorders which include long-standing hypertension, diabetes, congestive heart failure, lupus or sickle cell anaemia. Both forms of renal failure result in a life-threatening metabolic derangement. (27 Sep 1997) |
| aminoaciduria, renal | Impairment of renal tubular transport of amino acids. (12 Dec 1998) |
| back-pressure renal atrophy | <radiology> Caliectasis without obstruction, due to repeated episodes of obstruction, gradual loss of renal pyramids (12 Dec 1998) |
| base of renal pyramid | The outer broad part of a renal pyramid that lies next to the cortex. Synonym: basis pyramidis renis. (05 Mar 2000) |
| branchio-oto-renal syndrome | <syndrome> An autosomal dominant disorder manifested by various combinations of preauricular pits, branchial fistulae or cysts, lacrimal duct stenosis, hearing loss, structural defects of the outer, middle, or inner ear, and renal dysplasia. Associated defects include asthenic habitus, long narrow facies, constricted palate, deep overbite, and myopia. Hearing loss may be due to mondini type cochlear defect and stapes fixation. (12 Dec 1998) |
| capsular branches of renal artery | <anatomy, artery> Branches arising from the renal artery outside of the kidney that are distributed to the renal capsule. Synonym: rami capsulares arteriae renalis. (05 Mar 2000) |
| captopril renal scan | <radiology> In a kidney with a lesion in the afferent arteriole (e.g. Atherosclerotic plaque), reflex constriction of the efferent arteriole occurs through angiotensin system thus maintaining renal perfusion. ACE inhibition prevents constriction of efferent arteriole. Therefore, perfusion is decreased to a kidney with afferent lesions and the renal scan to looks WORSE. Bottom line: renal scans appear WORSE with captopril administration if there is a lesion in the afferent arteriole. See: renal artery stenosis (12 Dec 1998) |
