| hypertrophic interstitial neuropathy | Sensorimotor neuropathy characterised pathologically by collections of Schwann cell processes arranged concentrically around one or more nerve fibres. No genetic factors are known in its aetiology.For hereditary types, see hereditary hypertrophic neuropathy. (05 Mar 2000) |

| hypertrophic osteoarthropathy | <radiology> Pulmonary, malignancy (bronchogenic carcinoma, lymphoma, metastasis), abscess, COPD / bronchiectasis, pleural, pleural fibroma (highest incidence of HOA, tho' rare itself), mesothelioma, cardiac, cyanotic congenital heart disease, GI, inflammatory disease (Crohn, UC), malabsorption (dysentery, lue, cirrhosis), ** causes symmetrical periosteal reaction (12 Dec 1998) |
| hypertrophic rhinitis | Chronic rhinitis with permanent thickening of the mucous membrane. (05 Mar 2000) |
| hypertrophic rosacea | A manifestation of severe acne rosacea resulting in significant enlargement of the nose and occurring primarily in men. It is caused by hypertrophy of the sebaceous glands and surrounding connective tissue. The nose is reddened and marked with numerous telangiectasias. (12 Dec 1998) |
| hypertrophic scar | An elevated scar resembling a keloid but which does not spread into surrounding tissues, is rarely painful, and regresses spontaneously; collagen bundles run parallel to the skin surface. (05 Mar 2000) |
| osteoarthropathy, primary hypertrophic | A conditioned chiefly characterised by thickening of the skin of the head and distal extremities, deep folds and furrows of the skin of the forehead, cheeks, and scalp, seborrhoea, hyperhidrosis, periostosis of the long bones, digital clubbing, and spadelike enlargement of the hands and feet. It is more prevalent in the male, and is usually first evident during adolescence. It is believed to be inherited as an autosomal dominant trait. (12 Dec 1998) |
| osteoarthropathy, secondary hypertrophic | Symmetrical osteitis of the four limbs, chiefly localised to the phalanges and the terminal epiphyses of the long bones of the forearm and leg, sometimes extending to the proximal ends of the limbs and the flat bones, and accompanied by dorsal kyphosis and joint involvement. It is often secondary to chronic conditions of the lungs and heart. (12 Dec 1998) |
| familial hypertrophic cardiomyopathy | Familial occurrence of hypertrophic cardiomyopathy exhibiting an autosomal dominant pattern of inheritance. Familial cardiomyopathy of various kinds occurs with autosomal dominant inheritance. There is also an asymmetrical form affecting the ventricles and the interventricular septum. (05 Mar 2000) |
| aortic stenosis | Progressive narrowing of the aortic valve resulting in the obstructed passage of blood from the left ventricle into the aorta. Causes for aortic stenosis include rheumatic fever, congenital and idiopathic sclerosis. Chronic stenosis can lead to left ventricular enlargement and congestive heart failure. (27 Sep 1997) |
| aortic valve stenosis | Narrowing of the orifice of the aortic valve or of the supravalular or subvalvular regions. (12 Dec 1998) |
| aqueductal stenosis | <radiology> most common cause of congenital hydrocephalus (43%), aqueduct develops about the 6th week of gestation, M:F = 2:1, other congenital anomalies (16%): thumb deformities, prognosis: 11-30% mortality aetiology: infectious (50%): toxoplasmosis, CMV, syphillis, mumps, influenza, developmental: forking, narrowing, transverse septum (X-linked recessive), neoplastic (extremely rare): glioma, pinealoma, meningioma (12 Dec 1998) |
| buttonhole stenosis | Extreme narrowing, usually of the mitral valve. (05 Mar 2000) |
| calcific nodular aortic stenosis | Most common type of aortic stenosis, occurring usually in elderly men, in which the cusps contain calcified fibrous nodules on both surfaces; the causes include rheumatic fever, atherosclerosis, age-related degeneration, and congenitally bicuspid aortic valve. (05 Mar 2000) |
| valvular aortic stenosis | <radiology> Secondary to fusion of commisures between cusps types: bicuspid/unicuspid (95%): in 1-2% of population; M>F; commonly associated with coarctation, tricuspid (5%), dysplastic thickened aortic cusps in infants with crtical aortic stenosis: may stimulate neonatal sepsis, associated with L-R shunts (atrial septal defect, VSD), marked CMG (thickened wall of LV), pulmonary venous hypertension, congestive heart failure child/adult: LV configuration with normal heart size, postenotic dilatation, calcified valve (60% of patients greater than24 y.o.) see: aortic stenosis (12 Dec 1998) |
| carotid stenosis | The narrowing or stricture of a carotid artery that may lead to transient ischemic attacks (see cerebral ischemia, transient) and stroke (see cerebrovascular disorders). (12 Dec 1998) |
