| cicatrix, hypertrophic | An elevated scar, resembling a keloid, but which does not spread into surrounding tissues. It is formed by enlargement and overgrowth of cicatricial tissue and regresses spontaneously. (12 Dec 1998) |
|---|---|
| progressive hypertrophic polyneuropathy | A familial type of demyelinating sensorimotor polyneuropathy that begins in early childhood and is slowly progressive; clinically characterised by foot pain and paresthesias, followed by symmetrical weakness and wasting of the distal limbs; one of the causes of stork legs; patients are wheelchair bound at an early age; peripheral nerves are palpably enlarged and non-tender; pathologically, onion bulb formation is seen in the nerves: whorls of overlapping, intertwined Schwann cell processes that encircle bare axons; usually autosomal recessive inheritance. Synonym: Dejerine's disease, progressive hypertrophic polyneuropathy. (05 Mar 2000) |
| hereditary hypertrophic neuropathy | dejerine-Sottas disease |
| hypertrophic | Relating to or characterised by hypertrophy. (05 Mar 2000) |
| hypertrophic arthritis | <pathology> Noninflammatory degenerative joint disease occurring chiefly in older persons, characterised by degeneration of the articular cartilage, hypertrophy of bone at the margins and changes in the synovial membrane. It is accompanied by pain and stiffness, particularly after prolonged activity. Origin: Gr. Arthron = joint (18 Nov 1997) |
| hypertrophic cardiomyopathy | <cardiology, pathology> A congenital heart disease that results in abnormal thickening of the ventricular septum and left ventricular wall. Enlargement of the ventricular septum can result in ventricular outflow obstruction (subaortic stenosis) and eventual cardiomyopathy. Origin: Gr. Pathos = disease (27 Sep 1997) |
| hypertrophic cervical pachymeningitis | A fibrotic and inflammatory thickening of spinal pachymeninges, particularly in the cervical region, resulting in spinal nerve radiculopathy; believed to be of syphilitic aetiology. (05 Mar 2000) |
| hypertrophic dystrophy | Increase in the number of cells in a squamous epithelium. Synonym: hypertrophic dystrophy. (05 Mar 2000) |
| hypertrophic gastritis | Gastric mucosal hyperplasia, either mucoid or glandular; the latter type may be associated with the Zollinger-Ellison syndrome. Synonym: giant hypertrophy of gastric mucosa, hypertrophic gastritis, Menetrier's syndrome. (05 Mar 2000) |
| 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 pyloric stenosis | <radiology> Not seen until 3 weeks, projectile vomiting, palpable olive in RUQ/epigastrium (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) |
