| denture hyperplasia | Overgrowth of tissue in the mucobuccal or labial fold, induced by chronic trauma from ill-fitting dentures. Synonym: denture hyperplasia, epulis fissuratum. (05 Mar 2000) |
|---|---|
| ductal hyperplasia | Hyperplasia characterised by intraductal proliferation of epithelial cells, e.g., in the breast. (05 Mar 2000) |
| idiopathic fibrous hyperplasia | A condition of cystic bone growth that results from abnormal bone development. May occur with bone lesions, skin pigmentation and endocrine abnormalities. See: McCune-Albright syndrome. Origin: Gr. Plassein = to form (27 Sep 1997) |
| inflammatory fibrous hyperplasia | Overgrowth of tissue in the mucobuccal or labial fold, induced by chronic trauma from ill-fitting dentures. Synonym: denture hyperplasia, epulis fissuratum. (05 Mar 2000) |
| 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) |
| thymus hyperplasia | Enlargement of the thymus. A condition described in the late 1940's and 1950's as pathological thymic hypertrophy was status thymolymphaticus and was treated with radiotherapy. Unnecessary removal of the thymus was also practiced. It later became apparent that the thymus undergoes normal physiological hypertrophy, reaching a maximum at puberty and involuting thereafter. The concept of status thymolymphaticus has been abandoned. Thymus hyperplasia is present in two thirds of all patients with myasthenia gravis. (12 Dec 1998) |
| endometrial hyperplasia | <gynaecology, pathology> Thickening of the endometrial lining due to an overgrowth of mucosal cells. Symptoms often include irregular vaginal bleeding, heavy or prolonged menstrual cycles and post-menopausal bleeding in older women. Origin: Gr. Plassein = to form (07 Apr 1998) |
| transmissible murine colonic hyperplasia | A disease of young mice caused by the bacterium Citrobacter freundii and characterised by diarrhoea and mucosal hyperplasia of the descending colon. (05 Mar 2000) |
| fibromuscular hyperplasia | Thickening of arterial media by fibrosis and muscular hyperplasia, usually involving the renal arteries and causing multifocal stenosis and hypertension; a variety of fibromuscular dysplasia. (05 Mar 2000) |
| focal epithelial hyperplasia | Hyperplasia of the mucous membrane of the lips, tongue, and less commonly, the buccal mucosa, floor of the mouth, and palate, presenting soft, painless, round to oval sessile papules about 1 to 4 mm in diameter. The condition usually occurs in children and young adults and has familial predilection, lasting for several months, sometimes years, before running its course. A viral aetiology is suspected, the isolated organism being usually the human papilloma virus. (12 Dec 1998) |
| focal nodular hyperplasia | <radiology> Focal nodules of normal hepatocytes, Kuppfer cells and bile ducts, F more than M, rare, benign, multiple in 20%, haemorrhage (most common complication) in only 2-3% (unlike hepatic adenoma), stellate fibrous septae (stellate scar), NM: normal or increased uptake on HIDA and sulfur colloid (12 Dec 1998) |
| anterior tibial node | A small inconstant lymph node in front of the interosseous membrane along the upper part of the anterior tibial vessels. Synonym: nodus tibialis anterior, anterior tibial node. (05 Mar 2000) |
| artery to atrioventricular node | The atrioventricular branches or the nodal branches, the small arteries supplying the atrioventricular node; they usually arise from the right coronary artery where it starts to descend the posterior interventricular sulcus. Synonym: ramus nodi atrioventricularis, atrioventricular nodal branch, branch to atrioventricular node. (05 Mar 2000) |
| artery to the sinuatrial node | Ascending atrial branch, usually (55%) arising from the anterior stem of the right coronary artery (but 35-45% arising from the circumflex branch of the left coronary artery), which runs around the base of the superior vena cava to reach the sinuatrial node. Synonym: ramus nodi sinuatrialis arteriae coronaria dextra, branch to sinuatrial node, sinuatrial nodal branch of right coronary artery, sinuatrial node artery. (05 Mar 2000) |
