| gingival hyperplasia | Non-inflammatory enlargement of the gingivae produced by factors other than local irritation. It is characteristically due to an increase in the number of cells. (12 Dec 1998) |
|---|---|
| cementum hyperplasia | A regressive change of teeth characterised by excessive development of secondary cementum on the tooth surface. It may occur on any part of the root, but the apical two-thirds are most commonly affected. (12 Dec 1998) |
| congenital sebaceous hyperplasia | Misnomer for nevus sebaceus. (05 Mar 2000) |
| cystic hyperplasia | Formation of multiple retention cysts from obstruction of ducts or glands by hyperplasia of the lining epithelium, as in fibrocystic disease of the breast and metropathia haemorrhagica. (05 Mar 2000) |
| cystic hyperplasia of the breast | A benign disease common in women of the third, fourth, and fifth decades characterised by formation, in one or both breasts, of small cysts containing fluid which may appear as blue dome cysts; associated with stromal fibrosis and with variable degrees of intraductal epithelial hyperplasia and sclerosing adenosis. Synonym: cystic hyperplasia of the breast. (05 Mar 2000) |
| prostatic hyperplasia | Enlargement or overgrowth of the prostate gland as a result of an increase in the number of its constituent cells. (12 Dec 1998) |
| pseudoepitheliomatous hyperplasia | Pseudocarcinomatous hyperplasia, a benign marked increase and downgrowth of epidermal cells, observed in chronic inflammatory dermatoses; microscopically, it resembles well-differentiated squamous cell carcinoma. (05 Mar 2000) |
| senile sebaceous hyperplasia | Hyperplasia of mature sebaceous glands, forming a nodule on the skin of the face or forehead in elderly persons. (05 Mar 2000) |
| hyperplasia | <pathology> The abnormal multiplication or increase in the number of normal cells in normal arrangement in a tissue. Compare: hypertrophy. Origin: Gr. Plasis = formation (18 Nov 1997) |
| squamous cell hyperplasia | Increase in the number of cells in a squamous epithelium. Synonym: hypertrophic dystrophy. (05 Mar 2000) |
| neuronal hyperplasia | Increased numbers of ganglion cells with myenteric plexus hyperplasia and increased acetylcholinesterase activity in nerves of the mucosa and submucosa. Clinically, neuronal hyperplasia mimics Hirschprung's disease. Similar findings are seen in patients with multiple endocrine neoplasia syndrome, type IIB, and in neurofibromatosis. Synonym: hyperganglionosis, neuronal intestinal dysplasia. (05 Mar 2000) |
| 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) |
