| 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) |
| nodular hyperplasia of prostate | Glandular and stromal hyperplasia occurring very commonly in the middle and lateral lobes of older men, forming nodules that may increasingly obstruct the urethra. Synonym: benign prostatic hypertrophy. (05 Mar 2000) |
| nodular regenerative hyperplasia | A rare condition in which nodules of hyperplastic hepatocytes develop without fibrosis or general loss of lobular architecture. Synonym: nodular regenerative hyperplasia. (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) |
| 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) |
