| 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) |

| adenocarcinoma, follicular | An adenocarcinoma of the thyroid gland, in which the cells are arranged in the form of follicles. (12 Dec 1998) |
| carcinoma, papillary, follicular | A thyroid neoplasm of mixed papillary and follicular arrangement. Its biological behaviour and prognosis is the same as that of a papillary adenocarcinoma of the thyroid. (12 Dec 1998) |
| giant follicular lymphoblastoma | <tumour> A malignant lymphoma arising from lymphoid follicular B-cells which may be small or large, growing in a nodular pattern. Synonym: follicular lymphoma, giant follicular lymphoblastoma. (05 Mar 2000) |

| chronic follicular conjunctivitis | Indolent inflammation of the conjunctiva, with discrete follicles in fornices that may be infective, toxic, or irritant in nature. (05 Mar 2000) |
| mucinosis, follicular | A disease of the pilosebaceous unit, presenting clinically as grouped follicular papules or plaques with associated hair loss. It is caused by mucinous infiltration of tissues, and usually involving the scalp, face, and neck. It may be primary (idiopathic) or secondary to mycosis fungoides or reticulosis. (12 Dec 1998) |
| inverted follicular keratosis | A solitary benign epithelial tumour of infundibular hair follicle origin occurring on the face, consisting of a lobulated epidermal downgrowth of keratinizing squamous cells with a pattern of eddies or whorls. (05 Mar 2000) |
