| Duret's lesion | Small haemorrhage(s) in the floor of the fourth ventricle or beneath the aqueduct of Sylvius. (05 Mar 2000) |
|---|---|
| Janeway lesion | One of the stigmata of infectious endocarditis: irregular, erythematous, flat, painless macules on the palms, soles, thenar and hypothenar eminences of the hands, tips of the fingers, and plantar surfaces of the toes; rarely a diffuse rash. In acute endocarditis the lesions may be haemorrhagic or purple. (05 Mar 2000) |
| upper motor neuron lesion | Injury to cerebral descending (corticonuclear) fibres above the brainstem or spinal motor nerve nucleus. Synonym: upper motor neuron lesion. (05 Mar 2000) |
| Lennert's lesion | <tumour> Malignant lymphoma with a high proportion of diffusely scattered epithelioid cells, tonsillar involvement, and an unpredictable course. Synonym: Lennert's lesion. (05 Mar 2000) |
| lesion | <pathology> Any pathological or traumatic discontinuity of tissue or loss of function of a part. Origin: L. Laesio, laedere = to hurt (18 Nov 1997) |
| Lohlein-Baehr lesion | Focal embolic glomerulonephritis occurring in bacterial endocarditis. Synonym: Baehr-Lohlein lesion. (05 Mar 2000) |
| lower motor neuron lesion | Injury to motor cells in the brainstem or spinal cord, or of the axons derived from them. (05 Mar 2000) |
| adenoid cystic carcinoma | <tumour> A histologic type of carcinoma characterised by large epithelial masses containing round, glandlike spaces or cysts which frequently contain mucus or collagen and are bordered by a few or many layers of epithelial cells without intervening stroma, forming a cribriform pattern like a slice of Swiss cheese; perineural invasion and haematogenous metastasis are common; occurs most commonly in salivary glands. Synonym: cylindromatous carcinoma. (05 Mar 2000) |
| carcinoma, adenoid cystic | Carcinoma characterised by bands or cylinders of hyalinised or mucinous stroma separating or surrounded by nests or cords of small epithelial cells. When the cylinders occur within masses of epithelial cells, they give the tissue a perforated, sievelike, or cribriform appearance. Such tumours occur in the mammary glands, the mucous glands of the upper and lower respiratory tract, and the salivary glands. They are malignant but slow-growing, and tend to spread locally via the nerves. (12 Dec 1998) |
| pancreatic cystic neoplasms | <radiology> Microcystic adenoma, glycogen, benign, mucinous cystic neoplasm, macrocystic adenoma, cystadenoma/cystadenocarcinoma, mucin, pre-malignant, Both occur more commonly in women, peak in middle age (12 Dec 1998) |
| papillary cystic adenoma | <tumour> An adenoma in which the lumens of the acini are frequently distended by fluid, and the neoplastic epithelial elements tend to form irregular, fingerlike projections. (05 Mar 2000) |
| medullary cystic disease | <disease> A rare hereditary kidney disease characterised by the gradual loss of kidney function due to the presence of cysts in the renal medulla. Symptoms include high urine output (cannot concentrate the urine), weakness, weight loss, nocturia, fatigue and headache. There is no cure and usually progresses from chronic renal failure to end stage renal disease. (27 Sep 1997) |
| medullary cystic kidney disease | <radiology> Mode of inheritance uncertain, usually affects young adults (early 20s), associated with red or blond hair (!!), causes salt wasting, polyuria, azotaemia, affects both kidneys, with progressive disease patients need dialysis or transplant (12 Dec 1998) |
| mesothelioma, cystic | A peritoneal mesothelioma affecting mainly young females and producing cysts of variable size and number lined by a single layer of benign mesothelial cells. The disease follows a benign course and is compatible with a normal life expectancy, requiring occasionally partial excision or decompression for relief of pain or other symptoms. Malignant potential is exceptional. (12 Dec 1998) |
| chronic cystic mastitis | Older term corresponding to fibrocystic condition of the breast. (05 Mar 2000) |
