| nodular non-X histiocytosis | A rare recurring generalised eruption in adults of flesh coloured or erythematous papules remaining localised to the skin and consisting of dermal nodules of mononuclear histiocytes that do not stain for lipid. Synonym: nodular non-X histiocytosis. (05 Mar 2000) |
| nodular opacity | A solitary, round, circumscribed shadow found in the lung on chest radiograph; causes include granuloma, primary or metastatic carcinoma, benign tumour, vascular malformation. Synonym: coin lesion of lungs. (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) |
| nodular scleritis | Firm, immobile, single or multiple areas of localised scleritis. (05 Mar 2000) |
| nodular sclerosis | <cardiology, pathology> The progressive narrowing and hardening of the arteries over time. This is known to occur to some degree with aging, but other risk factors that accelerate this process have been identified. These factors include: high cholesterol, high blood pressure, smoking, diabetes and family history for atherosclerotic disease. (27 Sep 1997) |
| nodular subepidermal fibrosis | A slowly growing benign skin nodule consisting of poorly demarcated cellular fibrous tissue enclosing collapsed capillaries with scattered haemosiderin-pigmented and lipid macrophages. They are common, usually about 1 cm in diameter and occur in the dermis. Simple excision is always curative. (12 Dec 1998) |
| nodular syphilid | Origin: NL. So called from its gummy contents See Gum. <medicine> A kind of soft tumour, usually of syphilitic origin. Source: Websters Dictionary (01 Mar 1998) |
| nodular transformation of the liver | 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) |
| nodular tuberculid | A type of panniculitis characterised histologically by the presence of granulomas, vasculitis, and necrosis. It is traditionally considered to be the tuberculous counterpart of nodular vasculitis, but is now known to occur without tuberculous precedent. It is seen most commonly in adolescent and menopausal women, is initiated or exacerbated by cold weather, and typically presents as one or more recurrent erythrocyanotic nodules or plaques on the calves. The nodules may progress to form indurations, ulcerations, and scars. (12 Dec 1998) |
| nodular vasculitis | Chronic or recurrent nodular lesions of subcutaneous tissue, especially of the legs of older women, with lobular panniculitis, granulomatous inflammation with multinucleated giant cells, focal necrosis, and obliterative inflammation of the small blood vessels, resembling erythema induratum but without evidence of associated tuberculosis. (05 Mar 2000) |
| interstitial pattern | One of several chest radiographic patterns associated with interstitial infiltration or thickening, including honeycomb pattern, miliary pattern, reticulonodular pattern, or septal lines. (05 Mar 2000) |
| occlusal pattern | The form of the occlusal surface of a tooth or a row of teeth. Synonym: occlusal pattern. (05 Mar 2000) |
| three-dimensional diffraction pattern | <optics> The diffraction pattern (of a point source) that appears in the three-dimensional space in and near the focal plane. For an aberration-free, diffraction- limited system, the slice of the diffraction pattern in the focal plane is the Airy disk and its surrounding diffraction rings. Above and below focus, the pattern changes periodically along the axis of the light beam so that bright and dark Airy-disk-like patterns appear alternately. The axial period of repeat is spaced twice as far apart as the radial period of repeat in the Airy disk and its diffraction rings (05 Aug 1998) |
| Electron Channeling Pattern | <microscopy> A pattern formed by the periodic backscattering of electrons by the specimen lattice in a transmission electron microscope. Allows determination of crystal structure and lattice parameters in crystals greater than 10 micrometres diameter. Acronym: ECP (05 Aug 1998) |
