| light chain-related amyloidosis | A form of primary amyloidosis in which the fibrillar amyloid deposits are derived from the amino terminal variable region of the light chains of immunoglobulin; seen in B-lymphocyte and plasma-cells dyscrasias. (05 Mar 2000) |
| calcific nodular aortic stenosis | Most common type of aortic stenosis, occurring usually in elderly men, in which the cusps contain calcified fibrous nodules on both surfaces; the causes include rheumatic fever, atherosclerosis, age-related degeneration, and congenitally bicuspid aortic valve. (05 Mar 2000) |
| panniculitis, nodular nonsuppurative | A form of panniculitis characterised by recurrent episodes of fever accompanied by the eruption of single or multiple erythematous subcutaneous nodules on the lower extremities. They normally resolve, but tend to leave depressions in the skin. The condition is most often seen in women, alone or in association with other disorders. (12 Dec 1998) |
| goiter, nodular | An enlarged thyroid gland containing circumscribed nodules within its substance. (12 Dec 1998) |
| Salzmann's nodular corneal degeneration | Large and prominent nodules of a solid, opaque material that stands out from the surface of the cornea; occurs occasionally in persons previously affected by phlyctenular keratitis. (05 Mar 2000) |
| nodular | Bumpy. (12 Dec 1998) |
| nodular arteriosclerosis | Atheromas occurring in the arterial intima as discrete tumours. (05 Mar 2000) |
| nodular body | In fungi, a compact, roughly spherical or squarish structure formed by coiling and twisting of the end of a hypha; considered to be abortive growths toward sexual reproduction. (05 Mar 2000) |
| nodular disease | Oesophagostomiasis in herbivores and primates, characterised by nodules in the wall of the large intestine, caecum, and occasionally, the ileum; the nodules are filled with caseous material and result from host response to encystment of the larvae of Oesophagostomum species. (05 Mar 2000) |
| nodular episcleritis | Episcleritis with localised inflammation foci in episcleral tissues. (05 Mar 2000) |
| nodular fasciitis | A rapidly-growing tumour-like proliferation of fibroblasts, not thought to be neoplastic, with mild inflammatory exudation occurring in fascia; the fibrosis may infiltrate surrounding tissue but does not progress indefinitely or metastasize. Synonym: pseudosarcomatous fasciitis. (05 Mar 2000) |
| nodular headache | Radiating pain in the head accompanied by nodular swellings in the splenius, frontalis, trapezius, and other muscles. (05 Mar 2000) |
| nodular hidradenoma | <tumour> A tumour derived from eccrine sweat glands, composed of glycogen-rich clear cells. Synonym: eccrine acrospiroma, nodular hidradenoma. (05 Mar 2000) |
| nodular histiocytic lymphoma | <tumour> A B-cell lymphoma with nodular or diffuse lymph node or bone marrow involvement by large lymphoid cells. Synonym: follicular predominantly small cleaved cell lymphoma, nodular histiocytic lymphoma. (05 Mar 2000) |
