| cutaneous T-cell lymphoma | <oncology, tumour> A type of non-Hodgkin's lymphoma that first appears on the skin. Synonym: mycosis fungoides. (13 Nov 1997) |
| histiocytic lymphoma | <tumour> A malignant tumour of reticular tissue composed predominantly of neoplastic histiocytes. See: large cell lymphoma. (05 Mar 2000) |
| Hodgkin's lymphoma | <haematology, oncology> A human malgnant disorder of lymph tissue (lymphoma) that appears to originate in a particular lymph node and later spreads to the spleen, liver and bone marrow. It occurs mostly in individuals between the ages of 15 and 35. It is characterised by progressive, painless enlargement of the lymph nodes, spleen and general lymph tissue. Giant cells, the Reed Sternberg cells, with mirror image nuclei are diagnostic. Immunological depletion, caused perhaps by the excessive growth of neoplastic histiocytes, occurs. Four types of the disease are recognised depending on the relative predominance of various neoplastic derivatives of the lymphoid series. Pyrexia is often a feature of the disease. Death often results from generalised immunological inability to respond to infections. If detected early, it has a high remission rate. Staging: Ann Arbor classification; each stage is further classified as:, A no symptoms, B fever, sweats, weight loss. Stage I - involvement of a single lymph-node region or extralymphatic site. Stage II - two or more sites of involvement on the same side of the diaphragm. Stage III - disease involvement on both sides of the diaphragm. Stage IV - disseminated disease of extralymphatic organs, with or without lymph-node involvement. Indicence: approximately 1,500 new cases per year in the UK. (30 Mar 2000) |
| human T-cell lymphoma/leukaemia virus | A group of viruses (subfamily Oncovirinae, family Retroviridae) that are lymphotropic with a selective affinity for the helper/inducer cell subset of T lymphocytes and that are associated with adult T-cell leukaemia and lymphoma. Synonym: human T-cell lymphotropic virus. (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) |
| nodular lymphoma | <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) |
| non-Hodgkin's lymphoma | <oncology, tumour> A group of lymphomas which differ in important ways from Hodgkin's disease and are classified according to the microscopic appearance of the cancer cells. The disease is classified as either low grade (slowly growing), intermediate grade or high grade (rapidly growing) and may be treated in a variety of ways depending on the exact diagnosis. Previously called lymphosarcoma. (30 Sep 1997) |
| immunoblastic lymphoma | <tumour> A monomorphous proliferation of immunoblasts involving the lymph nodes; it may develop in some patients with angioimmunoblastic lymphadenopathy. (05 Mar 2000) |
| T-cell lymphoma | A cancer of the immune system that appears in the skin; also called mycosis fungoides. (12 Dec 1998) |
| T-cell-rich, B-cell lymphoma | <tumour> A B-cell lymphoma in which more than 90% of the cells are of T-cell origin, masking the large cells that form the neoplastic B-cell component. See: adult T-cell lymphoma. (05 Mar 2000) |
| extra nodal lymphoma | <oncology, tumour> Literally outside the lymph nodes, but exhibiting the characteristics of lymph node cancer. A term used to describe the extent and site of disease. (27 Sep 1997) |
| Ki-1+ lymphoma | <tumour> A form of lymphoma characterised by anaplasia of cells, sinusoidal growth, and immunoreactivity with CD30 (Ki-1 or Ber-H2). Synonym: Ki-1+ lymphoma. (05 Mar 2000) |
| large cell lymphoma | <oncology, tumour> Highly malignant group of tumours arising from transformed lymphocytes or myeloid precursors. Cell of origin often obscure. (18 Nov 1997) |
| Lennert's lymphoma | <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) |
