| 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) |
| follicular 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) |
| follicular predominantly large cell lymphoma | <tumour> A B-cell lymphoma of intermediate malignancy. (05 Mar 2000) |
| follicular predominantly small cleaved cell 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) |
| 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) |
| lymphoblastic lymphoma | <tumour> A diffuse lymphoma in children, with supradiaphragmatic distribution and T lymphocytes having convoluted nuclei; many patients develop acute lymphoblastic leukaemia. (05 Mar 2000) |
| lymphocytic lymphoma | <oncology, tumour> A cancer of lymphatic tissues, the tumour cells are mostly abnormal lymphocytes. (13 Nov 1997) |
| lymphoma | <oncology, tumour> Malignant tumour of lymphoblasts derived from B lymphocytes. most commonly affects children in tropical Africa: both Epstein Barr virus and immunosuppression due to malarial infection are involved. (18 Nov 1997) |
| lymphoma, aids-related | B-cell lymphoid tumours that occur in association with aids. Patients often present with an advanced stage of disease and highly malignant subtypes including burkitt lymphoma, immunoblastic large-cell lymphoma, small non-cleaved-cell lymphoma and diffuse large-cell lymphoma. The tumours are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in aids is a complex result of ebv infection, HIV antigenic stimulation, and T-cell-dependent HIV activation. (12 Dec 1998) |
| lymphoma, B-cell | A group of heterogeneous lymphoid tumours generally expressing one or more B-cell antigens or representing malignant transformations of B-lymphocytes. (12 Dec 1998) |
| lymphoma, diffuse | Malignant lymphoma in which neoplastic cells diffusely infiltrate the entire lymph node without any definite organised pattern. Patients whose lymphomas present a diffuse pattern generally have a more unfavorable survival outlook than those presenting with a follicular or nodular pattern. (12 Dec 1998) |
