| TLLT-cell | leukemia or lymphoma |
| 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) |
| lymphoma, follicular | Malignant lymphoma in which the lymphomatous cells are clustered into identifiable nodules within the lymph nodes. The nodules resemble to some extent the germinal centres of lymph node follicles and most likely represent neoplastic proliferation of lymph node-derived follicular centre B-lymphocytes. This class of lymphoma usually occurs in older persons, is commonly multinodal, and possibly extranodal. Patients whose lymphomas present a follicular or nodular pattern generally have a more indolent course than those presenting with a diffuse pattern. (12 Dec 1998) |
| lymphoma, high-grade | One of the three major prognostic groupings for non-hodgkin lymphomas as proposed in the working formulation of the non-hodgkin's lymphoma pathologic classification project sponsored by the national cancer institute (1981). Lymphomas falling within this group have a relatively unfavorable survival potential. (12 Dec 1998) |
| lymphoma, intermediate-grade | One of the three major prognostic groupings for non-hodgkin lymphomas as proposed in the working formulation of the non-hodgkin's lymphoma pathologic classification project sponsored by the national cancer institute (1981). Lymphomas falling within this group have an intermediate survival potential. (12 Dec 1998) |
| lymphoma, large-cell | A form of malignant lymphoma in which the malignant cells resemble histiocytes morphologically but are presently considered to be derived from lymphoid elements. These cells are irregular in shape with relatively abundant, frequently acidophilic cytoplasm. Large-cell lymphoma can occur in both nodular (follicular) and diffuse forms, with the latter being more frequently seen. (12 Dec 1998) |
| lymphoma, large-cell, diffuse | Malignant lymphoma composed of large cells which may be both cleaved and noncleaved. The pattern is predominantly diffuse. most of these lymphomas represent the malignant counterpart of B-lymphocytes at midstage in the process of differentiation. (12 Dec 1998) |
| lymphoma, large-cell, follicular | Malignant lymphoma in which the majority of neoplastic cells within the follicles are large cleaved or noncleaved cells. The degree to which the follicular centre cells retain their ability to form follicles varies with the state of B-cell transformation. (12 Dec 1998) |
