lymphoma
Pronunciation (lim-fō′mă)
- Any neoplasm of lymphoid or reticuloendothelial tissues; in general use, synonymous with malignant lymphoma; present as apparently solid tumors composed of cells that appear primitive or resemble lymphocytes, plasma cells, or histiocytes. Lymphomas appear most frequently in the lymph nodes, spleen, or other normal sites of lymphoreticular cells; may invade other organs or manifest as leukemia. Lymphomas are now classified by histology, immunophenotype, and cytogenetic analysis, according to cell of orgin (B or T cells) and degree of maturation. The current World Health Organization (WHO) classification of lymphoid neoplasms is based on the Revised European-American Lymphoma (REAL) classification and effectively replaces older schemes such as the Working Formulation and Rappaport classification, which were based solely on morphology.

[lympho- + G. -oma, tumor]
