[Histopathology of malignant lymphomas].
Histopathological features of malignant lymphomas were described and discussed. For the standard classification of malignant lymphomas, the Rye classification for Hodgkin's disease and the International Working Formulation for the non-Hodgkin's lymphoma were recommended. Recent advances in immunology make immunophenotyping of lymphoma cells possible. The usefulness of immunophenotyping in routine paraffin sections was suggested. Some problems of the Working Formulation in classifying T-cell lymphomas were also discussed. A significant difference in the 5-year survival between the different histological grades of Working Formulation and between T and B phenotypes was found in a survey using 604 non-Hodgkin's lymphoma cases of our own. It is concluded that precise histological typing and immunophenotyping of lymphomas are mandatory in the diagnosis, treatment and prediction of the prognosis of patients with malignant lymphomas.
