The techniques of flow cytofluorometry and immune cytochemistry combined with routine cytological analysis were applied to 81 patients with non-Hodgkin's lymphomas to diagnose the malignant lymphomas and to determine their immune phenotypes. The accuracy of proposed techniques combination to diagnose the malignant lymphoma consists 98% and to determine the immune phenotype - 90%. The presented combination of routine cytological analysis combined with techniques of flow cytofluorometry and immune cytochemistry is the express-technique to diagnose lymphoma and its immune phenotype the day of patient visit to the doctor. This approach significantly increases the role of cytological method in diagnostics of lymphomas. The technique makes it possible to analyze simultaneously huge quantity number of lymph nodes, including deep-seated and not only the superficial lymph nodes.
