• Tests of specific aspects of immune function were conducted on 15 patients with clinically and histologically evident mycosis fungoides of various stages. These tests included peripheral blood lymphocyte counts, T and B cell counts, mitogen stimulation tests to phytohemagglutinin (PHA), concanavalin A (con A), and pokeweed mitogen, as well as determinations of IgE levels and antinuclear factor (ANF). We found that mycosis fungoides patients, as a group, had normal peripheral blood lymphocyte, T cell, and B cell counts, but had decreased stimulation to PHA and con A. When evaluated by stage of disease, the peripheral blood lymphocytes, T and B cell counts did not differ significantly from normal, at least until stage V. Concanavalin A stimulation was decreased by stage II disease, and PHA was decreased by stage III, indicating at least a selective immunological deficit in the plaque stage or in later disease. Values of IgE and ANF were rarely abnormal.
