Abstract
Peripheral blood lymphocytes from 16 mycosis fungoides (MF) patients were studied using OKT series monoclonal antihuman T cell antibodies. The percentage of OKT3+ cells was in normal range for all MF patients compared with controls; the percentage of OKT4+ cells was significantly increased (p < 0.002) in MF patients versus controls; the percentage of OKT8+ and OKT11+ cells in the MF group did not differ from controls. The OKT4+ cell expansion was apparently not dependent from the clinical stage of disease. These findings suggest that in MF patients there is a circulating OKT4+ cell expansion and, indirectly, that MF could be regarded as a helper T cell neoplasm.
