Cells with morphologically distinctive nuclei, heretofore associated only with mycosis fungoides and the Sézary syndrome, are readily detected in a variety of randomly selected nonlymphomatous dermatoses. These cells, therefore, do not provide specific cytologic evidence for the diagnosis of mycosis fungoides. The significance and function of these cells need further clarification.
