Figure 2. Immunophenotype of lymphocytes in a skin lesion of suspected early MF. The skin lesion from a patient with suspected early MF was stained with respective antibodies by the SP, Elivision, or EnVision method. The lymphocytes infiltrated in the epidermis express T-cell-associated antigens CD2, CD3eϵ, CD7, and CD45RO (SP method). Lymphocytes express βF1 (Elivision) and CD4 (EnVision) derived from αβ cells with a helper T cell profile.
