PG - 1030-7 AB - Skin biopsies from 136 patients with 30 different dermatoses and eight biopsies of normal skin were investigated with the avidin-biotin-peroxidase complex method with regard to the expression of major histocompatibility complex class II antigens human leukocyte antigen (HLA) HLA-DR, HLA-DQ, HLA-DP on keratinocytes. In normal skin the expression of these antigens was restricted to acrosyringia and Langerhans cells. In the dermatoses investigated HLA-DR was found in 51.5% (70 of 136), HLA-DQ in 24.3% (33 of 136), and HLA-DP in 20.5% (8 of 39). In 37 cases (27.2%) only HLA-DR could be detected, whereas in 33 cases (24.3%) HLA-DR was expressed jointly with HLA-DQ. Coexpression of HLA-DR and HLA-DQ was found especially often in cutaneous T cell lymphomas, skin tumors, and inflammatory dermatoses.
