To better understand the exact location and pattern of TSLP expression in the skin of patients suffering from different dermatoses, we analyzed by immunohistochemistry retrospective samples of representative immune-related dermatoses, including LP, discoid lupus erythematosus (DLE), PsV, BP, eczema, sarcoidosis, and mycosis fungoides (MF). This evidence concerns the gene TSLP and discoid lupus erythematosus.
