In contrast, TSLP was detected in the epidermis in 3 of 13 in situ melanoma (23%) (2 TSLP– and 2 TSLP+ biopsies are shown in Figure 7D) and in 48 of 57 invasive melanoma (85%) (6 biopsies are shown in Figure 7E) at varying levels, but all were located in epidermal suprabasal layers, similar to what was previously reported in atopic dermatitis lesioned skin (40). This evidence concerns the gene TSLP and atopic eczema.
