Compared to that in HC, TSLP was significantly expressed semiquantitatively in the stratum basale of the epidermis with PsV (p = 0.002) and sarcoidosis (p =0.025) specimens and not significantly expressed in LP (p = 0.102), DLE (p = 0.360), eczema (p = 0.253), BP (p = 0.145), and MF (p = 0.436) (Figure 2(a)). Here, TSLP is linked to sarcoidosis.
