Figure 2. Immunohistochemical phenotyping of cellular infiltrates at the dermal-epidermal border.

Figure 2

Serial sections at the dermal-epidermal border, demonstrate that APCs are the dominant cell type adjacent to the central necrotic zone of the eschar. Immunophenotyping by MHC class II receptor for APCs (Panel A: HLADR), macrophages (B: CD68) and DCs (C: DC-SIGN, D: FXIIIa, G: S100 and H: LSECtin), neutrophils (E: CD15) and lymphocytes (F: CD4). The proportion of dendritic cells was higher in the dermal-epidermal border zone, than in the deeper dermis. Subepidermal vacuolization is prominent. Patient TM2663, magnification ×400, counterstained with haematoxylin, peroxidase immunostaining in brown.
