Figure 2: (a) Histological examination of the biopsy showed pigmentation of the basal layer of the epidermis and dense mononuclear cell infiltration in the papillary dermis (hematoxylin-eosin staining, original magnification × 200). (b) Toluidine blue staining revealed many mast cells within the infiltrating cells (original magnification × 200). (c) Dylon staining revealed an increased number of eosinophils (original magnification × 200). (d) Immunohistochemistry results revealed interleukin 5-positive cells within the upper dermis (original magnification × 400)
