Figure 2: Stable vitiligo. (a) Decreased melanin pigment in basal cell layer (H and E, ×400). (b) Mild lymphocytic cell infiltrate in the papillary dermis (H and E, ×400) Inset shows absence of melanin in the lesional area flanked by perilesional areas showing melanin preservation (MF, ×200). (c) Occasional presence of human melanoma black-45 positive melanocytes (arrow) in the basal layer (IHC, ×400). Inset shows normal melanin pigmentation in the positive control section on human melanoma black-45 immunostaining (IHC, ×400). (d) Epidermis showing occasional S-100 positive Langerhans cells (arrows) on immunostaining (IHC, ×400)
