It can happen.: In individuals with lupus and skin involvement, the pattern of inflammation seen microscopically is an interface pattern. Inflammatory cells in this pattern involve the junction of the epidermis and dermis. Melanocytes are located in this area, and the pigmentation of epidermal cells is disrupted. In some individuals, this results in hyperpigmentation; in others, there can be hypopigmentation.
