| Fibrocytes with thin nuclei and long tails of cytoplasm, sometimes stellate, in the upper part of the dermis |
| Prominent telangiectases in the upper part of the dermis |
| Siderophages and melanophages in the upper part of the dermis |
| Epidermal and adnexal basement membranes thickened markedly |
| Vacuolar alteration along the dermoepidermal junction |
| Smudged appearance of the dermoepidermal junction |
| Epidermis thinned focally; basal keratinocytes sometimes displaying pleomorphic nuclei and some possibly necrotic |
