PLEVA-like histopathologic features such as hyperkeratosis in the epidermis, mild acanthosis, elongated rete ridges, vacuolization of the basal layer with exocytosis of inflammatory cells, lymphohistiocytic infiltration around the vascular plexus and red blood cells (RBC) extravasation in the dermis were noticed in the H&E staining figures.
