a) Representative histological picture showing perivascular inflammatory infiltrate in papillary and mid dermis associated to erythrocyte extravasation and mild dermal oedema. The epidermis showed only focal spongiosis and basal vacuolization (Hematoxylin-Eosin, Original magnification 100x). b) At higher magnification, the inflammatory cells were predominantly composed by small lymphocytes, hystiocites nd eosinophils around and within capillary vessels (Hematoxylin-Eosin, Original magnification 200x)
