Methods
Dermoscopy of few lesions showed central crustings, reddish areas with
dotted and linear vessels surrounded by peripheral white scales (figure
2a) while the majority of lesions had a target pattern of central crust,
intermediate vascular ring surrounded by white scales on pinkish
background (figure 2b).Some lesions also revealed central necrotic areas
around the hair follicles with peripheral crustings and scalings (figure
2c).
Histopathological examination of the lesion from left forearm
demonstrated focal parakeratosis,spongiosis,vacuolar degeneration in
basal layer with lymphocytic and neutrophilic infiltrations,epidermal
exocytosis and extravasation of RBCs (figure 1b, 1c).
