Vessels of the superficial dermis were dilated and telangiectatic, with thickened vascular walls (Figure 2), and were surrounded by a thick lamellar band of hyalinized eosinophil material seen on periodic acid –Schiff staining (Figure 3). Dermal inflammatory infiltrate and vasculitis were absent. Congo red staining revealed no deposits (not shown). Toluidine blue staining revealed a normal number of dermal mast cells. Direct immunofluorescence testing of a frozen skin specimen for IgG, IgM, IgA, and C3 gave negative results. This association of clinical and histological aspects was consistent with the diagnosis of CCV. No treatment was proposed.
