Ecchymotic macule on a pigmented lesion following trauma.

Physical examination revealed a pigmented macule in the left scapular region; its purplish red coloration gave the lesion a bruise-like appearance and ecchymotic spots were visible in the central area (Fig. 1A) The most characteristic dermoscopic findings were areas characterized by a lightish brown fine reticular pattern around the periphery and a pseudo-lacunar background pattern dotted with thrombosed vessels in the central area (Fig. 1B).
