Dermoscopy of acral angioma serpiginosum

Abstract

Angioma serpiginosum (AS) is an unusual vascular disorder that typically affects female patients, begins in childhood, and stabilizes in adulthood. It not frequently involves acral skin. We herein present a 13 year-old girl with asymptomatic erythematous punctuate papules, noticed on the right palm for the last three years. During that time there was a proximal serpiginous progression up onto the forearm. Dermoscopy showed an erythematous parallel ridge pattern with some red globules and dots spreading in a linear arrangement; acrosyringial openings were not affected. Histopathological study showed dilated capillaries in the dermal papillae. These features are consistent with angioma serpiginosum (AS). This report shows a dermoscopic image of a palmar AS. The dermoscopic pattern described in this case could aid in the diagnosis of AS and could add value in diagnosing vascular lesions on acral skin.
