Dermoscopy of acral angioma serpiginosum


Angioma serpiginosum (AS) is an unusual vascular disorder that typically affects female patients, begins in childhood and stabilizes in adulthood and not frequently involve acral skin. We herein present a 13 year-old girl with an asymptomatic erythematous punctuate first noticed on the right palm three years ago, with a proximal serpiginous progression up to the forearm. On examination there was a nonblanching erythematous punctuate on the palm and the inner aspect of right hand and forearm. Dermoscopy showed an erythematous parallel ridge pattern with some red globules and dots spreading on a linear arrangement, and the acrosyringia openings were not affected. Histopathological study showed dilated capillaries in the dermal papillae. This feature is consistent with angioma serpiginosum (AS). To the best of our knowledge, this is the first report that 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 a value in the differential diagnosis with vascular lesions on acral skin.
