Blaschkolinear angioma serpiginosum: a rare vascular anomaly

Abstract

Angioma serpiginosum (AS) is a rare, benign, nevoid vascular anomaly that usually starts in childhood or early adolescence with a predilection for extremities and spares mucosal areas. The blaschkolinear variant of this condition has rarely been described in the literature. We report a case of AS in a unique blaschkolinear configuration and discuss the dermoscopic differentials for dermatoses with similar presentation.
