Angioma Serpiginosum: Clinico-dermoscopic Histopathology Correlation

Angioma serpiginosum (AS) is an uncommon vascular anomaly with unknown etiopathogenesis. It typically presents as asymptomatic unilateral red-colored macules and papules in linear serpiginous pattern during the first two decades of life. It most frequently affects lower limbs followed by gluteal area. We present a case of AS affecting primarily one-half of the trunk and the ipsilateral limb. The diagnosis was confirmed with dermoscopy that revealed characteristic well-defined round-to-oval red lagoons representing dilated capillaries in the papillary dermis on histopathology.
