Successful treatment of angioma serpiginosum using a novel 532 nm potassium titanyl phosphate (KTP) laser.

Angioma serpiginosum (AS) is a rare, benign, vascular disorder comprising non-blanchable punctate red to purple lesions in a gyrate or serpiginous configuration. We report a case of a 38-year-old woman with a red colored eruption on her chest which was present since puberty. A novel 532 nm potassium-titanyl phosphate (KTP) laser (Excel V, Cutera Inc., Brisbane, CA, USA) was applied which resulted in near complete resolution after two sessions of treatment.
