Synopsis
Angioma serpiginosum is a benign vascular malformation that usually presents within the first two decades of life. It is more common in young females. It begins as small areas of red or violet-colored macules and papules that start to coalesce over a period of several years to achieve a "serpiginous" appearance overall.
