Hemangioma Definition & Overview

Definition

A hemangioma is a type of birthmark, usually on the head or neck, which appears shortly after birth, grows rapidly, and in most cases slowly disappears, usually before puberty. The mark is a cluster of blood vessels that form abnormally.

If your child develops a birthmark that grows, consult a doctor. This is a potentially serious condition that may require medical treatment to allow proper development of nearby organs.
