What are the types of red birthmarks?

One common kind of vascular birthmark is the hemangioma. It usually is painless and harmless and its cause is unknown. Color from the birthmark comes from the extensive development of blood vessels at the site.

Strawberry hemangiomas (strawberry mark, nevus vascularis, capillary hemangioma, hemangioma simplex) might appear anywhere on the body, but are most common on the face, scalp, back, or chest. They consist of small, closely packed blood vessels. They might be absent at birth, and develop after several weeks. They usually grow rapidly, remain a fixed size, and then subside. In most cases, strawberry hemangiomas disappear by the time a child is 9 years old. Some slight discoloration or puckering of the skin might remain at the site of the hemangioma.

Cavernous hemangiomas (angioma cavernosum, cavernoma) are similar to strawberry hemangiomas but are more deeply situated. They might appear as a red-blue spongy mass of tissue filled with blood. Some of these lesions disappear on their own, usually as a child approaches school age.

Port-wine stains are flat, purple-to-red birthmarks made of dilated blood capillaries. These birthmarks occur most often on the face and might vary in size. Port-wine stains often are permanent (unless treated) and might thicken or darken over time, resulting in emotional distress.

Salmon patches (also called stork bites) appear on 30 percent to 50 percent of newborn babies. These marks are small blood vessels (capillaries) that are visible through the skin. They are most common on the forehead, eyelids, upper lip, between the eyebrows, and the back of the neck. Often, these marks fade as the infant grows.
