Birthmarks – red

Alternative Names

Strawberry mark; Vascular skin changes; Angioma cavernosum; Capillary hemangioma; Hemangioma simplex

Definition of Birthmarks – red

Red birthmarks are colored, blood vessel (vascular) skin markings that develop before or shortly after birth.

Causes, incidence, and risk factors

There are two main categories of birthmarks.

Signs and tests

A health care provider should examine all birthmarks. Diagnosis is based primarily on the appearance of the skin lesion.


Many strawberry hemangiomas, cavernous hemangiomas, and salmon patches are temporary and do not need treatment.

Expectations (prognosis)

Birthmarks rarely cause problems, other than cosmetic changes. Many birthmarks go away on their own by the time a child is of school age, but some are permanent.
