Salmon patch in Child

Other Resources UpToDate PubMed


The salmon patch, also known as stork bite, angel's kiss, nevus simplex, and erythema nuchae, is the most common vascular lesion seen in infants of all races and ethnicities (20%-60%), usually at birth. The nape of the neck and occiput are the most common sites, but facial, scalp, and sacral lesions are frequent. The trunk and limbs are less often affected. There may be multiple lesions. Lesions enlarge in proportion to the child's growth. Facial lesions generally fade within 1-2 years, whereas those at other sites, especially nuchal, persist into adulthood.

A variant of the salmon patch known as the butterfly-shaped mark can occur in the sacral region. Sacral lesions may be associated with spinal dysraphism, tethered cord, lipomeningocele, or diastematomyelia, usually when another skin defect occurs (a dimple, sinus, swelling, excess hair, nevus, or skin aplasia).

Differential Diagnosis & Pitfalls

  • Port wine stain – Tend to be unilateral and do not involute past toddler age.
  • Beckwith-Wiedemann syndrome – An overgrowth syndrome associated with macrosomia, macroglossia, abdominal wall defects, and hypoglycemia in the neonatal period.
  • Nova syndrome – Salmon patches are seen on the glabellar area in conjunction with posterior fossa brain malformations.

Salmon patch is the name given to a very common group of birthmarks seen in babies. The birthmarks are caused by expansions (dilations) in tiny blood vessels called capillaries. When a salmon patch occurs on the face, it is often called an angel kiss, and when it occurs on the back of the neck, it is known as a stork bite. These types of birthmarks are very common, and at least 7 in 10 infants will be born with one or more salmon patches. Angel kisses tend to fade by age 1-2 (although some parents report that, for years, when their child cries, the angel kiss temporarily darkens and becomes apparent again), and stork bites tend to not go away at all but are usually covered by the hair on the back of the head. Salmon patches are different from port-wine stains (discussed as a separate topic) in that salmon patches do not grow larger or darker and are not associated with any syndromes involving the brain or development. Salmon patches are always noncancerous. It is sometimes difficult to tell the difference between a salmon patch and a port-wine stain.

In the past, port-wine stains and salmon patches were considered to be variations of the same kind of birthmark, but now it is now known that port-wine stains are truly malformations of capillaries and will never improve on their own, while salmon patches are temporary dilatations (expansions) of capillaries that do typically improve on their own.

Who’s At Risk

Salmon patches are very common (about 70% babies will have one or more of them) and always present at birth. It is thought that salmon patches do not run in families.

Signs & Symptoms

Salmon patches are diagnosed by their appearance. They are pink or red, flat, irregularly shaped patches that appear on the baby's face or the back of the neck. On the face, they are commonly found between the eyebrows or on one of the eyelids. Salmon patches are never painful or itchy.

Self-Care Guidelines

There is no self-care required for a salmon patch. Treat the skin as you would any other part of the baby, with careful gentle cleansing and moisturization.

When to Seek Medical Care

The skin of the salmon patch should behave just like the skin on the rest of the baby; if the skin bleeds, develops cracks, if the area becomes darker or more raised or displays any other problems, contact your child's doctor for further advice.


There is no treatment necessary for a salmon patch. Salmon patches on the face almost always go away on their own within a year or two.
