Salmon patch, also known as naevus simplex, is a type of birth mark that presents as a flat patch of pink or red skin. They become darker red with crying and turn pale when pressure is applied to the skin. Areas commonly involved include around the eyes, scalp, and neck. It is not associated with pain.
It occurs as a result of small blood vessels in the skin widening. Diagnosis is based on the appearance. When it affects the back of the neck it is known as a stork bite and when it occurs around the nose or eyes it is known as an angel's kiss. They are not technically naevi.
They often improve and resolve by two years of age; though, when the back of the neck is involved about half of cases remain to some degree. Laser therapy may be used in cases that do not resolve. Regardless the condition is not serious.
