Salmon patch; Nevus flammeus
A stork bite is a common type of birthmark seen in a newborn. It is most often temporary.
The medical term for a stork bite is nevus simplex. A stork bite is also called a salmon patch.
Stork bites occur in about one third of all newborns.
A stork bite is due to a stretching (dilation) of certain blood vessels. It may become darker when the child cries or room temperature changes. It may fade when you push on it.
