Patient's question:
Detailed medical condition and consultation purpose: There are light red spots on the forehead and upper eyelids that do not protrude from the skin surface and fade upon light pressure. There is also a spot on the back of the head. I am unsure if they are neonatal nevi or salmon patches. Additionally, how can I differentiate between salmon patches and neonatal nevi?Doctor's answer:
Port wine stain, also known as a red birthmark, is the second most common type after strawberry hemangioma. It is a relatively flat and slightly elevated plaque composed of numerous dilated capillaries and belongs to congenital capillary malformation. The symptoms of port wine stain can vary in size, with larger ones potentially covering almost the entire face or half of the torso. Often, it appears as a distinct pink, flat, and well-defined plaque at birth, which fades under pressure.
