Question
How can one differentiate between the pale red spots on a newborn’s forehead, upper eyelid, and back of the head, determining whether they are neonatal moles or port wine stains?
Answer
Port wine stains, also known as strawberry marks, are congenital capillary malformations characterized by flat, well-defined spots that may fade when pressed. They can range in size from small to large, extending from localized areas to even half of the body. Neonatal moles are typically smaller, more often pale red, and also fade upon gentle pressure. The main difference between the two is that port wine stains tend to be larger and may become more prominent as the child grows older.
