Disease description:

My daughter is five years old this year. Since she was born, there has been a black birthmark on her neck. As she has grown older, the birthmark has become larger as well. Recently, I noticed a few hairs growing on the birthmark, which has made me very worried. I'm afraid there might be something wrong with this birthmark. Doctor, is it normal for hairs to grow on a birthmark?

Dr. Zhou Xiaofeng

Birthmarks are common skin abnormalities in newborns and usually do not directly affect the child's health. The occurrence of hair growth on a birthmark is medically referred to as a hairy hemangioma or hairy nevus. Although this situation is relatively rare, it does not necessarily indicate a serious health risk. However, the presence of hair may suggest that the birthmark belongs to certain specific types of hemangiomas, such as mixed hemangiomas or cavernous hemangiomas, which sometimes require special attention.

It is recommended to take the child to a professional dermatologist for detailed examination and evaluation as soon as possible. The doctor may determine whether further treatment is needed based on the size, location, color, and other characteristics of the birthmark. If the birthmark is determined to be benign and without the risk of malignancy, regular observation and monitoring may be sufficient.
