Mongolian spots may also grow on the face.
1. Mongolian spots are congenital dermal melanocytosis, which is a birthmark that babies are born with, and the melanocytes can be seen in the deep dermis histologically, so it can also be called dermal melanosis clinically.
2. Mongolian spots can occur in any part of the body, so they can also appear on the face, but clinically they are more common in the lumbosacral region and buttocks. It can be grayish green, blue or blue-black, round, ovoid or irregular, with a diameter ranging from several millimeters to more than ten centimeters.
3. Mongolian spots usually disappear at the age of 5-7 years and leave no traces, but some children may persist into adulthood or have an enlarging phenomenon. For children with generalized spots that do not go away for a long time, interrupted pulsed light, such as Q-switched ruby, can be used for treatment.
It is recommended to go to the hospital once the Mongolian spots appear abnormal and be treated under the guidance of the doctor.
