Frequently Asked Questions
What causes a mongolian birthmark?
Mongolian birthmarks are caused by an overgrowth of melanocytes, the pigment producing cells, deep within the skin during fetal development. This results in a high concentration of melanin pigment in a particular area of skin, producing the characteristic blue/grey markings.
Will a mongolian birthmark go away?
Yes, most mongolian birthmarks fade over the first few years of life without any treatment, although some may take longer than others. Typically they lighten significantly by age 6 but some individuals retain a lighter patch of skin or markings persisting into adulthood.
Are mongolian spots harmful to babies?
No, mongolian birthmarks are considered completely benign and harmless in the vast majority of babies. They pose no health risks or issues. Very rarely, an extremely large lesion could indicate an underlying genetic syndrome requiring evaluation.
Should you treat a mongolian birthmark?
In most cases treatment is unnecessary since the spots tend to fade on their own. However laser therapy can sometimes be used to lighten the pigmented skin, especially if the birthmark is in a visible, cosmetically concerning area or is causing psychological distress.
How can you tell a mongolian spot vs bruise?
Mongolian spots have sharply defined edges unlike the blurred margins of a bruise. They do not change in appearance over time like bruises do as they heal. Birthmarks feel smooth and flat rather than tender and swollen like bruises.
FAQs
Can mongolian spots be removed with laser treatment?
Yes, laser therapy is sometimes used to lighten or remove stubborn mongolian spots, especially those in visually prominent areas like the face or arms. However multiple treatments are usually required and results can be variable.
What is the difference between a mongolian spot and a bruise?
Mongolian birthmarks have defined borders unlike the blurred edges of a bruise. They are present at birth, remain consistent over time in color/size/shape, and feel flat rather than swollen or tender.
Are mongolian birthmarks a sign of deeper health issues?
No, in most infants they are an isolated harmless skin finding. Rarely, an unusually large and dark mongolian spot could indicate genetic conditions affecting skin pigmentation. Other congenital defects would also be present.
Do mongolian spots protect babies from the sun?
The increased melanin pigment that causes mongolian spots may offer very minimal sun protection to deeper layers of skin. However they can still sunburn so exposed areas should be protected with shade, clothing and sunscreen.
