Mongolian blue spots
Mongolian spots are blueish-grey spots that are found on the lower back of infants.
The name came about because these spots were first described in Mongolian children, but they are unrelated to Down’s Syndrome.
These spots are a result of a cessation of migration of melanin pigmented cells in the dermis layer of the skin that occurs during fetal life.
The spot is commonly found in children with dark skin (up to 80% prevalence) and in about 10% of children from White decent. It is also common in children from eastern descent.
What do Mongolian blue spots look like?
Mongolian spots are blueish or grey in colour, have clear margins and are found in the sacral region (lower back) of infants, but may also be found in other areas of their bodies.
They can be small or large in size (see attached image).
What happens to Mongolian spots over the years?
In the first year of life, these spots can become darker but afterwards, they often fade and disappear within a few years.
Multiple, large spots that are found in less common areas of the body tend to stay. Nonetheless, these spots rarely require laser treatment.
Should I be worried about my baby’s Mongolian spot?
Absolutely not. It is a common finding that is almost always isolated and does not indicate any sort of medical condition. If your baby has a Mongolian spot but is otherwise cute, healthy and growing well, there is absolutely no reason to be worried or to seek medical attention because of this finding.
