Western Summary

A slate gray macule is an area of gray/blue skin most often found on the low back or buttocks of newborns.  

These lesions were previously known as "Mongolian spots" which has now dropped out of favor because of its derogatory nature

Symptoms

Typically there are no symptoms associated with the slate-gray macule as they are not painful or itchy. 

Causes

This appearance is due to pigment within the mid layer (dermis) of skin. Certain ethnic groups are more likely to have a slate grey macule present at birth. 

 

Treatments

No treatment is required, but certain lasers that target pigment can be used to make the pigment that is causing the slate grey macule less visible.
