After birth, parents will easily notice that babies will have small or more patches of blue purple skin on certain parts of their body, especially on their waist, back, and buttocks, where there will be more blue purple patches. So, what's wrong with a 2-year-old baby having bruises on their buttocks?
The appearance of cyanosis on the buttocks of a baby is medically referred to as "congenital dermal melanocytosis". For unknown reasons, parents may think that this name is quite scary, but in fact, it is commonly known as Mongolian spots, which are innate pigmentation. This type of pigment deposition is more common in babies' waist and back, and it will gradually fade or even disappear as the baby grows and develops. In rare cases, it may persist or even expand in size. Therefore, parents do not need to worry.
The bluish purple scars on babies may darken in color for a period of time after birth, which is not common, but they will gradually decrease or even disappear afterwards. So, parents don't have to spend a lot of effort taking their babies for treatment everywhere.
The appearance of bluish purple scars is usually present at birth, commonly in the lumbar and sacral regions, buttocks, and is generally circular or oval in shape. The colors are bluish purple, light blue, light brown, etc. Within a few years of birth, they will automatically fade or disappear without any trace. If the baby's scars do not fade after five weeks, it is recommended to consider going to the hospital for examination to rule out the possibility of skin lesions.
