Which statement about Mongolian spots is true?

• A. They are bluish discolorations that fade by 1-2 years and are normal; document to distinguish from bruises
• B. They indicate abuse and require investigation
• C. They require immediate skin biopsy
• D. They are permanent birthmarks present at birth

Answer: (A)

Mongolian spots are a benign congenital dermal melanocytosis. They appear as bluish-gray patches, usually on the lower back or buttocks, and are common in newborns, especially those with darker skin. They typically fade over the first year or two of life without any treatment, which is why documenting their presence helps distinguish them from bruising or other injuries. They do not indicate abuse and do not require biopsy or any intervention. These patches are not permanent birthmarks; they usually disappear by early childhood.
