A pit or indentation in the skin on the lower back known as a sacral dimple is present in certain newborns at birth. Typically, it is located slightly above the line between the buttocks. The majority of sacral dimples are benign and don’t require treatment.
If the sacral dimple is significant or appears next to a hair tuft, skin tag, lump, or discolored area, it may indicate a major spinal issue in a newborn. The doctor who is caring for your child may advise an imaging test in certain circumstances. Treatment for spinal issues depends on their initial cause.
