Salmon patch in Infant/Neonate
A variant of the salmon patch known as the butterfly-shaped mark can occur in the sacral region. Sacral lesions may be associated with spinal dysraphism, tethered cord, lipomeningocele, or diastematomyelia, usually when another skin defect occurs (a dimple, sinus, swelling, excess hair, nevus, or skin aplasia).
