Hairy, abnormally pigmented skin on lumbosacral region

Patients with spinal cord tethering syndrome, especially children, should be alert to a clinical manifestation of the disease: lumbosacral skin is hairy and abnormally pigmented. Tethered cord syndrome (TCS) is a syndrome that causes a series of neurological dysfunction and deformity due to various congenital and acquired causes of the spinal cord or cone being stretched. Because the spinal cord is stretched in the lumbosacral spinal cord and causes abnormally low cones, it is also called the low spinal cord.
