Cutaneous manifestations of split cord malformations. Report of three cases.

A split cord malformation (SCM) is a rare congenital disorder involving a division of the spinal cord that results in two distinct hemicords divided by bone, cartilage, or a fibrous septum. Cutaneous manifestations of SCMs are common, including hypertrichosis, dimples, hemangiomas, nevi, lipomas, and sinus tracts. In this report, the authors describe cutaneous manifestations of SCMs in three patients, including a rare report of near fully formed digits overlying the SCM.
