Occult dysraphism presenting with acro-osteolysis.

The skin and the nervous system share common embryologic origins. Cutaneous stigmata may be early clues to underlying occult spinal dysraphism. The delayed manifestations of spinal dysraphism may also involve the skin. We report a case of a 4-year-old child in whom acro-osteolysis and cutaneous trophic changes on the right foot were the presenting features of occult dysraphism.
