Diffuse hypertrichosis and faun-tail naevus as cutaneous markers of spinal dysraphism

We describe two cases of spinal dysraphism where detection of the cutaneous signs - namely a faun-tail naevus and diffuse hypertrichosis - led to early recognition of the occult neurological abnormalities and institution of corrective surgery. The dermatologist may be the first physician to observe these skin changes and an early neurosurgical referral can prevent subsequent neurological complications.
