Faun tail nevus with aplasia cutis congenita.

Faun tail nevus describes abnormal lumbar hypertrichosis, which may overlie on occult spinal abnormality and be a marker of asymptomatic underlying spinal dysraphism. We report a case of faun tail nevus, with dermal pits along with aplasia cutis congenita and asymptomatic spina bifida occulta, tethered conus, and diastematomyelia, a constellation of findings which to our knowledge has not been previously reported.
