History:

There are many causes of localized congenital hypertrichosis such as hypertrichosis cubiti (hairy elbows), congenital nevocytic nevi, anterior cervical hypertrichosis, and simple nevoid hypertrichosis. Localized hypertrichosis may be a sign of underlying spinal dysraphism when it occurs over the sacral midline. Fortunately, the presented case had no associated spina bifida.
