[Naevus unius lateris: a confusing entity (a case report)].

Naevus unius lateris is a rare congenital hamartoma, originating from the ectoderm. It is considered as a verruquous variant of the epidermal naevus. Given its extensive unilateral distribution, it is frequently associated with neurological, musculoskeletal, auditory and visual abnormalities. We here report the case of a 9-year-old child with nevus unius lateris associated with neurological and eye abnormalities.
