New type of epidermal nevus syndrome

Abstract

An uncommon type of epidermal nevus characterized by systematized bands of non-epidermolytic hyperkeratosis with increased hairiness and follicular hyperkeratosis was observed in a 16-year-old boy who showed, in addition, hemihypoplasia of limbs, brachydactyly, clinodactyly and onychodystrophy. This case cannot be categorized within the group of presently established epidermal nevus syndromes. Most likely, this combination of anomalies represents a new type of epidermal nevus syndrome.
