Epidermal nevi: a retrospective study of 133 cases

Epidermal nevi are common skin dysembryoplasias that may be present at birth or develop during early childhood. Clinically they are hyperkeratotic, verrucous lesions, which, if associated with skeletal, neurological and ocular abnormalities conform an epidermal nevus syndrome. We present 133 cases among which the most frequent clinical presentation was nevus simplex followed by ILVEN. The predominant histological feature was the classic pattern, followed by the epidermolytic hyperkeratosis pattern. The prevalence of the epidermal nevus syndrome was 2.21%. (Dermatol. Argent. 2011; 17(1):40-46). Key words: epidermal nevus, verrucous nevus, epidermal nevus syndrome
