The variety of oral involvement present in this group of epidermal nevi seems not to be generally well known. The dermatological textbooks note the occurrence of oral involvement, but do not describe the changes in detail. Conversations with dermatologists with wide experience indicate that this report has something new to offer in bringing together the sites and types of changes of the oral lesions.
