Introduction

Epidermal nevus (EN) is a hamartomatous proliferation of keratinocytes. It usually appears during the first year of life and gradually increases in thickness, although some cases of late-onset development have also been reported ¹. EN is usually an isplated benign lesion, but especially when it is extensive, it may be associated with other organ and system abnormalities which is called epidermal nevus syndrome².
Dermoscopy is a non-invasive diagnostic method that can be used readily to differentiate melanocytic and non-melanocytic lesions. It also helps in biopsy decision making for a suspected lesion ²´³.
Herein we report an acquired case of EN in a 32-year-old woman with epidermolytic hyperkeratotic pattern and present a review of the literature about it.
