Abstract
Verrucous epidermal nevi are hamartomatous lesions of the epidermis that, unlike
other epidermal nevi (such as sebaceous nevus or nevus comedonicus), are rarely
associated with malignant neoplasms. The majority of squamous cell carcinoma
develop in linear or multiple epidermal nevus and rarely in solitary epidermal
nevus. In general, the prognosis is favorable. We report a case of
well-differentiated invasive squamous cell carcinoma arising from a multiple
verrucous epidermal nevus. Although there is no consensus on prophylactic
removal of epidermal nevus, its removal and biopsy should be considered if
changes occur.
