Linear epidermolytic acanthoma of vulva: an unusual presentation.

Epidermolytic acanthoma (EA) is a rare benign tumor that shows epidermolytic hyperkeratosis (EH) on histopathology. It can occur in a solitary or disseminated form. This condition needs to be distinguished from other hereditary or acquired conditions that may show EH. We diagnosed an unusual case of EA of the vulva presenting in a linear pattern in a 50-year-old lady based on the clinical features and typical histopathological findings and stress the importance of considering epidermolytic acanthoma in the differential diagnosis of verrucous lesions of the genitalia.
