Localized epidermolytic hyperkeratosis of the female genitalia: a case report and review of an underappreciated disorder of women.

Epidermolytic hyperkeratosis (EHK) is a distinct pathologic entity that may present as a generalized congenital disorder. A localized form occurring only upon the female genitalia may not be well appreciated by clinicians dealing with women. EHK of the female genitalia is a rare diagnosis, with just 6 cases reported within the indexed literature. Clinically, it may resemble condyloma, although involvement of human papillomavirus has never been demonstrated. Providers unfamiliar with this entity may be further confused by reports of the histopathologic features. Herein, we describe a case and review the literature with respect to EHK of the female genitalia. Familiarity with this condition is desirable, as confusion with condyloma is likely, yet the prognosis is decidedly different.
