Abstract
|
|
|
|
Epidermolytic acanthomas (EA) are uncommon benign tumors clinically presenting as single to multiple papules. Histologically, EA display hyperkeratosis, hypergranulosis, acanthosis, and epidermal degeneration?also known as epidermolytic hyperkeratosis (EH). EA may be misdiagnosed as condyloma both clinically and histopathologically when located on the genitalia. Thus, this diagnosis carries a significant psychological burden and must remain in the differential when initially considering genital warts. We utilize the case of a 62-year old female referred to dermatology for a 5-year history of multiple pruritic and hypopigmented vulvar papules?misdiagnosed as genital warts?to highlight the impact of differentiating EA from genital warts. This patient was initially misdiagnosed with common genital warts at her gynecologist’s office and treated unsuccessfully for years. A shave biopsy was performed and histology revealed EH, consistent with EA.
