Core Tip

Core Tip: Epidermolytic acanthomas (EAs) are papular skin lesions whose hallmark histologic feature is EHK. Herein, we describe a patient who presented with a solitary perianal EA and summarize the existing literature. EAs often present as pale papules in the genital region, trunk and extremities. EA is benign and cannot be spread to others, however they are commonly misdiagnosed as condyloma accuminatum, verruca, and seborrheic keratosis. Careful histopathological examination is necessary to obtain an accurate diagnosis and prevent unnecessary treatments. Although treatment of EA is not medically necessary, many patients prefer treatment, which can be accomplished with topical therapy or with excision.
