ABSTRACT
Epidermolytic acanthoma (EA) is a rare benign tumor, which usually appears as a solitary small papule. However, there are a few case reports of multiple EA, most of which occurs on the genital area. Cases of multiple EA may mimic verruca vulgaris, condyloma accuminatum, seborrheic keratosis, and bowenoid papulosis, and therefore, can be easily misdiagnosed. A 78-year-old male presented with a 2-week history of discrete, small skin-colored papules around the anus. The other case involved a 47-year-old male with a 5-year history of skin-colored papules on the scrotum. Skin biopsy of both cases revealed a well-demarcated papular lesion characterized by compact hyperkeratosis, perinuclear vacuolization, and reticular degeneration in the granular and upper spinous layer with coarse basophilic keratohyalin granules. Epidermal invagination was consistent with a cup-shaped type of EA. Both cases tested negative for human papillomavirus. We report typical cases of multiple EA, which should be considered as the differential diagnosis of small skin-colored papules in the anogenital area, to prevent the misdiagnosis.
