Extramammary Paget’s disease is a neoplastic disease, which usually manifests as an erythematous plaque on the genital area. Pigmented extramammary Paget’s disease is a rare variant. It should be differentiated from malignant melanoma. We report a case of pigmented extramammary Paget’s disease in a 62-year-old male who had a brown-to-black or erythematous-colored plaque on the scrotum and inguinal area. Histopathologic findings showed features typical to extramammary Paget’s disease, with proliferation of epidermal melanocytes and dermal melanin pigments.
