Asymptomatic Plaques on the Bilateral Postauricular Areas in a 50-year-old Man

Case report A previously healthy 50-year-old fisherman had asymptomatic erythematous lesions on the bilateral postauricular areas for 18 months. He denied the history of applying any topical agents or taking any systemic drugs. There was no history of photosensitivity, burn, irradiation and local trauma in the areas. None of his family had a similar problem. The skin examination showed multiple white, 1 to 2 mm papules within erythematous plaques on the bilateral postauricular areas (Fig. 1). A biopsy was taken and the tissue specimen was stained with H & E stain (Fig.2).
