A 42-year-old woman presented with multiple, asymptomatic, dark, raised lesions involving both her ears. The lesions appeared 1 year ago in her left ear and subsequently involved her right ear. There was no history of arthralgia, oral ulcers, photosensitivity, or alopecia. Review of the systems was unremarkable. On examination, the lesions were bilateral, discrete to confluent, monomorphic, 1-2 mm in diameter, firm, hyperpigmented, and papular involving the auricular conchae and the external auditory meatus. The helix and the crura of the antihelices were spared [Figure - 1]. There was no obstruction of the canals on otoscopic examination. Biopsy from the right ear revealed a hyperplastic epidermis and globular masses in the dermal papillae. No evidence of interface dermatitis was demonstrated [Figure - 2]. Routine laboratory investigations including complete blood count, blood sugar levels, renal and hepatic and urinary analysis were within normal limits.
