Intradermal melanocytic nevi are usually asymptomatic, but a patient with such a lesion in the external auditory canal can present with aural obstruction and conductive deafness.

     A 58-year-old woman presented to our clinic with left aural obstruction and a mild hearing loss of several months’ duration. Aural pruritus and intermittent bloody otorrhea following ear picking were also noted. Otoscopy showed a pink, papillomatous mass measuring 0.5 × 0.5 cm over the anteroinferior cartilaginous aspect of the external auditory canal (EAC) (figure 1). The tympanic membrane was normal.
