title: An intradermal nevus of the external auditory meatus.
abstract: We herein describe a rare case of an intradermal nevus arising in the external auditory meatus. A 36-year-old woman presented with progressive hearing loss on the right ear, and otomicroscopic examination revealed the presence of a large, violaceous, dome-shaped, papillomatous lesion originating from the posterior wall of the external canal of the right ear. Upon excisional biopsy, the tumor was diagnosed as an intradermal nevus. Thus, this is a unique case of intradermal nevus obstructing the external ear canal with the patient presenting with progressive hearing loss. The possibility of a benign nevomelanocytic nevus should not be underestimated when evaluating a lesion obstructing the ear canal, and all melanocytic nevi should be excised instead of biopsied to rule out melanoma.
