Two cases of melanotic oncocytic metaplasia occurring in the nasopharynx are reported. One presented with serous otitis media and the other with tinnitus. Nasoscopic examination revealed a small brown nodule obstructing the Eustachian tube in both cases. While oncocytic metaplasia of the nasopharynx is not too uncommon, melanin pigmentation of the nasal or nasopharyngeal mucosa is very rare. To our knowledge, their combination has not been described.
