We report the case of an 11-year-old girl who presented with a soft-tissue mass that filled the left external auditory canal and a discharge that resembled chronic suppurative otitis media. The patient underwent mastoid exploration with complete excision of the mass. Findings on the excision biopsy were consistent with a myxoma of the temporal bone. At follow-up 2 years postoperatively, the patient remained disease-free. To the best of our knowledge, this is only the 12th case of a myxoma of the temporal bone to be reported in the English-language literature.
