title: Bilateral carcinoma of the ears. Report of a case.
abstract: We report a rare case of bilateral carcinoma of the ears in a 41-year-old man. The second tumor developed from the left mastoidectomized middle ear cavity eight years after the complete healing of the first tumor, which probably originated in the glands of the right external auditory canal.
