Myxomas are rare in the vocal cords. A 69-year-old man was admitted with one-year history of progressive dysphonia. Laryngoscopy revealed a polypoid mass on the right vocal cord. The diagnosis was cellular myxoma. A review of the literature including the present case revealed eleven reported cases of myxoma. Ten cases were classic myxoma. To the best of our knowledge, cellular myxoma has not been previously reported in the vocal cord. Hypercellularity does not affect the behavior of cellular myxoma. However, its recognition is important to prevent confusion with the group of low-grade myxoid sarcomas. Cellular myxoma should be considered in the differential diagnosis of any vocal cord mass.
