Clinicopathologic study and classification of vocal cord cysts.

Cysts of the true vocal cords are less common than other laryngeal cysts. They are usually easily recognized and managed. Patients present with complaints of hoarseness and/or dyspnea. We report our experience with 41 cases of cysts located in the true vocal cords. Clinical and histological aspects are reviewed and discussed. A new histological classification is proposed: A: cysts lined by columnar epithelium with mucous content; B: lined by columnar epithelium with cilia; C: lined b squamous epithelium without keratinization; D: lined by squamous epithelium with keratinization.
