A 54-year-old male with a hypopharyngeal squamous cell papilloma and a 67-year-old male with a hypopharyngeal cavernous hemangioma are reported. Neither had symptomatic complaints and the tumors were found incidentally in both cases. Direct laryngoscopy was performed and the papilloma which had a long stalk on the posterior hypopharyngeal wall, was removed. The papilloma was suspected to be a virus associated tumor on the basis of koilocytosis but no human papillomavirus was detected immunologically. Lateral pharyngotomy was performed and the cavernous hemangioma was removed from the left pyriform sinus. The pertinent literature on benign hypopharyngeal tumors is reviewed.
