Abstract
Two cases of carcinosarcoma of the hypopharynx were presented. The first patient was a 52-year-old female complaining of dysphagea. Laryngofiberscopy and pharyngography revealed a round mass arising from the posterior wall of the hypopharynx and occupying about half of the lumen. The tumor was completely excised with part of the pharyngeal wall using right iateral and suprahyoid pharyngotomy. Histopatholgical examination revealed a so-called carcinosarcoma. The second patient was a 75-year-old male complaining of dysphagea and dyspnea. Laryngofiberscopy and CT scan revealed a round mass arising from the right pyriformis sinus and almost obstructing the supraglottic space. Because of post cricoid invasion, the tumor was completely excised along with the larynx. Histopathological examination revealed a carcinosarcoma. To date, there has been no evidence of local recurrence or metastasis in either case. Previously, only 7 cases of carcinosarcoma of the hypopharynx have been reported in Japan.
