[Undifferentiated carcinoma of nasopharyngeal type sitting in the hypopharynx].

Nasopharyngeal-like carcinoma is an extremely rare tumor when localised in the laryngopharyngeal mucosa. Only 10 of such tumors could be found by the AA. in the medical literature. They report this additional case in which the radiotherapy plus the chemotherapy have controlled, till now, the primary disease and its spreading to the cervical lymph nodes.
