[Diagnosis and treatment of rare tumors in the laryngeal-pharyngeal area (author's transl)].

From 1968 to 1979, 11 patients with rare tumors in the laryngeal-pharyngeal area have been treated by the Department of otolaryngology at the University hospital Homburg-Saar. These 11 cases consist of 6 benign and 5 malignant tumors. The malignant tumors were irradiated postoperatively by the Department of Radiology. There was found in the pharyngeal area 1 malignant despeciated leiomyoma, 2 malignant synovialomas and in the laryngeal area 4 local nongeneralised amyloidosis, 1 hamartoma, 1 chemodectoma, 1 pleomorphic rhabdomyosarcoma of the larynx and 1 primary "oat-cell" carcinoma. The initial exploratory excisions often led to an incorrect diagnosis: The final one was made postopertively. The large number of preoperative wrong diagnoses leads to the demand to only operate after extensive exploratory excisions.
