[Osteosarcoma of the larynx].

The authors present a case of rare laryngeal neoplasm--osteosarcoma, which generated many diagnostic and treatment difficulties. Its main cause was nonspecific symptoms and laryngoscopic view, positive tuberculous history and positive tuberculosis tests. The first histopathological examination was "angioleiomyoma exulcerans, chronic inflammation and granulation." No cancer nor tuberculosis was found". After the physiologic consultations and with positive tuberculin test the tuberculocidal treatment was applied, but it bought no success. The larynx was split then, intraoperative histopathological examination gave the result: "Cellulae carcinomatosae". The total laryngectomy was performed. Postoperative immunohistochemical examination was "Osteosarcoma of larynx". The patient was not evaluated for radio- or chemotherapy. Admitted to the hospital after 5 months with neck tumor and reactional lymph nodes by the right side of the neck. Crile's operation was performed. During the postoperative course some metastatic lymph nodes on the left side of the neck and in lungs were detected. Patient noted to chemotherapy.
