During a 20-year period, 12 patients with nontraumatic, nonneoplastic subglottic stenosis were seen at the Mayo Clinic. The etiologic factors were relapsing polychondritis, amyloidosis, sarcoidosis, and Wegener's granulomatosis. Because of the diverse initial presentation of the disease, the clinician should consider that the stenosis is a manifestation of a systemic disorder and carry out an otolaryngologic and physical examination with the appropriate roentgenograms and blood and urine tests. Treatment, if a systemic disease is proved, consists of appropriate medication. Surgery may be necessary, depending on the nature of the lesion. Small strictures may not need to be treated.

Granular cell tumors of the larynx.

Granular cell tumors of the larynx are relatively uncommon, always benign, and most commonly located in the posterior portion of the larynx. They are easily identified and should be differentiated from other lesions. A possible problem in the differential diagnosis is the presence of pseudoepitheliomatous hyperplasia, which overlies the granular cell tumor and which may mimic squamous cell carcinoma. Careful histopathologic differentiation is important because the laryngeal granular cell lesion should be managed conservatively, with transoral local excision usually being adequate. The histogenesis of these lesions remains in doubt, with a neural or epithelial derivation being the most likely possibility.

Granular cell tumors of the tongue.

We have presented a series of 19 new cases of granular cell tumors of the tongue. This benign condition is often difficult to diagnose if an adequate biopsy specimen has not been obtained. Insufficient biopsy material that includes only the overlying pseudoepitheliomatous hyperplasia may distort the pathologic picture. Review of frozen sections should provide an accurate diagnosis, and local surgical excision should resolve the problem completely.

Laryngofissure and cordectomy for early cordal carcinoma: outcome in 182 patients.

At the Mayo Clinic from 1962 to 1974, 182 patients with early squamous cell cancer of the true vocal cord were treated by laryngofissure and cordectomy. Seven patients (4%) had recurrences: four in the larynx and three in the neck (although the larynx was free of disease). The case histories of these patients are reported. Only three (2%) of the patients died as a consequence of their laryngeal cancer. The data substantiate our belief that the laryngofissure and cordectomy operation, and its minor variations, is an expeditious and highly successful means of eradicating glottic cancers.

Mucoepidermoid carcinoma of the oral cavity.

From 1950 through 1975, 54 patients with mucoepidermoid carcinoma of the oral cavity were treated at the Mayo Clinic. Metastatic disease occurred in 13 patients; nine patients died of their disease. Mucoepidermoid tumors of the hard palate should be treated by partial maxillectomy. Complete neck dissection is necessary for tumors larger than 2 cm in the base of the tongue. Other intraoral mucoepidermoid carcinomas are treated by wide surgical excision.

Chondrosarcoma of the nasal cavity, paranasal sinuses, and nasopharynx.

Thirteen patients, six men and seven women, were seen at the Mayo Clinic with chondrosarcomas of the nasal cavity, paranasal sinuses, or nasopharynx in a 25-year period. Nasal obstruction, discharge, and bleeding were the major symptoms and a nasal mass was the most common sign. The typical chondrosarcoma is low in grade but malignant and it arises in the nasal cavity as a large, pale, glistening mass. Local excision was employed initially in seven patients and five had local recurrence. Definitive block excision cured four of six patients and the two others had a protracted clinical course and ultimately died of the disease. Long-term follow-up shows that chondrosarcomas are insidious, locally progressive tumors. Radiotherapy, used for palliation after recurrence, failed to produce any cures. Lateral rhinotomy and block excision are advocated as the primary treatment.
