Mucoepidermoid carcinoma of the larynx.

We report two cases of poorly differentiated mucoepidermoid carcinoma of the larynx which both remain well after surgical management. The first underwent a radical neck dissection for recurrent disease following radiotherapy and the second a total laryngectomy with elective post-operative radiotherapy. Although well differentiated ('low grade') mucoepidermoid tumors of the larynx may respond to radiotherapy surgical management is generally recommended for all grades of such tumours especially for poorly differentiated ('high grade') tumours. Elective post-operative radiotherapy is often advocated for high grade tumours; radical neck dissection is generally undertaken only in the presence of lymphadenopathy, although elective radical neck dissection has been proposed for high grade tumours. These cases emphasise the value of comprehensive surgical management for this condition. Such laryngeal tumours are difficult to diagnose histologically from biopsy and are often initially reported as squamous cell carcinoma.
