Mucoepidermoid carcinoma of the air passages: report of three cases.

A review of the literature on tumors of the small salivary and mucous glands reveals that mucoepidermoid carcinoma of the upper respiratory system is a very rare occurrence. Three such cases are reported in detail, representing 3% of all tumors of small salivary and mucous gland origin recorded by the authors over a period of 20 years. This incidence is high. Follow-up was from 3 to 12 1/2 years.
