Mucoepidermoid carcinoma of the larynx.

Two cases of mucoepidermoid carcinoma (MEC) of the larynx are reported. The peculiarities of both cases are emphasized, in particular the site of involvement and the young age of the former and the histological subtype ('clear cell' variant) of the latter. The microscopic differential diagnosis of MEC and its biological behavior according to the grade of differentiation is discussed. The available literature is reviewed. [ABSTRACT FROM AUTHOR]
