Adenocarcinoma of the larynx.
Adenocarcinomas make up less than one per cent of laryngeal malignancies. Nonspecific adenocarcinomas and adenoid cystic carcinomas comprise most of the glandular neoplasms. Adenoid cystic carcinoma has a slight preponderance in females, and often follows a long course similar to this tumor when it occurs in salivary glands. The nonspecific adenocarcinomas occur predominately in males and have a low survival with most patients dying within two years. Less common adenocarcinomas include oncocytoid carcinoma, mucoepidermoid carcinoma, and metastatic adenocarcinoma.
