Salivary duct carcinoma of the larynx: Report of a rare case

Abstract

Salivary duct carcinomas are primarily high-grade, aggressive malignancies that affect men in the fifth and sixth decades of life. These tumors are usually found in the major salivary glands; rarely do they originate in the minor salivary glands. The distinctive feature of these neoplasms is their remarkable histologic resemblance to infiltrating ductal carcinomas of the mammary gland; both types of tumor feature epithelial and myoepithelial cells arrayed in solid, papillary, and cribriform patterns. To the best of our knowledge, only one case of a primary salivary duct carcinoma of the larynx has been previously reported. In this article, we describe a new case, and we review the literature on salivary duct carcinomas.
