✦ Synopsis

Abstract

Background

Ipsilateral salivary gland tumors of different histologic types are rare and make up less than 0.3% of all salivary gland neoplasms. Only nine cases of synchronous benign and malignant ipsilateral parotid gland tumors have been described in the literature.

Methods

Two additional cases of synchronous benign and malignant neoplasms in the parotid gland are reported and discussed with a review of literature.

Results

Our first case describes a pleomorphic adenoma and a salivary duct carcinoma, an entity not previously reported in the literature. The second case documents the most common benign and malignant ipsilateral parotid gland neoplasm reported in this case series, a Warthin's tumor and a mucoepidermoid carcinoma.

Conclusions

Synchronous salivary gland tumors exhibiting both benign and malignant components are uncommonly observed, with only nine cases published to date. We describe two additional cases of a synchronous benign and malignant ipsilateral parotid gland tumor. Β© 2002 Wiley Periodicals, Inc. Head Neck 24: 301–306, 2002; DOI 10.1002/hed.10048
