Background. Epithelial-myoepithelial carcinoma (EMC) of the salivary gland is a low-grade carcinoma. It has been widely accepted as a clinicopathologic entity only in the past decade. Histologically, the classical bimodal differentiation of inner eosinophilic ductal cells and outer layer of clear my

Abstract
A 63βyearβold man was initially seen with multiple pulmonary nodules 14 years after a left parotidectomy for an epithelialβmyoepithelial carcinoma of salivary gland. Eight and 18 months after parotidectomy, the patient had local recurrence of his salivary gland tumor. He remained diseaseβfree before being seen with pulmonary nodules, which were evaluated by open lung biopsy. The pathologic features of the pulmonary nodules were identical to the salivary gland tumor resected 14 years earlier. This is the fourth reported case of epithelialβmyoepithelial carcinoma of salivary gland metastasizing to a distant site. Β© 1992 John Wiley & Sons, Inc.

The salivary glands are the site of many neoplasms characterized by a mixture of epithelial and myoepithelial cells and stromal fragments. Cytologic distinction of these neoplasms may be very dificult but careful attention to cellular details and the interaction between the cells and stronia can cor
