Apocrine epithelial-myoepithelial carcinoma of the parotid gland with concurrent oncocytic change: A novel variant
Epithelial-myoepithelial carcinoma (EMCa) is a rare, low-grade, malignant salivary gland tumor. Herein, we report an unusual case of an EMCa with extensive apocrine and oncocytic changes. The tumor occurred in the left parotid gland of a 68-year-old male. Histologically, the tumor was characterized by a biphasic arrangement of luminal ductal cells and abluminal polygonal myoepithelial cells with prominent apocrine differentiation in the luminal layer and dense eosinophilic cytoplasm in both components.
