Abstract

Epithelial-myoepithelial carcinoma (EMC) is a rare type of low-grade malignant tumor that account for approximately 0.5% to 1% of salivary gland neoplasm and arises most commonly in the parotid gland (80%). We introduce three cases of parotid EMC arose as painless cystic mass in male patients over 70 years old. All patients were diagnosed as benign tumors (pleomorphic adenoma) by image and pathologic study (fine needle aspiration) before surgery, but the final histopathologic results were EMC. All three patients underwent parotidectomy without adjuvant radiotherapy. There were no complications such as facial paralysis. No complications or recurrences were observed during follow-up for 6 to 9 months. Since the reports of EMC are still relatively few, we report our three cases with the clinical and pathological review.
