چکیده انگلیسی
We report the case of a 52-year-old man, who was admitted in the department of otorhinolaryngology for a mass of the right parotid gland. The radiological and clinical hypothesis was a squamous cell carcinoma. Histopathological examination revealed a biphasic proliferation composed of epithelial cells arranged in a tubular pattern stained with cytokeratins 5-6 and 7 and EMA surrounded by clear myoepithelial cells stained with smooth muscle actin and p63. Ki-67 labeling index was low. The diagnosis of epithelial myoepithelial carcinoma was proposed. One year after, the patient noticed a centimetric mass of the left parotid gland. The radiological hypothesis was the presence of an intraparotidian lymph node. Histopathological examination showed a second epithelial myoepithelial carcinoma. This is an uncommon neoplasm comprising approximately 1% of all salivary gland tumours, affecting mainly the parotid gland. It is occurring preferably in patients older than 60Â years old. This is a low-grade malignant tumour with tendency to local recurrence and lymph node metastatic potential. We describe an exceptional bilateral epithelial myoepithelial carcinoma of the parotid gland.
