[Myoepithelial-epithelial carcinoma of the parotid: cyto-histological description of a case].
We report a case of epithelial-myoepithelial carcinoma of the parotid gland arised in a 72 years-old woman, in which the diagnosis was suspected on fine-needle aspiration and confirmed on surgical specimen. Immunohistochemical evidence for the dual differentiation (glandular and myoepithelial) of the tumour was obtained both on surgical specimen and cytological inclusion. Morphological features and proliferating index (MIB1) analysis suggest that this case is an intermediate grade malignant neoplasm. Main differential diagnosis of the epithelial-myoepithelial carcinoma with predominantly clear cell tumours of the salivary glands were discussed.
