Abstract/OtherAbstract:
Epithelialmyoepithelial carcinoma (EMEC) is a rare low-grade malignant salivary gland neoplasm that most commonly occurs in the parotid gland but can also arise in minor salivary glands. Here, we present a case of EMEC in a 60-year-old male patient with a huge swelling in the left parotid gland region. Clinically and radiologically, it simulated a benign salivary gland neoplasm. However, fine-needle aspiration cytology and histologic examination revealed atypical myoepithelial cells in solid sheets or nests suggestive of epithelial-myoepithelial carcinoma. Diagnosis was further confirmed by positive immunohistochemical staining with calponin (CALP) and periodic acid-Schiff (PAS) for glycogen.
