Epithelial-myoepithelial carcinoma--review of clinicopathological and immunohistochemical features.

INTRODUCTION Epithelial-myoepithelial carcinoma is a low-grade malignant salivary gland neoplasm with a biphasic cell population that encompasses around 1% of all salivary neoplasms. METHOD We present different cases of epithelial-myoepithelial carcinoma, with special emphasis on histopathology, differential diagnosis, relevant prognostic factors and follow-up. RESULT This study included 8 patients who were diagnosed with epithelial-myoepithelial carcinoma and treated surgically including a follow-up period of at least 19 months. CONCLUSION Clinical and histopathological characteristics of these rare tumors are extremely valuable for accurate diagnosis and further therapy planning.
