Core Tip

Core tip: Epithelial-mesenchymal transition (EMT) has been associated with cancer invasion and metastasis as epithelial cells acquire the ability to migrate and invade; these observations have been related to the generation of a stem cell population within the neoplasm. We report here a resected case of multiple carcinosarcomas with adeno-carcinomatous components that may have developed secondary to EMT. Detailed elucidation of the relationship between the pathogenesis of carcinosarcoma and EMT are among the future challenges in this field.
