    ..Our current study confirms previous reports that both encapsulated PTC-CV and encapsulated PTC-FV are indolent tumors and are associated with very low mortality. ..

    ..We expect that these rigid morphologic criteria will potentially reduce interobserver variability and enhance consistency in the diagnosis and staging of thyroid carcinoma. ..

    ..All cases of MEC were positive for thyroglobulin, whereas all cases of SMECE were negative. The immunohistochemical findings suggest that both MEC and SMECE have different histogenesis. ..

    ..We conclude that ultrasound-guided FNA combined with on-site evaluation and different cytologic preparations can significantly improve the diagnostic accuracy of thyroid FNA specimens. ..
