Salivary Gland Fine-Needle Aspiration: The Current and Future Landscape

Fine-needle aspiration represents a valid tool for the diagnosis/management of salivary gland lesions. The past years assessed the lack of uniform diagnostic reports for salivary cytopathology leading to interpretative issues. In 2015, an international group of cytopathologists developed an evidence-based tiered classification system for reporting salivary gland fine-needle aspiration (FNA) specimens, the "Milan System for Reporting Salivary Gland Cytopathology" (MSRSGC). The present landscape of salivary cytology is represented by the growing adoption of the MSRSGC and the assessment of its diagnostic role. The future landscape is characterized by the increasing role of ancillary techniques for diagnostic and prognostic purposes.
