Approach to Salivary Gland Cytology

Salivary gland cytology is a complex area, with some inherent limitations and challenges. This chapter briefly outlines the Milan System for Reporting Salivary Gland Cytology and provides an outline of the common and important entities encountered in salivary gland FNAs. It highlights the neoplasms that cytology can and cannot diagnose.
The morphologic discussion centres around four common cell types seen in salivary gland neoplasms—basaloid, oncocytic, clear cell and spindle. The spectrum of differentials will be presented, and discussion will also occur in tandem with specific stromal appearances.
Several particularly challenging areas are also elaborated on cystic lesions, basaloid lesions and others. Finally, specific pitfalls in salivary gland cytology are presented, along with practical tips and clues.
