Cytology smears of discordant case 2 showing foci of clusters with peripheral cells showing nuclear atypia (a), nuclear hyperchromasia and pleomorphism (b). Squamoid polygonal cells with granular cytoplasm (c) and anucleate squames (d). The presence of squamous cells is a potential pitfall as they can be a reactive population in Warthin tumour and a dominant population of metastasis from a well differentiated squamous cell carcinoma.
