Very interesting case. Unfortunately, the quality of the slide is suboptimal. If all the slides look like this, it is definitely a neoplasm. You need to get the history of what exactly is her previous malignancy, if possible, compare the morphology of that. It is very important to differentiate primary salivary gland neoplasm vs. metastasis, since the treatment will be very different.
My approach to salivary gland FNA is that if a tumor is not neatly fit into any known subtype of salivary gland neoplasm, don't force yourself into one specific diagnosis, if it is primary, ask the surgon to take it out. Salivary gland FNA can be very difficult and have a lot of overlapping features. Cytologists are usually good at differentiating neoplasm vs. non-neoplastic process and low-grade vs. high-grade maliganant neoplasm, but have problems with a specific diagnosis.
Back to this case, I not only see some papillary structure but also see some glandular or tubular formation, I don't see a distinct myoepithelial component. I favor this is an epithelial neoplasm, maybe just adenocarcinoma.
