The accuracy of salivary cytology is high for the diagnosis of the most common salivary gland tumors such as pleomorphic adenoma and Warthin tumor, but the specificity for subtyping a particular neoplasm shows a wide range (48 to 94 percent) depending on tumor type. We had 15 patients with a final histopathology showing a cyst.

Tumor seeding is an extremely rare occurrence. Pleomorphic adenoma is a common benign salivary gland neoplasm characterised by neoplastic proliferation of parenchymatous glandular cells along with myoepithelial components, having a malignant potentiality. Preoperative management generally includes clinical evaluation, collection of a pathological sample, most often through fine-needle aspiration cytology (FNAC), and imaging. interpretative difficulties on fine-needle aspiration (FNA) diagnosis. The normal cells observed in all adenolymphomas could be interpreted as outgrowing stroma cells. In a minority of benign neoplasms (namely, pleomorphic adenoma [PA] and Warthin tumor), FNA can provide a specific FNA diagnosis, which allows for the option of: 1) surgical intervention in a subset of patients or 2) management of the patient by clinical follow-up and imaging, depending on health status and patient wishes.
