FNAC salivary gland

Sialosis

A non-inflammatory, often bilateral, chronic, painless, diffuse swelling of the salivary glands, particularly of the parotid caused by hypertrophy of the acinar cells. It is associated with hormonal, nutritional or neurogenic disorders and with systemic diseases such as diabetes and misuse of alcohol.
Cytologically, numerous benign acinar cells are present and ductal cells are sparse. Care must be taken not to confuse this with weIl—differentiated acinic cell carcinoma.

Lipomatosis

A diffuse excess of interstitial fat, which may occur in obesity and diabetes and occasionally presents as a diffuse swelling. Fatty replacement of atrophic parenchyma, sialollpoma, periparotid lipomata, and sialometaplasia in pleornorphic adenoma are other causes of fat cells in an aspirates.
