Sialadenitis with crystalloid formation. Fine needle aspiration cytodiagnosis of 15 cases.
OBJECTIVE
To assess the utility of fine needle aspiration cytology in the diagnosis of sialadenitis with crystalloid formation.


METHODS
In 15 cases, salivary gland masses were aspirated using a disposable, 20-mL syringe and 25-gauge needles, maintaining negative pressure. Smears routinely were air dried and stained by Diff-Quik (Dade Behring AG, Düdingen, Germany). Occasionally smears were fixed in alcohol and stained by the Papanicolaou method.


RESULTS
The smears showed large numbers of non-birefringent crystalloids of varying sizes and shapes. The crystalloids stained deep blue with Diff-Quik and bright orange with Papanicolaou stain. Multinucleated histiocytes, neutrophilic leukocytes and benign salivary gland parenchyma were found, also.


CONCLUSIONS
Fine needle aspiration cytology provides an accurate diagnosis of sialadenitis with crystalloids and is useful for avoiding unnecessary surgery.
