Abstract: | OBJECTIVE: To assess the utility of fine needle aspiration cytology in the diagnosis of sialadenitis with crystalloid formation. STUDY DESIGN: 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. CONCLUSION: Fine needle aspiration cytology provides an accurate diagnosis of sialadenitis with crystalloids and is useful for avoiding unnecessary surgery. |
