Type of Preparation:
Direct Smear
Magnification:
Intermediate Power
Clinical History:
64-year old male with parotid mass
Interpretation:
Fig. 3.6a Non-Neoplastic: Chronic sialadenitis
Cytomorphologic Criteria:
• Hypocellular sample
• Small groups of ductal cells, may be basaloid or metaplastic
• Absent or scant acinar cells
• Chronic inflammation (including lymphocytes and plasma cells)
• Fibrotic stromal fragments
Explanatory Notes:
The combination of a hypocellular aspirate with absent acinar cells, small cohesive
ductal groups, and mild chronic inflammation is characteristic of chronic sialadenitis, but clinical and radiologic correlations are needed to exclude a non-representative FNA sample.
