N2 - OBJECTIVE: To review the fine needle aspiration (FNA) findings in 151 patients who presented with salivary gland (both major and minor) enlargement from January 1991 to December 1995 in order to determine its sensitivity and specificity and tostudy the various pitfalls. STUDY DESIGN: The study group consisted of 77 males and 74 females, 16-98 years old (average 55). One hundred twenty-five aspirates (83%) were from the parotid gland, 23 (15%) from the submandibular gland and 3 (2%) from thesoft palate. One hundred thirtyseven cases (91%) were adequate for diagnosis. There were 89 (59%) aspirations done by cytopathologists, 100% of which were diagnostic, and 62 (41%) done by clinicians, 48 (77%) of which were diagnostic. Sixtyeight (45%) cases had histologic confirmation. There were 104 (75.9%) benign, 20 (14.6%) malignant and 13 (9.5%) atypical cytologic diagnoses. RESULTS: Using histology as the “gold standard,” the sensitivity of FNA cytology was 91%, with a specificity of 96%. A number of problems were encountered in interpretingsome cases, not only in differentiating benign from malignant ones but also in the specific classification of these neoplasms.Problems encountered involved differentiating hematopoietic from nonhematopoietic lesions and interpretation of spindle cell neoplasms, acinic cell carcinoma, mucoepidermoid carcinoma, adenoid cystic carcinoma, lymphoproliferative disorders, postirradiation changes, sialadenitis and atypia in pleomorphic adenoma. CONCLUSION: FNA biopsy of the salivary gland is a sensitive andspecific diagnostic tool at our institution. Particular attention to subtle morphologic changes may aid in avoiding pitfalls and arriving at the right diagnosis.
