Fine needle aspiration and frozen section of salivary gland lesions.
This report examines the role of fine needle aspiration (FNA) and frozen section (FS) examination in the management of salivary gland lesions, and is based on a review of 58 cases. FNA specimens were first classified as nonneoplastic, or as benign or malignant neoplasms. Identification of specific morphologic type of neoplastic lesions was attempted. Overall accuracy for assigning cases was 86%. Specific accuracy (histologic type of neoplasms predicted by FNA) was 72%. No inflammatory lesion was incorrectly diagnosed as neoplasm. Eight patients with histologically documented neoplasm had aspirates classified as nonneoplastic because the sample obtained was not representative. These data indicate that FNA is a highly specific method for identifying benign and malignant neoplasms. Applications of salivary gland FNA include (1) identification of nonneoplastic lesions that may respond to nonsurgical management, (2) identification of neoplasms that represent lymph node metastases rather than primary lesions of the salivary gland, (3) preliminary identification of lymphomas, and (4) preliminary separation of benign and malignant neoplasms.
