“Atypical” salivary gland fine needle aspiration: Risk of malignancy and interinstitutional variability

Abstract

More than half of the subset of "atypical" salivary gland FNAs with histological resection turned out to be malignant tumors; another one-fourth were benign neoplasms. Further, the highly variable ROMs of the "atypical" category amongst different institutions likely reflect the variable practices at each individual institution.
