Abstract

The Suspicious for Malignancy (SM) category is a traditional diagnostic category used in nearly all cytology reporting systems, and, as such, its characteristics are well known to practicing cytologists. The purpose of separating the SM from the Malignant category is to preserve the high positive predictive value (PPV) of an FNA classified as malignant while at the same time offering a diagnostic option with a relatively high ROM for those FNAs where the cytomorphologic criteria fall short in quantity and/or quality for a malignant interpretation. In the second edition of the Milan System, the ROM for the SM category is 83%. With the growing availability of immunohistochemical and molecular markers for salivary gland tumors, a subset of FNAs classified as SM may benefit from the application of ancillary testing to yield a more specific interpretation.
