Representative examples in each diagnostic category of the MSRSGC

Caption

(a) Non-diagnostic: FNA of a right parotid gland “lesion” showed only scant salivary gland parenchymal cells (Papanicolaou stain). (b) Non-neoplastic: FNA of a right parotid gland showed abundant neutrophils and histiocytes, consistent with abscess (Diff-quik stain). (c) AUS: FNA of a right parotid gland lesion showed single large atypical cells in the background of lymphoid tissue (Papanicolaou stain). Follow-up surgical resection revealed low-grade Non-Hodgkin B-cell lymphoma. (d) Neoplastic-benign: Classic cytomorphologic features of PA showed by Papanicolaou stain. (e) SUMP: A cellular specimen with basaloid appearing cells diagnosed as SUMP (Diff-Quik stain). Follow-up surgical specimen revealed basal cell adenoma. (f) SM: Clusters of epithelial cells including scattered mucin-filled cells, suspicious for neoplasm. Overall cellularity was low. Follow-up surgical specimen showed low-grade mucoepidermoid carcinoma (Papanicolaou stain).
