Salivary duct carcinoma is rare high grade adenocarcinoma, arising from larger excretory duct in major salivary gland, resembling the ductal carcinoma of the breast histologically. We report a case of salivary duct carcinoma of left parotid gland in which fine needle aspiration cytology was performed. Cytologic examination revealed 1) moderate cellularity, 2) flat sheets or three dimensional, tightly cohesive clusters on the necrotic background, 3) sometimes cribriform or papillary configuration, 4) polygonal or cuboidal cells with moderate anisonucleosis with abundant, granular and eosinophilic cytoplasm, 5) round to oval nuclei with irregular chromatin clumps, and 6) 1 or 2 inconspicuous nucleoli. Histologically, the tumor is mainly composed of cribriform intraductal component with central comedonecrosis, and small foci of infiltrating component including well differentiated ductal structures or irregular sheets in a desmoplastic stroma.
