34 year old female, FNA of parotidA. Benign salivary gland tissueB. Pleomorphic adenomaC. Warthin’s tumorD. Adenoid cystic carcinomaE. Acinic cell carcinomaSerous cells with granular cytoplasm

resembling normal acinic cell, but unlike the distinct “bunches of grapes” arrangement of benign acinic cells intermixed with ductal cells, this FNA shows only sheets of acinic cells.

multiple deep nuclear indentations. Apparently, this type of cell is only seen in peritoneal mesothelial cells.
