Figure 2: (a-c) A case of xanthogranulomatous cholecystitis which on fine-needle aspiration cytology was kept in diagnostic Category 3 showed cellular smears with cells having nuclei with minimal anisonucleosis, bland chromatin, inconspicuous nucleoli, and foamy cytoplasm. (May Grunwald Giemsa, ×10, ×40). (d-f) fine-needle aspiration cytology of the gallbladder led to false-positive diagnosis of Category 4 in a case which later histopathologically proved to be adenomatous hyperplasia (f). The smears were cellular, showed moderate pleomorphism but close examination of nuclei showed mostly uniform chromatin (May Grunwald Giemsa, ×40; H and E, ×20)
