case_images: (a) FNA smears from parotid swelling depicted predominantly papillary pattern (MGG stain, x100). (b) Higher magnification (MGG stain, x200). (c) Lobulated tumor showing microcystic and papillary pattern (H and E, x100)

case_images: FNA smears were highly cellular and showed cells arranged predominantly as papillae, focal acini, and as singly scattered [Figure 1]. Histopathologic examination showed a partially encapsulated lobulated tumor composed of cells arranged predominantly in sheets with focal acinar, microcystic, and papillary pattern [Figure 1c and d].
case_images: Cytological smears showed focal acinar pattern of cells, with eccentric nucleus and abundant cytoplasm (a: MGG stain, x200). (b) Higher magnification (MGG stain, x400). (c) Acinar pattern in the tumor with cells showing abundant granular cytoplasm (H and E, x200)

case_images: The cells had eccentrically placed nuclei and abundant slate gray cytoplasm showing vacuolations and fine red granularity [Figure 2]. Tumor cells were large, round-to-polygonal, with abundant amphophilic granular cytoplasm and central round vesicular nucleus [Figure 2c].
