Multifocal nodular oncocytic hyperplasia in parotid gland:a case report
BACKGROUND: Multifocal nodular oncocytic hyperplasia (MNOH) is a rare lesionof the parotid gland. Fine needle aspiration cytology (FNAC) in MNOH has not been describedpreviously to the best of our knowledge. CASE: A 55-year-old woman presented with a lump at the leftangle of her mouth for 2 months. Local examination revealed a hard, nontender parotid mass. FNACrevealed clusters as well as discretely lying oncocytic cells. cells at places showed moderatenuclear pleomorphism. The features were consistent with a diagnosis of oncocytic neoplasm neoplasm;however, because of pleomorphism, a suspicion of carcinoma was offered. The patient underwentsuperficial parotidectomy, and histopathology examination revealed it to be multifocal nodularoncocytic hyperplasia. CONCLUSION: MNOH is a rare nonneoplastic salivary gland lesion and should beconsidered in the differential diagnosis of oncocytic neoplasm on FNAC.
