Multifocal nodular oncocytic hyperplasia clear cell variant: a rare case report of salivary gland lesion

Nodular oncocytic hyperplasia




Nodular oncocytic hyperplasia, oncocytosis, salivary gland


Nodular oncocytic hyperplasia are rare nonneoplastic lesions of the salivary glands. Histopathologically, it is characterized by multiple unencapsulated nodular proliferations. It can be confused with tumors in the differential diagnosis both cytopathologically and histopathologically. Differential diagnosis should be made with metastatic tumors and clear cell salivary gland tumors, especially if clear cells predominate. In this case, we presented the cytological, histopathological and immunohistochemical findings of clear cell dominant nodular oncocytic hyperplasia located in the deep lobe of the parotid unilaterally in a rare 72-years-old male patient.
