Abstract
- Parotid oncocytoma is a benign salivary gland neoplasm that represent approximately 1% of all salivary gland tumors. Histopathologically, this condition consists of oncocytes, which are polygonal cells with abundant granular eosinophilic cytoplasm, ultrastructually showing an increased number of mitochondria. We herein report a typical case of oncocytoma of the parotid gland in a 73-year-old woman who presented a 2X2 cm, reddish firm nodule on the right postauricular area for 3 years.
