Abstract
Oncocytoma is an uncommon, benign salivary neoplasm composed of mitochondria-rich oncocytes. It usually occurs in the parotid gland, seldom in submandibular gland and generally account for less than 1% of all salivary gland tumors. They are typically tumors of older adults with a slight female predominance. Clinical and radiological features of the parotid oncocytoma are not different from those of the others parotid benign tumors. Clinical diagnosis for an oncocytoma is challenging for its similar features to other benign tumours. Histopathological diagnosis is reliable with histochemical and electron microscopic conformation of the oncocytes. Surgery is the best treatment option. We report a rare presentation of oncocytoma of the parotid gland in a young adolescent female who presented with progressive swelling in the left parotid region.
