Oncycytoma is a tumor which is abundunt with granular and eosinophilic cytoplasm and mitochondria. It can be found in various organs such as the kidney, thyroid gland, pancreas, and breast. Salivary gland is reported to be involved with oncocytoma in less than 1% among the salivary gland tumors. A 65-year-old female visited presenting with recurrent lump of the left parotid gland. She had been diagnosed with oncocytoma after left superficial parotidectomy 8 years ago. Physical examination revealed multiple painless tumors in the left parotid gland. Ultrasound and computed tomography showed multiple mass in the left parotid gland. The patient had a revision parotidectomy. Pathology confirmed an oncocytoma and nodular oncocytic hyperplasia. We report a rare case of recurrent oncocytoma and nodular oncocytic hyperplasia from the parotid gland and report the case with related literature. (J Clinical Otolaryngol 2021;32:302-307)
