A case of intraductal papilloma arising from deep lobe of parotid gland

Abstract

We report a case of intraductal papilloma in the deep lobe of the parotid gland. An 81-year-old male complained about swelling of the left parotid gland. A CT scan showed a tumor about 2cm in diameter with homogeneous enhancement in the deep lobe of the parotid gland. We diagnosed it as a benign parotid tumor and performed left parotidectomy. Histological examination revealed intraductal papilloma. Intraductal papilloma is a rare benign tumor that occurs mainly in the minor salivary glands. To date, only 11 cases of intraductal papilloma arising from the parotid gland have been reported. The present case is the first report of intraductal papilloma of the parotid gland arising from the deep lobe.
