Abstract
Intraductal papilloma arising in the major salivary gland is uncommon. We treated intraductal papilloma of the parotid gland in a 41-year-old man with a 3-week history of a painless mass in his right parotid gland. Radiologic imaging studies revealed a well-circumscribed solitary mass, 1 cm in diameter, at the posterior edge of the right parotid superficial lobe. Complete excision of the mass was performed under general anesthesia. Pathologically, the mass consisted mainly of a cystically dilated salivary duct filled with dark brown muddy components and a cluster of growing papillary cells, leading to the diagnosis of intraductal papilloma. The literature on intraductal papillomas of the major salivary glands is reviewed, with particular focus on preoperative diagnosis of this condition.
