A case of intraductal papilloma arising in the sublingual gland

Abstract

Intraductal papilloma is a luminal papillary proliferation of duct epithelium that arises from a segment of the interlobular or excretory duct and causes unicystic dilatation, and is very rare. A review of the Japanese literature reveals no reports of intraductal papilloma arising in the sublingual gland.
We report a case of intraductal papilloma arising in the sublingual gland that was diagnosed as submandibular sialoadenitis.
A 38-year-old woman visited our hospital with the chief complaint of right submandibular swelling. We detected a mass in the right sublingual gland that caused obstruction of the submandibular duct. MR imaging suggested that the round mass had a clear and smooth margin in the sublingual gland.
The tumor was enucleated under local anesthesia. The excised specimen was histologically diagnosed as intraductal papilloma of the sublingual gland.
