Intraductal Papilloma of the Buccal Mucosa Salivary Gland

Salivary gland papillomas are rare tumours arising from the ductal epithelium. Intraductal papillomas, the most rare of all ductal papillomas, have been reported to occur almost exclusively in the excretory ducts of the minor salivary glands. An intraductal papilloma of the left buccal mucosa in a 51-year-old man is reported. Histology of resected tumour revealed that the duct had dilated to form a thickwalled cyst that contained the papillary tumour with intracystic endoluminal proliferation. No signs of recurrence were evident 8 months after surgery.
