Benign lymphoepithelial lesions (BLLs) usually affect the parotid glands, resulting in their asymmetrical enlargement. The condition can be associated with Sjogren's syndrome (SS), which in turn may predispose the affected patient to the development of malignant lymphoma. BLLs arising in the intraoral minor salivary glands are rare; such a lesion should prompt the work-up for SS. In some instances, a BLL of a minor salivary gland could represent the initial stage of a mucosa-associated lymphoid tissue (MALT) lymphoma. A case of BLL arising in the palatal minor salivary glands is reported here. The importance of an appropriate diagnostic work-up is emphasized and the relationship of BLL with SS is reinforced.
