Lithiasis of minor salivary glands: Current data

Sialolithiasis is the main pathology of major salivary glands. Sialolithiasis of minor salivary glands is, however, generally considered to be extremely rare. Lithiasis of accessory salivary glands apparently occurs more frequently than alleged and therefore should be included in differential diagnosis of tumors of the oral mucous membrane. The elementary lesion consists of a firm nodule located under the mucosal membrane on the upper lip or cheek. Nodules should be excised and examined by histopathology.
