title: Sialolithiasis of minor salivary glands: a clinical and histopathological study.
abstract: Sialolithiasis is one of the most common disorders of particular major salivary glands. It is caused by sialolith within the ducts or parenchyma of particularly major salivary glands. Although sialolithasis is not uncommon, it often is clinically misdiagnosed when minor salivary glands are affected. This article describes the clinical and microscopic findings of nine cases of sialolithiasis of minor salivary glands. The lesions frequently appeared as single and asymptomatic nodules in middle-aged patients. Only three sites were affected: four lesions were found in the upper lip, three in the buccal mucosa, and two in the lower lip. The most common clinical hypotheses for diagnosis were mucocele, sialoadenitis, and benign salivary gland tumor. Sialolithiasis of minor salivary glands was misdiagnosed frequently. It should be considered as a possible diagnosis when swelling of the oral tissues is observed.
