Submandibular giant sialoliths: report of two cases and review of the literature.

Sialolithiasis is one of the most common diseases of the salivary gland, but giant sialoliths have been reported in the literature infrequently. The submandibular gland and its duct appear to be the sites most susceptible to this disease. We report 2 cases of giant sialoliths occurring solely in the submandibular duct.
