Submandibular duct sialolith of unusual size and shape.

An unusual sialoith within Wharton's duct was associated with an abscess of the submandibular space. Previously reported sialoiths of considerable size are reviewed, and etiology, symptomatology, and surgical removal are discussed. Emphasis is placed on the need for thorough examination of patients who have symptoms of sialoithiasis in an attempt to locate the sialolith before it assumes unusual dimensions.
