Sialolithiasis of an accessory parotid gland: an unusual case.

We report a rare case of sialolithiasis of an accessory parotid gland, which was located anteromedial to the masseter muscle and isolated from the main parotid gland. The calculus developed from this accessory gland, and the main gland was free of lithiasis and inflammation. To our knowledge, there is no reported case of 14 stones in an accessory parotid salivary gland. The calculus was removed through a standard incision without injury to the facial nerve or a salivary fistula.
