Spontaneous Discharged Submandibular Gland Duct Sialolith: Α Rare Case Report

Sialolithiasis is the most common pathology of the salivary gland characterized by the development of salivary stones, known as calculi or sialoliths. Sialoliths commonly measure between 5 and 10 mm in size, and all stones over 10 mm can be reported as sialoliths of unusual size. Sialolith of more than 15 mm is defined as giant sialolith and is extremely rare. Most salivary sialolith occurs in the submandibular gland duct, especially located in the distal third of the duct. The main signs and symptoms are local pain and swelling. The treatment option to remove the sialolith is according to its size and location. For giant sialolith, surgical removal with or without the gland excision needs to be considered. Here, we report a case of giant submandibular gland sialolith of 35 mm in greatest dimension. And this is the first reported case of giant salivary gland duct sialolith discharged spontaneously.
