Sialolithiasis: An Unusually Large Salivary Stone

Sialolithiasis is characterized by obstruction of a salivary gland or its duct due to the formation of calcareous concretions, leading to recurrent painful swelling of the involved gland. It is aggravated while eating. Submandibular gland is the most commonly affected gland. The size of the sialolith may range from 1 to 10 mm. Sometimes, the formation of sialo-oral or sialo-cutaneous fistula may promote the growth of the sialolith to a giant size of 15 to 20 mm. Giant sialolith of size greater than 20 mm is sparse in the literature. The purpose of this presentation is to report a case of an unusually large sialolith measuring 28 mm located in the left submandibular salivary gland of a 29-year-old male patient.
