Sialolithiasis is a pathological condition characterized by the formation of one or more calculi in the salivary glands. It is the most common disease of the salivary glands after mumps. The calculi usually range in size from 1 mm to 10 mm. They have rarely been reported to be larger than 15 mm. We describe a patient with a large calculus of the submandibular gland measuring 40 mm by 9 mm managed completely in the emergency department and present a review of the current literature related to the management of giant calculi.
