Sialolithiasis is the most common disorder associatd with major salivary glands. It may form in any salivary glands or ducts, but is reported to occur more often in the submandibular gland than in the parotid or sublingual gland. Although the pathogenesis is not perfectly revealed, there appear to be several factors that predispose the submandibular gland duct to be a common site of sialolithiasis. Sialolithiasis occurs as a consequence of the precipitation of calcium salts around a central nidus of desquamated epithelial cells, inflammatory cells, mucoid gels or foreign body. However, it is not a common thing that foreign body entered into the salivary duct through duct orifice may act as the initiating factor. We have recently experienced a case in a 52-year-old female, in which sialolithiasis seems to have formed due to a a foreign body, a fish bone, in the right submandibular gland duct.
