A RARE CASE OF LARGE SALIVARY STONE WITH CALCULOSIS SIALADENITI REMINDING TOPINAMBUR TUBES

Abstract

Calculous sialadenitis (salivary stone disease) is one of the most common diseases and ranges from 30 to 78% in the structure of the pathology of the salivary glands. Stones, as a rule, are localized in the submandibular gland and submandibular duct (90-95%). This is a polyetiological disease. The basis of stone formation, along with the known links of pathogenesis (disturbances in mineral metabolism, impaired secretory function, etc.), is the presence of congenital changes in the salivary glands by the type of local expansion (ectasia) of ducts of various calibers and the peculiarity of the topography of the main duct in the form of a broken line with sharp bends, in which the calculus is formed. The shape of the stones is different. The stones located in the gland are rounded, often have an uneven surface. Calculi localized in the duct of the salivary gland, in most cases, have an oblong shape. The size of the calculi ranges from 1 mm to 1.0 cm. Large salivary stones larger than 1.5 cm are very rare, giant stones larger than 3 cm are extremely rare. Analysis of the literature found a description of only 16 clinical cases of salivary stone disease, when the size of the salivary stone was more than 3.5 cm.
