[Case of sialolithiasis with severe fatty change of the submandibular salivary gland].

Abstract

We encountered a 57-year-old female with sialolithiasis associated with severe fatty change in the submandibular salivary gland. The submandibular salivary gland was removed under general anesthesia, and the postoperative course was uneventful. Histopathological changes observed in submandibular salivary glands with sialoliths are mainly inflammatory cell infiltration or connective tissue infiltration. On the other hand, increase in fat cells with age has been reported, but these age-related fatty changes are not severe. It was considered that the cause of the fatty change in this case was related to anoxia, which increased with long-term stasis of the duct system that was brought on by the development of the sialolith.
