Sialolithiasis is common in major salivary glands and ducts, but sialolithiasis of minor salivary glands seems to be rather rare as judged by the small number of publications on this subject. A case of sialolithiasis of minor salivary glands in the right upper lip of a 24-year-old woman is presented. The purpose of this study is to review the information presented in the 10 previously reported cases of minor salivary gland lithiasis in Japan and to add the information gained from this case.
