title: Salivary duct cyst: its frequency in a certain Japanese population group (Tohoku districts), with special reference to adenomatous proliferation of the epithelial lining.
abstract: It is reported in the European and American literature that salivary duct cysts constitute about 10% of all cysts of the salivary glands, although they appear to be rare in Japan. Between 1975 and 1999, only 3 (0.5%) of 586 salivary gland cysts were diagnosed as salivary duct cysts at the Division of Clinical Pathology, Iwate Medical University Hospital. Histologically, two cases appeared as a unilocular lesion lined by double- and multi-layered epithelium. The other case showed marked, intraluminar and intramural adenomatous proliferation of the epithelial lining, suggesting that the lesion was a benign tumor. A review of the literature yielded only two cases of tumors arising in pre-existing salivary duct cysts.
