title: Induction of a mixed ductal-squamous-islet cell carcinoma in a rat treated with a tobacco-specific carcinogen.
abstract: Treatment of rats with tobacco-specific nitrosamines resulted in the induction of pancreatic acinar cell and ductal cell neoplasms. One of these tumors had a mixed ductal-squamous-islet cell components, the electron microscopic and immunohistochemical patterns of which are described. This is the first report of such a pancreatic mixed cell neoplasm.
