title: Pancreatic carcinoma with duct, endocrine, and acinar differentiation. A histologic, immunocytochemical, and ultrastructural study.
abstract: An unusual case of pancreatic carcinoma with components of poorly differentiated adenocarcinoma and islet cell tumor is reported. Histologic, immunocytochemical, and ultrastructural evidence of ductal, endocrine, and exocrine (acinar) differentiation is presented. The implications with regard to endocrine cell differentiation and the histogenesis of pancreatic neoplasms are discussed.
