title: [A case report of a solid and cystic tumor of the pancreas in a 33-year-old woman].
abstract: An unusual case of a solid and cystic tumor of the pancreas is presented. A 33-year-old woman with a 15-year history of an abdominal tumor underwent a pancreatectomy. The tumor was encapsulated by a thick connective tissue and exhibited two main patterns: solid sheets of relatively uniform small cells; and, a papillary proliferation with a central fibrovascular talk. The tumor cells had PAS and d-PAS reactive granules in the cytoplasm. Immunohistochemically, a positive reaction for alpha l-antitrypsin and a carcinoembryonic antigen, as well as a weekly positive reaction for a vasoactive intestinal polypeptide also were found in the cytoplasm. Our results lead us to suggest that an S-C tumor is likely to be a tumor of a acinar cell origin.
