[Solid cystic acinar cell tumor of the pancreas. Immunohistologic studies of histogenesis].
A case of a very rare solid and cystic tumor of the pancreas in a 25-year-old woman was examined by immunohistochemical methods, e.g. antiglucagon, antisomatostatin, antivip etc. The stainings by the PAP- or biotin-avidin-method were negative and also those with S-100 protein and especially with chromogranin. A tumor of the endocrine system was therefore excluded. Some areas of the tumor showed positive staining with alpha-1-antitrypsin as is known in acinar cell carcinoma. The classification of the neoplasm as an acinar adenoma of the pancreas seems to be well established, mainly because several authors electronmicroscopically demonstrated structures resembling acini and zymogen granules.
