    The silver positive cells of the exocrine pancreas and primary pancreatic cancers were studied with the Grimelius silver stain and the Fontana-Masson technique. In the pancreas, cells containing black granules with the Grimelius method, which at the same time react negative to Fontana-Masson, are considered argyrophil. These cells were present in the basal portion of some of the acinar tissue and in the ductal epithelia, as well as in the A cells of islets. The incidence and distribution of these argyrophil cells were also studied in a variety of ductal lesions. In the so-called ductal proliferation numerous numbers of positive cells were found. Argyrophil cells were frequently situated in the basal portion of ductal squamous cell metaplasia. In goblet cell metaplasia the numbers were few, and less than in normal ducts. We concluded that the distribution and incidence of argyrophil cells in the ductal epithelia is related to chronic pancreatitis, and in particular to regenerative processes. The incidence of argyrophil cells in primary pancreatic cancer, excluding islets cell origin, was 18 per 41 cases (43.4%). We considered them pancreatic cancer with argyrophil cells.
