1. Cystic dilatations of pancreatic ductules were recognized in 37 cases of the random selected 85 autopsy cases.
2. Cystic dilatations show tendency to appear in multiple locations in pancreas.
The small dilatations are round or oval shaped, the larger dilatations are tend to show irregular shapes.
3. The observed frequency of cystic dilatations showed a certain increase in proportion with the aging.
4. In cases of the subsistence of accessory pancreatic ducts, cystic dilatations are observed smaller in number.
5_Cystic dilatations are considered deeply concerning with the running pattern of the pancreatic ducts.
6. The diameter of main pancreatic duct is increased with the aging, both on X-ray films examination (at the largest diameter) and on histological sections.
7. Cystic dilatations has any relationship neither associated disease, nor pancreatic weight and sex differences.
8. Cystic dilatations of pancreatic ductules tend to appear just below the pancreatic surfaces.
That pancreatic tissue supposed to show a loss of tension, due to atrophy and dissapearance of pancreatic parenchyma and also due to the viscid mucus production and retention from the goblet cell metaplasia.
Frequently, ductal epithelial proliferations are seen in association with the goblet cell metaplasia, are also seen cases of hyperplasia of ductal epithelium.
Concerning etiological relationship of cystic dilatations, the author is considering these may due to the chronic pancreatitis.
