We performed distal pancreatectomy (Fig. 2).
Pathological findings. a Pathological examination of the resected specimens revealed dilatation of main and branched pancreatic duct involving papillary proliferation (bar, 2,000 mum). b The ducts were filled with mucin (bar, 2,000 mum). c The tumor cells invaded not only in these ducts but also the pancreatic parenchyma (bar, 400 mum).
