The authors report a case of cystic neoplasm of the pancreas treated b
y cystojejunostomy two years and half earlier, On that occasion, a fal
se diagnosis of pancreatic pseudocyst had been suggested. Cystic neopl
asm of the pancreas has a far better prognosis than adenocarcinoma, Ho
wever, early detection is difficult and erroneous initial diagnosis ma
y lead to delayed treatment and poor long-term results. In our case, t
hough surgical treatment was aggressive and apparently radical, early
recurrence of neoplasm was observed. Only early accurate diagnosis of
pancreatic cystadenocarcinoma might improve the results of surgical tr
eatment.
