Pancreatic carcinoma accompanied by XXXX : report of two cases.

@entity1 @entity32 @entity788 @entity5409 @entity5 @entity984 @entity189 @entity615 @entity1358 @entity9007
Two cases of pancreatic @entity5 accompanied by @entity9007 are reported. Case 1 was a 60-year-old @entity1 who was admitted to our hospital complaining of left lower abdominal discomfort. A @entity5409 , about 3 cm in diameter, was found in the pancreatic tail by ultrasonography (US) and computed tomography (CT). No signs of chronic @entity788 were found. At operation, an elastic, hard, white @entity5 , about 1 cm in diameter, was felt adjacent to the @entity5409 on the duodenal side. Histologically, this @entity5 was a @entity1358 with an adjacent @entity9007 upstream of the pancreas. Case 2 was a 57-year-old @entity1 who complained of @entity615 and loss of body weight. US and CT examination revealed a @entity5409 , 11 x 7 cm in size, in the tail of the pancreas. Histological examination of the resected specimen revealed both a @entity1358 , 3 cm in size, in the body of the pancreas and a @entity9007 , 9 cm in size. Pseudocysts accompanying @entity189 are thought to develop from obstruction of the pancreatic duct by the @entity189 , followed by intraductal high pressure and disruption of ductules upstream of the pancreas. Thus, we should pay careful attention to @entity9007 , especially when signs of @entity32 cannot be found, to help identify @entity1358 in the early stage. Further detailed examinations of the cyst fluid or pancreatic juice, such as cytology, @entity5 marker determinations, or establishment of @entity984 codon 12 mutation, are needed.
