A cyto-and histopathological study in a case of chronic pancreatitis with atypical cells in the bile

Abstract

A case of 49 year-old male with chronic pancreatitis was reported. His chief complaints at admission were right epigastralgia and jaundice. Percutaneous transhepatic cholangiography (PTC) showed a stricture of the distal common bile duct with dilatation of the proximal portion and pooling in the pancreatic head, suggestive of cancer of the pancreatic head. Cytological study in the bile from PTC-drainage also showed atypical cells diagnosed as Positive. Laparotomy was performed and a swollen pancreas in head was found. So, pancreatectomy was done. However, histopathological study showed no cancer, but confirmed chronic relapsing pancreatitis with benign stricture of the distal common bile duct and inflammation in the dilated proximal bile duct.
Therefore, we had erroneously considered the abnormal regenerating epithelia in the bile duct to be the malignant cells.
