Abstract
We experienced a rare case of cholecystitis, cholecystolithiasis and acute pancreatitis, revealing heterotopic pancreatic tissue in the cystic duct by the postoperative pathohistological examination. This paper presents the case with a review of the literature.
A 52-year-old woman was seen at the hospital because of an upper abdominal pain. Elevated liver function levels and markedly high amylase in urine and blood were noted by biochemical examinations. Abdominal ultrasonography and CT scan revealed cholecystolithiasis and hypertrophy of the cystic wall, but no marked change was noted on images of the pancreas. Being diagnosed as cholecystitis, cholecystolithiasis, and acute pancreatitis, an operation was carried out when the symptoms ameliorated. The excised gallbladder showed hypertrophy of the wall, with multiple small black stones inside, Further, there existd two cholesterol polyps. Pathohistological examination of the excised specimen reveaeld heterotopic pancreatic tissue of the Heinrich II type consisting of acini and excretory ducts about 1 mm in size located from the lamina propia to tonica muscularis in the cystic duct.
