Ganglioneuroblastoma arising within a retroperitoneal mature cystic teratoma.

We discuss an extremely rare case of ganglioneuroblastoma arising within a retroperitoneal mature cystic teratoma. Radiological examinations showed a cystic tumor sandwiched between the pancreas and left kidney. Surgery was scheduled because the tumor seemed to have originated from the pancreas.

Metachronous pancreatic acinar cell carcinoma discovered in early stage during follow-up of breast cancer: report of a case.

Primary sclerosing cholangitis associated with autoimmune pancreatitis.

We present 2 cases of primary sclerosing cholangitis complicated with autoimmune pancreatitis with narrowing of the pancreatic duct. In both cases, endoscopic retrograde cholangiography showed the characteristic findings of primary sclerosing cholangitis. In addition, positivity for autoantibody, hypergamma-globulinemia and narrowing of the pancreatic duct shown on endoscopic retrograde pancreatography were noticed in both.
