Correlations between p53 gene mutations and histologic characteristics of pancreatic ductal carcinoma.

Objective: With the aim of improving early detection of pancreatic carcinoma, we attempted to make correlations among positive immunohistochemical detection of p53 expression, mutations in the p53 gene, and detailed histologic features of pancreatic carcinoma.

Methods: Seven cases of invasive pancreatic ductal carcinoma demonstrating p53 overexpression were analyzed. Serial 4- and 20-microm sections from paraffin blocks were used for immunodetection of p53 protein and microdissection, respectively.

Acute pancreatitis from mumps re-infection in adulthood. A case report.

Context: Acute pancreatitis is a complication of mumps which mainly affects children who then usually acquire permanent immunity. We present the case of a woman with acute pancreatitis caused by mumps re-infection in adulthood.

Case Report: A 34-year-old woman developed mild acute pancreatitis caused by re-infection with mumps, as confirmed serologically by enzyme-linked immunosorbent assays mumps-specific IgM and IgG.

Pseudomyxoma peritonei occurring after an uneventful 23 years interval from appendectomy.

A 77-year-old male was admitted to our hospital for a bulky abdominal mass. He had a history of appendectomy under the diagnosis of appendiceal rupture 23 years previously. He also had received a radical lung resection for an early lung cancer 2 years earlier in another hospital.

Solid pseudopapillary tumor as a possible cause of acute pancreatitis.

Context: Acute pancreatitis is not commonly seen in the first presentation of pancreatic neoplasms. Solid pseudopapillary tumor as a cause of acute pancreatitis has not yet been reported. This is the first report of acute pancreatitis resulting from solid pseudopapillary tumor.
