Frequency and Characterization of Benign Lesions in Pancreatic Specimens of Patients Operated for the Suspicion of Pancreatic Cancer

摘要: Context A final diagnosis of benign lesions is reported in up to 21% patients who underwent duodenocephalopancreatectomy for neoplasia, whereas no data have yet been published resection the body-tail. Objective To investigate frequency and characterize mimicking a neoplasia head body-tail pancreas. Methods We retrospectively reviewed all pancreatic specimens collected from 2005 2011 database Institute Pathology Mainz. Patients with excluding malignancy were analyzed by histological, clinical imaging findings. Results Three-hundreds 73 identified. disease was observed 33 (8.8%), 25 out 298 (8.4%) resections 8 75 (10.7%) Among them we found paraduodenal pancreatitis (PP) 13 cases (39.4%), autoimmune (AIP) 11 (33.3%), chronic (CP) 6 (18.2%) accessory spleen 3 (9.1%). In pancreas most frequent PP AIP, CP. more likely be males, younger, smokers drinkers, longer lasting pain. Lower serum levels CA 19-9 lower jaundice frequently this group. Pancreatic calcifications associated larger dilation common bile duct malignant lesions. AIP different radiological profiles. Conclusion Benign are same or pancreas, while type different.
