Albumin expression distinguishes bile duct adenomas from metastatic adenocarcinoma

Aims Bile duct adenomas may be difficult to distinguish from metastatic carcinomas, particularly well‐differentiated pancreatic ductal adenocarcinoma. Prior studies have evaluated the utility of various immunohistochemical markers, although these markers are notable for low sensitivity and/or specificity. The aim of this study was to investigate the utility of albumin and BRAFV 600E expression in distinguishing between metastatic pancreatic...
