Clinicopathological characteristics of primary pancreatic lymphoma: report of two cases.

Primary pancreatic lymphoma (PPL), originating from the pancreatic parenchyma, is a rare type of lymphoma. The symptoms and radiographic findings of PPL are quite similar to pancreatic adenocarcinoma (PAC), and thus it is often misdiagnosed. In this study, we described the clinical features, radiographic findings, histological and immunohistochemical analysis, molecular detection and clinical treatment of two cases of PPL, aiming to distinguish PPL from PAC.
