TY - JOUR A2 - Ribera, Josep M. AU - Alzerwi, Nasser A. N. PY - 2020 DA - 2020/02/26 TI - Primary Pancreatic Lymphoma Masquerading as Carcinoma SP - 5160545 VL - 2020 AB - Adenocarcinoma is the most common primary pancreatic neoplasm type, followed by secondary pancreatic lymphoma and primary pancreatic lymphoma (PPL). PPL is associated with peripancreatic lymphadenopathy and usually presents as a homogenous mass with extrapancreatic invasion into surrounding structures. However, localized involvement of the distal pancreas is uncommon, and diffuse involvement of the pancreas is even rarer. Herein, we present the case of a 53-year-old woman with PPL of the uncinate process with biliary obstruction mimicking pancreatic adenocarcinoma, successfully diagnosed nonoperatively. Abdominal computed tomography showed an ill-defined uncinate process mass, hypodense with mild enhancement ( 3.9 × 3.4 × 3.5 厘米 ），渗透十二指肠的第二和第三部分。活检显示NHL没有腺癌的证据。PPL被诊断出来。她接受了用rituximab的剁（环磷酰胺，多柔比星，长春猴和泼尼松）方案的化疗，她耐受，没有临床或放射学证据的临床或放射性证据。SN - 2090-6706 UR - HTTPS://Doi.org/10.1155/2020/5165/2020/5160545 Do - 10.1155 / 2020/5160545 JF - 肿瘤医学案例报告PB - Hindawi KW - ER -
