A Patient with Chronic Hepatitis C and a Pancreatic Mass in Endoscopic Ultrasound

We report a rare case of pancreas tumor (lymphoma) in a patient with a history of chronic hepatitis C virus (HCV) infection without treatment, with a high viral load (20,199,805 IU/ml). He presented with abdominal pain, jaundice, weight loss and sweating. Computed tomography showed a hypodense mass located in the head of the pancreas, and immunohistochemistry of a specimen obtained by endoscopic ultrasound-guided fine needle aspiration revealed non-Hodgkin’s lymphoma of the pancreas, B cell type. An association of HCV infection with pancreatic lymphoma has only been reported rarely in the literature and its clinical significance is uncertain.
