Abstract
Primary B-cell lymphoma of the liver is an extremely rare tumor. The higher incidence of hepatocellular carcinoma in hepatitis C is well known, but the relationship with lymphoma is unclear. An increased incidence has been reported in patients with chronic hepatitis C. Hepatitis C virus is known to be a lymphotropic virus. Mixed cryoglobulinemia, which is a benign lymphoproliferative disorder, has a definite association with hepatitis C. It is postulated that the virus may also induce a malignant transformation. We describe an unusual presentation of a case of asymptomatic left hepatic mass in a patient with hepatitis C with a preoperative diagnosis of hepatocellular carcinoma. He underwent a left lateral segmentectomy, and the pathologic examination revealed non-Hodgkin's lymphoma. The clinical features, radiologic investigations, and pathologic findings are presented. A review of the literature discussing clinical features, postulated pathogenetic mechanisms, and management options is also presented.
