Primary hepatic lymphoma presenting as pyogenic liver abscess: A case report

Abstract

BACKGROUND Primary hepatic lymphoma (PHL) is a lymphoproliferative disorder confined to the liver without peripheral lymph node involvement and bone marrow invasion. PHL is extremely rare in clinical practice. The etiology and pathogenesis of PHL are largely unknown. There are no common standard protocols or guidelines for the treatment of PHL. CASE SUMMARY We report the case of a 66-year-old man who presented with fever and abdominal pain for three weeks. Computed tomography and magnetic resonance imaging scans showed a pyogenic liver abscess. The patient underwent a right posterior hepatectomy. The surgical pathology revealed aggressive B-cell lymphoma, with a primary consideration of diffuse large B-cell lymphoma of non-germinal center origin. CONCLUSION This article reviews the characteristics, mechanism and treatment of PHL and provides insight into the diagnosis of PHL.
