Linfoma difuso primario de hígado: Presentación de un caso

Diffuse primary hepatic lymphoma. Case report Primary hepatic lymphoma (PHL) is a rare tumor that represents less than 1% of extranodal non-Hodgkin B-cell lymphoma. We report a case of PHL in a 32 year-old male patient without chronic liver disease, who was admitted into our institution for suspected mononucleosis syndrome. Serology for Epstein-Barr virus was positive. Ultrasound revealed hepatosplenomegaly with diffuse heterogeneous liver parenchyma. The MRI showed hepatosplenomegaly and alterations in the right lobe of the liver compatible with lymphoproliferative infiltration. Liver biopsy was performed under ultrasound guidance, and histopathologic examination revealed a diffuse non-Hodgkin lymphoma of large cells with immunophenotype B. A clinical and a pathological case as well as a review of the clinical, pathological and radiological findings of this disease are presented.
