Liver involvement by non Hodgkin's lymphoma usually represents systemic progression of a low grade lymphoma. Sixteen patients without palpable lymphadenopathy who presented with features suggesting hepatic inflammation were found to have non Hodgkin's lymphoma involving the liver.
Tissue sections stained with hematoxylin and eosin were examined by light microscopy. Immunohistochemical studies were performed on formalin-fixed paraffin embedded tissue to determine phenotype. Patients' medical records were reviewed for clinical details.
Clinical presentation included fever, jaundice, and elevated liver enzymes. Peripheral lymphadenopathy was absent. Hepatomegaly and splenomegaly were common. Imaging studies revealed a homogeneous pattern of liver involvement without a discrete mass. Histologically, infiltration of the liver was predominantly portal consisting of large, atypical cells scattered within a background of small lymphoid cells. By immunohistochemistry, it was determined that eight were T-cell and eight were B-cell lymphomas. Of the eight patients who had lymph node sampling, three showed involvement by diffuse mixed, small cleaved, and large cell lymphomas. Each of these three involved lymph nodes was located near the liver. Bone marrow infiltration was demonstrated in 10 of the 11 patients in whom it was sampled. Eleven of the 16 patients died 2 days to 31 months after diagnosis, and at last follow-up, 5 patients were alive 2 weeks to 13 months after diagnosis.
Patients with non-Hodgkin's lymphoma can present with hepatic dysfunction and without peripheral lymphadenopathy. This presentation of lymphoma is associated with extensive disease and an aggressive course.
