Abstract

We report a case of primary lymphoma of the liver successfully treated by major liver resection. The tumor exhibited the immunohistological features of a B-cell low-grade lymphoma of the lymphoplasmacytic type. Tumoral plasmacytic cells showed cytoplasmic-positive staining for IgG and kappa light chains. In addition, we detected a serum monoclonal peak of IgG kappa, a finding that has not been reported previously. Clinical, pathological, and immunohistochemical data from the literature are reviewed.
