 AB    We report a case of a man positive for the human immunodeficiency virus
       who rapidly died of lymphoma with cerebral, lung, and pericardic
       involvement. After autopsy, histopathological study of the different
       tumor sites showed the same morphological feature of immunoblastic
       lymphoma, with large areas of necrosis. In situ hybridization showed
       monotypic kappa light chain mRNA within lung lymphoma cells and
       monotypic lambda light chain mRNA within cerebral lymphoma cells.
       Polymerase chain reaction analysis showed two different immunoglobulin
       heavy chain gene rearrangements for lung and cerebral lymphoma. Here the
       simultaneous association of two malignant lymphomas derived from
       different B-cell clones indicates that molecular analysis of different
       tumor sites can distinguish between dissemination of the same lymphoma
       and simultaneous proliferation of different malignant B-cell clones.
