ABSTRACT
Plasmablastic lymphoma is a rare and a relatively new entity that was first described in the jaws and the oral cavity of HIV-AIDS patients. We report a case of plasmablastic lymphoma involving the liver in an AIDS patient. Plasmablastic lymphoma is considered a diffuse large B-cell lymphoma with a unique phenotype and predilection for the oral cavity. The case presented had a unique hepatic lesion, localized in the left lobe of the liver. Diagnosis was confirmed by hepatic biopsy guided by Computerized Tomography scan and histopathology. The smears showed a dense infiltrate composed by atypical lymphocytes with numerous plasmocytes expressing the plasma cell markers MUM-1 and CD138 and negative for the B-cell markers CD3, CD20 and CD45. Immunohistochemical and in situ hibridization revealed the Epstein-Barr virus genome in the atypical cells. Polymerase chain reaction was negative for HHV-8 RNA.
