Primary lymphoma of the liver in the acquired immunodeficiency syndrome.

We describe a 78-year-old man with a diffuse large-cell lymphoma that was limited to the liver and was associated with micronodular cirrhosis and Kaposi's sarcoma that involved abdominal lymph nodes and gastric mucosa. The serum of the patient reacted positively to a test for human T-cell lymphotropic virus type III antibodies. We discuss the clinical and autopsy findings for this unusual patient, the criteria for the diagnosis of primary lymphoma of the liver, and its occurrence in patients with the acquired immunodeficiency syndrome.
