title: Hepatic histopathology in the acquired immunodeficiency syndrome.
abstract: Involvement of the liver with the same opportunistic organisms and neoplasms affecting other organs has been recognized since the beginning of the AIDS epidemic. In this overview of hepatic histopathologic features in AIDS, we review the range of opportunistic infections and neoplasms accompanying HIV infection. Hepatic disease may result from viral, bacterial, protozoal, or fungal infection, or secondary to drugs and neoplasms. Liver involvement in AIDS usually reflects disseminated rather than primary disease. CMV and mycobacteria are the most common organisms in liver identified in biopsy and autopsy studies. A variety of nonspecific features, including steatosis, granulomas, and sinusoidal abnormalities may also be seen. HIV-1 itself was recently identified in the liver. Speculation regarding the significance of this finding has been discussed in this review. Hepatitis B, C, and D may also complicate the course of disease in patients with AIDS. Hepatitis B behaves differently in the population with AIDS than in immunocompetent patients. We concluded our review with a discussion of the present recommendations regarding the use of liver biopsies in these patients. This topic continues to be widely debated in the literature.
