[Hepatic involvement in the acquired immunodeficiency syndrome. Study of 20 cases].

Liver biopsies were systematically performed in 20 patients with evidence of an acquired immunodeficiency syndrome (18 with opportunistic infections, 9 with Kaposi's sarcoma). Hepatitis, related to hepatitis-B virus in 3 cases and to cytomegalovirus in 3 cases, was present in 6 of them. All patients had at least one of the three following lesions: non-specific portal inflammatory infiltration (6 cases), granulomatous lesions (12 cases), vascular abnormalities (12 cases). Among hepatic granulomatous lesions: 3 were due to acid-fast bacilli and 1 to Cryptococcus. Sinusoidal abnormality included proliferation of Küpffer cells (9 cases), sinusoidal dilatation (2 cases), peliosis (4 cases) and Kaposi's sarcoma (1 case). A relationship between these abnormalities cannot be excluded.
