Two types of cytomembranous abnormalities were identified for the first time in liver biopsies from patients with chronic active type B hepatitis during treatment with recombinant α‐interferon. Tubuloreticular inclusions were present in the hepatic endothelial cells, Kupffer cells and perisinusoidal cells of liver biopsies from both patients, and they were absent in liver biopsies obtained before treatment. Cylindrical confronting lamellae, having “test tube” or “ring‐shape” forms were observed in the cytoplasm both of Kupffer cells and macrophages in the second liver biopsy of one of the patients. The findings suggest that interferon can be involved in the pathogenesis of both cytomembranous abnormalities, but that additional biological factors may play a role in formation of the cylindrical confronting lamellae.
