  • Title: Kupffer cells in hepatocellular adenomas.
    Author: Goodman ZD, Mikel UV, Lubbers PR, Ros PR, Langloss JM, Ishak KG.
    Journal: Am J Surg Pathol; 1987 Mar; 11(3):191-6. PubMed ID: 3030147.
    Abstract:
    Hepatocellular adenomas are usually visualized as defects on technetium-99m-sulfur colloid liver scans, a fact which has been attributed to the absence of phagocytic Kupffer cells in the tumors. To determine whether this is true, seven hepatocellular adenomas were subjected to immunoperoxidase staining for lysozyme, a marker of mononuclear phagocytes. The Kupffer cells were counted in the tumors and surrounding non-neoplastic liver. All hepatocellular adenomas studied were found to contain Kupffer cells. Three tumors had fewer Kupffer cells than the surrounding liver. Three had about the same number as the surrounding liver, and one had more Kupffer cells than the non-neoplastic liver. Thus, the lack of phagocytosis of colloid in liver scans is probably due to something other than a deficiency of Kupffer cells in the hepatocellular adenomas.
