Electron microscopy of rejected human liver allografts
Robert H. Fennell, John M. Vierling – 1 November 1985 – Recognition by biopsy of liver allograft rejection has been less successful than diagnosis of rejection of cardiac and kidney allografts. In a study of 138 failed liver allografts, we recognized damage to small interlobular bile ducts by lymphocytes as the most useful indicator of the presence of rejection. This is a report of the electron microscopic features of three patients with unequivocal allograft rejection. Lymphocytes and occasional granulocytes penetrated the epithelia of interlobular bile ducts.
