Abstract
The thymus glands from 11 patients with aplastic anemia or acute leukemia who received allogeneic bone marrow transplants were studied at autopsy. All showed marked cortical involution. In the short-term survivors the medulla and perivascular spaces were lymphocyte-depleted and the epithelial cells formed pseudorosettes. In those surviving over 2 mo., increasing numbers of small lymphocytes were present, presumably reconstituted with donor lymphocytes. Phagocytosis of cellular debris was frequent, especially in patients with graft vs. host reaction (GVHR) or treated with antithymocyte globulin (ATG). Plasma cells were numerous in perilobular tissue and were occasionally found within the medulla. The thymus probably plays an important role in the immune deficiency experienced after allogeneic bone marrow transplantation and in the subsequent lymphoid reconstitution.This publication has 17 references indexed in Scilit:
