Angioimmunoblastic T-cell lymphoma (AITL) is frequently associated with immunological abnormalities, such as hypergammaglobulinemia, autoimmune cytopenia, and the presence of various autoantibodies. Few reports on AITL have also described the development of myelofibrosis resulting from the invasion of lymphoma cells that produced various cytokines, including TGF-β. Interestingly, recent studies demonstrated that autoimmunity can directly cause autoimmune myelofibrosis (AIMF). Usually, bone marrow fibrosis associated with AIMF is rapidly improved by treatment. Here, we describe our experience with a case of AITL complicated with the presence of numerous autoimmune abnormalities, including positive Coombs, anti-nuclear antibody, anti-ds-DNA antibody, anti-phospholipid antibody, and cold agglutinin tests. The patient presented with severe bone marrow fibrosis (MF-3) at the initial diagnosis. After two courses of the CHASE therapy, myelofibrosis rapidly disappeared, and the autoimmune abnormalities were ameliorated. These findings suggest that the bone marrow fibrosis observed in this case was partly attributable to an AIMF-like mechanism.
