Abstract

Cold agglutinin syndrome is a rare form of autoimmune hemolytic anemia, accounting for 20% of all autoimmune hemolytic anemia. In this entity, red blood cell lysis is mediated by complement activation. This hemolysis occurs at temperatures below 37 ° C. The presentation can be idiopathic or secondary and its treatment is related to the cause. Treatment consists of steroid-based regimens associated with cyclophosphamide or chlorambucil and immunotherapy such as rituximab. A 53-year-old female patient is presented, who attends the hematology service of the Center for Surgical Medical Research due to presenting marked decay. When carrying out complementary studies, a monoclonal gammopathy and a positive direct Coomb test were found, with high titers of IgM-type cold agglutinins. The definitive diagnosis was made post-mortem, which revealed a small lymphocytic non-Hodgkin lymphoma.
