An 83-year-old woman with fatigue and weight loss was found to have cold agglutinin disease. She had a remote history of diffuse large B-cell lymphoma treated with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) chemotherapy. Clinically, she had no predisposing infections and no lymphadenopathy or splenomegaly. / Her hemoglobin was 71 g/L, leukocyte count 10.5 × 109/L, and platelet count 195 × 109/L. There was evidence of hemolysis (elevated LDH [lactate dehydrogenase], indirect bilirubin, and reticulocytes), and a direct antiglobulin test was positive for C3 coating the red cells. Cold agglutinins were present with a titer of 1:1024 at 4°C. The peripheral smear showed red cell agglutinates (see arrows) and an infrequent atypical lymphocyte (panel A). Serum protein electrophoresis with immunofixation demonstrated a monoclonal IgM level of 3.6 g/L. The computed tomography (CT) of the thorax, abdomen, and pelvis showed no evidence of an underlying lymphoproliferative disorder. She was treated with chlorambucil followed by rituximab with a good response to the latter. / Five months later she developed severe hypotension and abdominal pain. Ultrasonography suggested cholecystitis that required an urgent cholecystectomy. Peripheral blood smear showed agglutinated red cells (panel B) and a population of large monomorphic lymphocytes. Flow cytometry of the blood revealed a monoclonal B-cell population expressing CD19/CD5, CD20, FMC7, and κ light chains. Pathology of the gallbladder showed diffuse infiltration of the wall with large lymphoid cells of similar immunophenotype in keeping with diffuse large B-cell lymphoma that relapsed. / Cold agglutinins can be associated with a viral or mycoplasma infection but should raise the suspicion of an associated malignancy. The blood films provided a clue to the presence of the relapsed lymphoma responsible for this patient's cold agglutinins.
