Autoimmune hemolytic anemia (AIHA) is characterized by shortening of red blood cell (RBC) survival and the presence of autoantibodies directed against autologous RBCs. Approximately 20% of autoimmune hemolytic anemia cases are associated with cold-reactive antibody. About half of patients with AIHA have no underlying associated disease; these cases are termed primary or idiopathic. Secondary cases are associated with underlying diseases or with certain drugs. We report herein a rare case of cold autoimmiune hemolytic anemia due to high-grade non-Hodgkin's lymphoma of B-cell type with weak response to rituximab and chemotherapy regimens. For treatment B cell lymphoma, Due to lack of treatment response, we used chemotherapy regimens including R- CHOP for the first time, and then Hyper CVAD, R- ICE and ESHAP were administered, respectively. For treatment of autoimmune hemolytic anemia, we have used the corticosteroid, rituximab, plasmapheresis and blood transfusion and splenectomy. In spite of all attempts, the patient died of anemia and aggressive lymphoma nine months after diagnosis. To our knowledge, this is a rare report from cold autoimmune hemolytic anemia in combination with high-grade non-Hodgkin's lymphoma of B-cell type that is refractory to conventional therapies.

Autoimmune hemolytic anemia (AIHA) in childhood, including paroxysmal cold hemoglobinuria, is an uncommon, potentially life-threatening disorder. AIHA is a recognized complication of several varieties of lymphoproliferative disorders, including high-grade B-cell lymphoma, but it has not been associated with Burkitt lymphoma in people without an underlying immunodeficiency. When AIHA occurs in association with lymphoproliferative disorders, it may precede or accompany the diagnosis of malignant disease or herald relapse. We report a novel case of a previously healthy child diagnosed with paroxysmal cold hemoglobinuria 14 months preceding the development of Burkitt lymphoma.

Non-Hodgkin lymphoma (NHL) can co-exist with autoimmune hemolytic anemia (AIHA), a phenomenon known as AIHA-associated NHL (AIHA/NHL). However, few studies have reported AIHA/NHL incidence or its clinical characteristics. We conducted a retrospective analysis of 20 AIHA/NHL patients treated at our hospital from 2009 to 2018. AIHA/NHL was presented by only 0.91% of the NHL and 9.8% of the AIHA patients. In addition, AIHA occurred most frequently with angioimmunoblastic T-cell lymphoma (AITL) (7.31%), followed by marginal zone B-cell lymphoma (MZBL) (6.25%), B-cell lymphoma-unclassified (BCL-U) (4.25%), chronic lymphocytic leukemia/small lymphocyte lymphoma (CLL/SLL) (2.50%), and mantle cell lymphoma (MCL) (2.30%). In addition to the CLL/SLL patients with impaired bone marrow, 66.7% of the AIHA/NHL patients had lymphoma bone marrow infiltration (LBMI), of which 4 patients presented LBMI in bone marrow smears (BMS) but not in bone marrow biopsy (BMB) and 6 were positive for BMB but not BMS. The 1-, 3- and 5-year survival rates of AIHA/NHL patients were 70%, 30% and 20%, respectively, and they responded poorly to chemotherapy. In conclusion, AIHA can co-exist with various NHLs and the defining clinical characteristic of AIHA/NHL is the high incidence of LBMI. However, both BMS and BMB should be performed to avoid missed diagnosis.

Richter syndrome (RS) is the development of an aggressive lymphoma in patients with chronic lymphocytic leukemia (CLL). Most cases of diffuse large B-cell lymphoma variant of RS are clonally related to the original CLL. Here, we present a case of mantle cell lymphoma (MCL) that developed sequentially during the clinical course of CLL. A 72-year-old man had been diagnosed with CLL 16 years ago and was followed-up without treatment. He developed autoimmune hemolytic anemia 2 years ago, which resolved with rituximab and prednisolone treatment. Subsequently, he presented with fever, abdominal bloating, and fatigue. Progressive lymphocytosis and splenomegaly with elevated lactic dehydrogenase levels were suggestive of RS. Bone marrow examination revealed a small- to medium-sized lymphoid infiltrate, which was positive for CD5, CD20, CCND1, and SOX-11 and negative for CD23 and LEF1 on immunostaining. Fluorescence in situ hybridization analysis was positive for IgH/CCND1, which indicated MCL. Southern blot analysis showed that both the MCL and the previous CLL expressed different IgH gene rearrangement bands. At the time of relapse or progression of CLL, sequential development of MCL should be considered.
