Chromosome analysis showed t (8;14)(q24;q32) and t (11;14)(q13;q32). Treatment with daratumumab, lenalidomide, and dexamethasone resulted in partial response, but the disease relapsed, with a copy number increase in t (11;14) and abnormal amplification of the 1q21 region. The patient was treated for CMV enteritis, and was admitted to the hospital due to sudden abdominal pain. Gastrointestinal perforation was diagnosed by CT scan showing free air and wall thickening in the small intestine. Emergency surgery was performed, and the tumors in the perforated area were positive for CCND1 but negative for MYC on immunostaining. The patient's general condition did not improve after the surgery and he died. Pathological autopsy revealed extramedullary infiltration of multiple organs in addition to the small intestine. Extramedullary infiltration is thought to be caused by clonal evolution, and further research is warranted to clarify its pathogenesis and establish effective therapeutic strategies in high-risk patients.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141499874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Primary CAD is a clonal B-cell lymphoproliferative disease of the bone marrow that produces IgM type-M protein, while conventional secondary CAD is cold agglutinin syndrome (CAS). Clinical findings are broadly classified into chronic anemia due to hemolysis and symptoms associated with peripheral circulatory failure due to erythrocyte aggregation under cold exposure. Not all patients require drug therapy, but monoclonal antibody therapy against complement C1s is preferred for the former presentation and B-cell suppressors for the latter. As cold AIHA is treated differently than warm AIHA, misdiagnosis can significantly impact the outcome of treatment. The most important aspect of blood testing is temperature control of specimens. Cold agglutinin titer, IgM quantification, electrophoresis, and immunofixation methods may produce false-negative results if the serum is not temperature-controlled at 37-38°C until serum separation. Correct handling of specimens, along with knowledge of the various clinical features of CAD, will lead to correct diagnosis and appropriate treatment.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141499870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, relapse of ATL was detected on day 74 post-transplantation, as evidenced by the rapid growth of lymphoma cells in peripheral blood and an increase in soluble interleukin-2 receptor (sIL2R) levels. Discontinuation of immunosuppressant therapy alone did not improve ATL findings, but treatment with lenalidomide caused lymphoma cells to disappear from the peripheral blood and sIL2R levels to return to normal. Pancytopenia was observed as a lenalidomide-associated adverse effect, but lymphocyte counts were not reduced. The patient was judged to be in complete remission based on results of Southern blot analysis and human T-cell leukemia virus 1 (HTLV-1)-infected cell analysis using flow cytometry (HAS-Flow). Flow cytometric analysis of peripheral blood and FISH analysis of X and Y chromosomes revealed that the therapeutic effect of lenalidomide was associated with an increase in the number of donor-derived peripheral natural killer cells. ATL relapse was not observed at 13 months into lenalidomide treatment. Our results suggest that lenalidomide is an effective option for the treatment of post-transplant relapsed ATL.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141891240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Congenital thrombotic thrombocytopenic purpura (cTTP) was suspected on the basis of recurrent thrombocytopenia and impaired consciousness, so tests for ADAMTS13 activity and inhibitor were performed. ADAMTS13 activity was severely decreased, ADAMTS13 inhibitor was negative, and platelet count increased after transfusion of fresh frozen plasma. These findings and the results of genetic testing done on all family members led to a diagnosis of cTTP. cTTP requires differential diagnosis even in adults. If a patient diagnosed with ITP in childhood has a history or findings that suggest cTTP during follow-up observation, it is necessary to actively consider ADAMTS13 testing.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140856864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
