A 48-year-old man was transferred to our emergency room because of sudden-onset epigastric pain and nausea. Abdominal contrast-enhanced computed tomography (CT) showed splenomegaly with splenic infarction and intra-abdominal bleeding, suggestive of splenic rupture. An emergent open splenectomy was performed. His spleen was markedly swollen and showed continuous bleeding due to a laceration. On histopathological examination, his spleen was filled with abnormal tumor cells. He was diagnosed as having mantle cell lymphoma based on the findings of immunohistochemical and cytogenetic analyses of the spleen. Mantle cell lymphoma cells were identified in the bone marrow and ileum, and he was determined to be in stageIVA by positron emission tomography (PET)-CT. He was administered rituximab combined with hyper-CVAD/MA chemotherapy (R-hyper-CVAD/MA regimen). After two courses of the R-hyper-CVAD/MA regimen, he achieved complete response, as confirmed by PET-CT. He received four courses in total of the R-hyper-CVAD/MA regimen, followed sequentially by high-dose chemotherapy and autologous peripheral blood stem cell transplantation (auto-PBSCT). He is currently alive and free of disease. This is the 10th report of a mantle cell lymphoma case with spontaneous splenic rupture. We herein review previous reports and emphasize the importance of awareness of hematological malignancies when encountering a case with spontaneous splenic rupture.
