[A Case of Rapidly Progressing High-grade B-cell Lymphoma with c-Myc Translocation and Bcl-2 Protein Expression].

We report a case of rapidly progressing primary high-grade B-cell lymphoma of the central nervous system with c-Myc translocation and Bcl-2 protein expression that resulted in the patient's death 45 days after the onset of convulsions. Further, we provide a literature review. CASE:A 74-year-old man was admitted to our hospital for convulsions. Magnetic resonance imaging on admission showed tumorous lesions at the left temporoparietal junction. An open biopsy was performed promptly. The patient was diagnosed with primary high-grade B-cell lymphoma of the central nervous system with c-Myc translocation and Bcl-2 protein expression(<50%). The tumor showed rapid progression postoperatively. The patient did not respond to steroids and died 45 days after the onset of convulsions. CONCLUSION:The c-Myc translocation, showing a strong c-Myc protein positivity, and co-expression of the Bcl-2 protein were poor prognostic factors for the tumor.
