Diffuse Large B-cell Lymphoma with Severe Lactic Acidosis and Liver Failure: A Case Report and Literature Review.

Among causes of liver failure, liver failure due to lymphocytic infiltration is rare. Unlike typical liver failure, some cases present with severe lactic acidosis and a poor prognosis. We herein report a case of diffuse large B-cell lymphoma with severe lactic acidosis and liver failure. We further discuss the characteristics of similar cases in the literature, suggesting that intrahepatic infiltration by hematological malignant cells should be considered as a differential diagnosis in the presence of severe lactic acidosis and liver failure. This study underscores the importance of early recognition and serves as a reference for future cases.
