Severe Lactic Acidosis in a Patient with B-Cell Lymphoma : A Case Report and Review of the Literature

الملخص EN

Lactic acidosis is commonly observed in clinical situations such as shock and sepsis, as a result of tissue hypoperfusion and hypoxia.

Lymphoma and leukemia are among other clinical situations where lactic acidosis has been reported.

We present a case of a 59-year-old female with lactic acidosis who was found to have aggressive B-cell lymphoma.

There have been 29 cases of lymphoma induced lactic acidosis reported thus far; however all reported cases have abnormal vital signs or concomitant medical conditions that may lead to lactic acidosis.

The pathogenesis of malignancy-induced lactic acidosis is not well understood; however associated factors include increased glycolysis, increased lactate production by cancer cells, and decreased hepatic clearance of lactate.

When it occurs, lactic acidosis is a poor prognostic sign in these patients.

Prompt diagnosis and treatment of underlying lymphoma or leukemia remains the only way to achieve complete resolution of lactic acidosis in these patients.
