Hyperlactemia is a rare and potentially fatal complication of
hematologic malignancies, as well as an oncological emergency, which
requires a fast diagnosis and early therapeutic management, as these
interventions may alter disease prognosis. Herein, we present a case of
secondary liver-biopsy-confirmed diffuse large B-cell lymphoma (DLBCL),
presented with elevated liver enzymes and lactic acidosis, without
depicted hepatic lesions, hepatosplenomegaly, or enlarged lymph nodes on
computed tomography. This case confirms the poor prognosis of cases with
delayed diagnostic intervention and highlights the importance of early
clinical suspicion, liver biopsy, and prompt treatment initiation
