Acute lymphoblastic leukemia in an adolescent presenting with acute hepatic failure: A case report.

ABSTRACT

This case report describes a case of an unusual initial presentation of acute lymphoblastic leukemia in a previously healthy 15-year-old boy. He initially presented with a 6-day history of tiredness, decreased oral intake, nausea, vomiting, and jaundice (yellow sclera and dark urine) with evidence of acute hepatic failure, presenting as an increase in alanine aminotransferase (ALT)/aspartate aminotransferase (AST)/total bilirubin and a decrease in prothrombin activity. A complete serological evaluation for liver disease was negative. The levels of serum AST and ALT declined following hepatoprotective treatment. Bone marrow biopsy was diagnostic, revealing 68.15% blasts with markers consistent with acute B-cell lymphoblastic leukemia. This case report emphasizes that acute hepatic failure may be the initial presentation of ALL in an adolescent.
