Probable veno-occlusive disease after treatment with gemtuzumab ozogamicin in a patient with acute myeloid leukemia and a history of liver transplantation for familial hemochromatosis.

A 69-yr-old male with a history of familial hemochromatosis and status after liver transplantation was found to have severe thrombocytopenia (platelet count of 8000/microL). He was also anemic and was diagnosed with acute myeloid leukemia (AML) after a bone marrow biopsy. He was started on gemtuzumab ozogamicin (Mylotarg) and developed hepatic and multiorgan failure consistent with veno-occlusive disease within 2 wk.
