title: [Acute myeloid leukemia presenting with obstructive jaundice and granulocytic sarcoma of the common bile duct].
abstract: A 55-year-old man presented with jaundice and edema of the right leg. Tests of the peripheral blood and bone marrow showed leukocytopenia with 6% blasts and 38.3% of myeloperoxidase-positive blasts, respectively. Computed tomography (CT) scanning disclosed thickening of the common bile duct wall. Granulocytic sarcomas were also found at the left chest wall and the pelvic floor. Endoscopic retrograde cholangiopancreatography confirmed the narrowing of the common bile duct. Biopsy specimens of the common bile duct and pelvic masses revealed myeloblastic infiltration. After placement of a naso-biliary drainage tube, chemotherapy consisting of cytarabine (100 mg/m2/ day for 7 days) and idarubicin (12 mg/m2/ day for 3 days) was commenced. The dose of idarubicin was not modified. No serious complications, including delayed hematopoietic recovery, were observed after chemotherapy, and a complete remission was obtained 35 days later. Jaundice and liver dysfunction also gradually improved. The patient continues to receive consolidation therapy and remains in remission 8 months after the onset of his illness.
