All-trans retinoic acid (ATRA) is used as standard induction therapy for acute promyelocytic leukemia (APL), but it is contraindicated for patients on hemodialysis. We present a case of a patient with APL on hemodialysis, intubated, and with marked disseminated intravascular coagulation (DIC) who was successfully treated with ATRA. A 49-year-old man was transferred to our hospital and admitted into the intensive care unit due to renal dysfunction, DIC, and pneumonia. Promyelocytes were noted in the peripheral blood, and he was diagnosed with APL after bone-marrow examination. Because of renal dysfunction, only Ara-C was used but with a reduced dose. The patient's condition improved, and he was extubated and withdrawn from dialysis on the 5th day of hospitalization. The patient suffered from APL syndrome during induction therapy, which necessitated ATRA withdrawal and steroid administration. Remission was achieved after induction therapy, and the patient is currently on maintenance therapy. There are few cases of patients with APL on hemodialysis who were treated with ATRA; hence, it is necessary to review the treatment plan for these patients.
