%X A 43-year-old man with pancytopenia was diagnosed with acute promyelocytic leukemia (APL). On the first day of induction therapy with all-trans retinoic acid (ATRA) alone, he presented with high fever and was found to have coronavirus disease 2019 (COVID-19) infection by SARS-CoV2 antigen test. While it is generally recommended to delay treatment for APL patients with COVID-19 unless urgent APL treatment is required, this patient needed to continue treatment due to APL-induced disseminated intravascular coagulation (DIC). Considering the challenge of distinguishing between differentiation syndrome (DS) and COVID-19 exacerbation, the ATRA dosage was reduced to 50%. The patient was able to continue treatment without development of DS or exacerbation of DIC, leading to his recovery from COVID-19 and remission of APL.
