Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus-2. Patients with hematologic malignancies have been shown to have higher risk of mortality due to COVID-19 than reported in the general adult population. Reports on acute lymphoblastic leukemia and COVID in children are scarce. We present a case of an 11-year-old male patient undergoing treatment for B-cell acute lymphoblastic leukemia with an atypical course of COVID-19. The patient received a positive result of the syndrome coronavirus-2 polymerase chain reaction test performed due to epidemiologic reasons. The chemotherapy was continued since the patient had no clinical signs of COVID-19. The disease started with intensive gastrointestinal bleeding, followed by severe respiratory tract infection over 2 weeks later.
