Core Tip

Core Tip: Follicular lymphoma is an indolent lymphoma requiring immunochemotherapy with rituximab. This anti-CD20 monoclonal antibody depletes malignant and normal B-cells, resulting in a significantly increased risk of infectious complications, including the novel coronavirus, severe acute respiratory syndrome coronavirus 2 infection [coronavirus disease 2019 (COVID-19)]. We present the first case of mild COVID-19 in an elderly patient during ongoing follicular lymphoma treatment, without significant deterioration after rituximab administration. This case highlights that rituximab-based therapy may have no evident negative effect on the clinical course of COVID-19 in patients with follicular lymphoma, which may be significant during the current pandemic.
