Abstract

To our knowledge, this is the first case report describing radiation recall dermatitis (RRD) after donor lymphocyte infusion post-allogeneic stem cell transplant in a patient with acute T-cell leukemia lymphoma. Given its rare occurrence, unclear clinical characterization, and etiology, RRD remains poorly understood. In the setting of novel immunotherapies and recent development of COVID-19 mRNA vaccines, we aimed to better characterize RRD and its most likely pathogenesis in our patient's case.
