摘要

Pure red cell aplasia (PRCA) is a rare hematological disorder characterized by erythroid hypoplasia and maturation arrest in the bone marrow. We present a case of acquired PRCA secondary to smoldering multiple myeloma (SMM), initially presenting as severe anemia requiring multiple blood transfusions. This case highlights the diagnostic dilemma at presentation as well as the therapeutic challenges in treating PRCA secondary to SMM. Here we discuss the appropriate workup and identify a potential option for managing these patients with subcutaenous daratumumab.
