Plasma Cell Leukemia Presenting as Organizing Pneumonia Refractory to High-Dose Steroid Therapy

Abstract

A case of steroid-refractory organizing pneumonia (OP) as the initial presentation of plasma cell leukemia (PCL) in a patient who had no prior exposure to chemotherapy or radiation is described. Since OP is traditionally a steroid-responsive disease, this case raises the possibility of a previously unknown patient subgroup with variable disease pattern and/or behavior in patients with plasma cell neoplasm.
