It is primarily regarded as a severe subtype of idiopathic multicentric Castleman disease (iMCD), referred to as iMCD-TAFRO. Others believe that TAFRO could be either a clinical entity overlapping with iMCD or a unique autoimmune or inflammatory disease that can be accompanied by an iMCD-like lymph node histopathology (2). Patients with iMCD-TAFRO have a different cytokine spectrum and unusual clinical manifestations (including thrombocytopenia, anasarca, and renal dysfunction) compared with patients with iMCD without TAFRO, referred to as iMCD not otherwise specified ...References1.
