TAFRO syndrome, first reported in 2010, is a systemic inflammatory disorder manifesting as thrombocytopenia; anasarca, including pleural effusion and ascites; fever; reticulin myelofibrosis and/or renal insufficiency; and organomegaly, including hepatosplenomegaly and lymphadenopathy. The annual incidence rate of TAFRO syndrome in Japan has been estimated to be 0.9–4.9 per million individuals, and the nationwide prevalence to be 860–7240 cases [1], numbers which are larger than previously expected. Most patients with TAFRO syndrome manifest modest-to-mild systemic lymphadenopathy with characteristic histopathological features resembling those of Castleman disease. Some researchers, therefore, consider that TAFRO syndrome to be a subtype of idiopathic multicentric Castleman disease (iMCD) [2]. However, clinical features of TAFRO syndrome are quite different from those of classical Castleman disease [3], and we consider TAFRO syndrome to be a distinct clinical entity, although several...
