Peripheral hypothyroidism and TAFRO syndrome: Particularity of management

Abstract

TAFRO syndrome is defined by the presence of thrombocytopenia, hydrops, fever, fibrosis, renal dysfunction, and organomegaly and can be seen with idiopathic multicentric Castleman disease (iMCD) or as an isolated process without iMCD. The pathophysiology of TAFRO is not well understood, but it is thought to be related to hypercytokinemia. Subclinical hypothyroidism may be a potential factor in the pathogenesis and symptomatology of TAFRO syndrome with elevated vascular endothelial growth factor (VEGF).There are no clear guidelines for the treatment of TAFRO in the absence of a definitive diagnosis of iMCD, resulting in suboptimal management and high morbidity. We report a case of hypothyroidism revealed by TAFRO syndrome.
