TAFRO syndrome is characterized by the presence of thrombocytopenia, anasarca, fever, reticular myelofibrosis, organomegaly, and is frequently associated with kidney damage in the form of membranoproliferative glomerulonephritis (MPGN) or thrombotic microangiopathy (TMA). Treatment is based on corticosteroids. A 59-year-old man who suffered from heart disease, pancytopenia and hepatosplenomegaly of unknown etiology developed nephrotic syndrome and progressive renal insufficiency, with a kidney biopsy suggestive of MPGN with a "full-house" immunofluorescence pattern. Positron emission tomography (PET) revealed multiple lymphadenopathies which histologically were compatible with multicentric Castleman's disease. The patient was diagnosed with TAFRO syndrome and treatment with siltuximab was started, with evident improvement at 3 months. TAFRO syndrome is a rare entity which may present with severe kidney involvement and histological findings of MPGN or TMA, with or without immune complex deposits. Our case suggests that a corticosteroid-free regimen with siltuximab could be an attractive therapeutic option.

Castleman disease is a rare lymphoproliferative disorder. It presents with localized or generalized lymph node enlargement with a multitude of inflammatory symptoms. The etiology is largely unknown; however, human herpes virus 8 and Interleukin 6 have been found to be associated with some of these cases.

Renal pathology is typically characterized by glomerular microangiopathy without immune deposits, and there have been no reports of membranous nephropathy. While idiopathic multicentric Castleman disease (iMCD), which shares a similar pathophysiology with TAFRO syndrome, has documented several cases of membranous nephropathy, the underlying mechanisms remain unclear.

We describe a rare case of thrombocytopenia, anasarca, fever, reticulum fibrosis, and organomegaly (TAFRO) syndrome that developed after the second vaccination against SARS-CoV-2 (mRNA1273, manufactured by Moderna Co.) in a healthy 26-year-old male. He developed a prolonged high fever and intermittent non-localised abdominal pain soon after vaccination followed by impaired renal function and thrombocytopenia; as well as assumed cytokine storm due to serum levels of triglyceride and total cholesterol, and high serum levels of ferritin, soluble interleukin 2 receptor, soluble CD14, interleukin 6, and vascular endothelial growth factor.

Rationale: Castleman disease (CD) is a rare lymphoproliferative disorder characterized by nonmalignant lymph node enlargement, often associated with systemic symptoms. It is classified into unicentric disease (involving a single enlarged lymph node) and multicentric disease (affecting multiple lymph node stations). In some cases of idiopathic multicentric Castleman disease (iMCD), elevated levels of various serum inflammatory markers are observed, and histologically, the lymph node enlargement resembles that caused by autoimmune diseases, making diagnosis challenging.
