Idiopathic Multicentric Castleman Disease With Thrombocytopenia, Anasarca, Fever, Reticulin Fibrosis/Renal Insufficiency, and Organomegaly (TAFRO) Syndrome in a Liver Transplant Recipient.

Idiopathic multicentric Castleman disease is a rare lymphoproliferative disorder that can be potentially fatal without timely diagnosis and treatment. We describe the first-ever reported occurrence of idiopathic multicentric Castleman disease with thrombocytopenia, anasarca, fever, reticulin fibrosis/renal insufficiency, and organomegaly syndrome in a liver transplant recipient. The diagnosis was challenging as the clinical presentation closely mimicked decompensated cirrhosis, and the profound thrombocytopenia limited tissue diagnosis. However, we were able to establish the diagnosis and treat it effectively. This case report signifies that a high index of suspicion and aggressive treatment can be lifesaving in liver transplant recipients presenting with this rare disorder.
