Castleman's disease with TAFRO syndrome: a case report from Syria

Castleman's disease is a rare disorder, yet a rarer newly described syndrome called TAFRO syndrome was discovered to accompany it. TAFRO represents the constellation of symptoms (Thrombocytopenia, Anasarca, MyeloFibrosis, Renal failure, Organomegaly). Most cases were described in Japan. We present the first case of TAFRO syndrome in Syria. A 58-year-old Caucasian male with no relevant history presented with fatigue, oliguria, decreased platelets, increased creatinine level, hepatosplenomegaly, ascites, pitting edema and lymph node enlargement. Possible differential diagnoses were excluded by laboratory, radiologic and cytologic tests including TB, malignancy and autoimmune diseases. A biopsy of a supraclavicular lymph node confirmed Castleman disease. Our patient had Catleman's disease, and presented with only four diagnostic criteria for TAFRO syndrome (Myelofibrosis was absent) in addition to other minor characteristics (microcytic anemia, negative HIV and HHV-8 infections.) which make the presentation consistent with TAFRO syndrome described in the Japanese cases. The criteria for diagnosing TAFRO syndrome are still changing, and the pathophysiology behind it is unclear. We recommend further research to understand this syndrome taking into account that its prevalence might be worldwide.
