This report describes a case of POEMS syndrome with extremely rare com
plications of thrombocytopenia and biliverdinaemia. The thrombocytopen
ia appeared to be due to immunopathogenesis. Steroid treatment resulte
d in complete disappearance of the biliverdinaemia in this patient as
well as symptoms and signs of POEMS syndrome, suggesting that the bili
verdinaemia was related to POEMS syndrome.
