Introduction:We describe a female patient with extreme reactive thrombocytosis (RT) in anti-neutrophil cytoplasmic autoantibodies(ANCA)-associated crescentic glomerulonephritis (CGN) with immune complex deposits, which has never been reported before.Case Presentation: A female adolescent with symptoms of oliguria and gross hematuresis had serious renal function impairment(crescent formation andimmunecomplex deposits in renal pathology examination with positive serum ANCA) and extreme thrombocytosis.Wemadea diagnosis of CGNand RT. After treatment with Prednisone, Cyclophosphamide, and plasmapheresis, the symptomsof oliguriaandgross hematuresis were relieved remarkablyandtheserumcreatinineandplatelet count declined significantly.Conclusions: The diagnosis of thrombocytosis is not easy in all cases. The coexistence of ANCA and the immune complex in CGNmay cause a severe inflammatory state, leading to extreme RT. The roles that the immune complex and ANCA play on the effect ofthe platelet count and function in CGN need further research.
