[Acute myocardial infarction as Eosinophilic granulomatosis with polyangiitis (formerly Churg Strauss syndrome) initial presentation]

Abstract

Eosinophilic granulomatosis with polyangiitis is a rare primary vasculitic disease characterized by hypereosinophilia, late onset asthma and extravascular eosinophil granulomas. We report a case presented initially with acute myocardial infarction which later only proceed with asthma, skin manifestations and peripheral neuropathy. Laboratory parameters showed hypereosinohpilia with negative perinuclear pattern of antineutrophil cytoplasmic autoantibodies (p-ANCA). Skin biopsy showed leucocytoclastic vasculitis with eosinophilic infiltration while coronary angiography was normal. The patient's symptoms improved with IV methylprednisolone, pulse cyclophosphamide and azathioprine.
