[Asthma, eosinophilia and systemic vasculitis: Churg-Strauss syndrome].

In two female patients asthma, marked eosinophilia and symptoms of systemic vasculitis could be classified clinically or histologically as allergic angiitis and granulomatosis (Churg-Strauss syndrome). The course in one patient went back over 20 years, characterized by an asymptomatic interval of 16 years. It is to be assumed that the disease is more frequent than it is diagnosed. It has to be thought of when, in addition to asthma and eosinophilia, there is evidence of involvement of other organs.
