[Churg-Strauss syndrome. Its nosological place. Apropos of a new case diagnosed before death].

Allergic granulomatous angeitis or Churg and Strauss disease, seems to form part of the disease of necrotising angeitis. Clinically, it may be considered when periarteritis nodosa is associated with asthma and marked eosinophilia. The diagnosis depends on the pathological findings including the venous and pulmonary lesions, giant cells and the presence of extra-vascular granulomas. The recognition of this disease does not, however, permit one to give a precise prognosis. In the absence of progress concerning the pathogenesis, treatment will be the same as that given in other forms of necrotising angeitis.
