[Anatomopathology of pulmonary granulomatoses]

Pulmonary granulomatosis are lung diseases due to inflammatory lesions with characteristic histiocyte reactions seen in granulomas often composed of epithelioid and giant cell formations. There are a number of pathological entities depending upon whether the aetiology is infectious or immunologic. The pathologist is asked to determine the type of reaction and to identify the greatest number of elements possible for the aetiologic diagnosis.
