| Abstract: | Ten patients with biopsy-proved eosinophilic granuloma of the lung were followed for periods of as long as nine years. The disease occurs as an isolated lung lesion or in association with bone lesions. The roentgenographic pulmonary findings are either diffuse nodularity or a fine reticular pattern. Symptoms are few, and pneumothorax is frequent. Scalene node and liver biopsies are usually not fruitful, and the diagnosis must be made by open or needle lung biopsy. Consistently abnormal laboratory tests are impaired single-breath carbon monoxide diffusing capacity and elevation of the alpha2 globulin protein fraction of serum.Treatment usually is not required; however, if deterioration occurs, the patient may benefit from corticosteroid therapy. |
