Radiology-pathology conference: Robert Wood Johnson Medical School. Eosinophilic granuloma of the lung.

Eosinophilic granuloma of the lung is a nodular infiltration of the interstitium of the lung by histiocytes, plasma cells, lymphocytes, and eosinophils. While radiologic findings of nodules and small cystic spaces of the upper lung zones are present, surgical biopsy is required for diagnosis.
