Nine patients with chronic lymphocytic leukemia (CLL), with pulmonary involvement confirmed by biopsy, presented with progressive cough and/or shortness of breath and had interstitial infiltrates on chest radiographs. Biopsies showed a dense lymphocytic infiltrate that followed bronchovascular bundles. We considered CLL the predominant finding, and the cause of the patient's pulmonary disease, in eight cases; in one, a histologically non-specific organizing pneumonia was the main lesion and CLL was an incidental finding. Culture results were available in six cases and were negative except in one case with presumed contaminants. A granulomatous reaction was present in five cases and was necrotizing in two, although culture results were negative. The only case with a recognizable organism had noninvasive fungal hyphae growing in many of the small airways. All of the patients' respiratory symptoms improved after chemotherapy and/or steroid therapy, and the chest radiographs also showed clearing.
