Diffuse panbronchiolitis is a disease largely restricted geographically to Japan. It is manifested clinically by an insidious onset of dyspnea, cough, and production of mucopurulent sputum. Histologically it is characterized by a suppurative bronchiolitis involving primarily the respiratory and terminal bronchioles with subsequent progression to bronchiolectasis. Pulmonary function tests show a mixed obstructive-restrictive pattern. This report presents two cases occurring in white patients and one in an Oriental immigrant to Canada.

Diffuse panbronchiolitis (DPB) is a disease with chronic inflammation exclusively located in the region of respiratory bronchioles. The pathologic features of the disease are characterized by thickening of the wall of the respiratory bronchiole with infiltration of lymphocytes, plasma cells and histiocytes, and extension of the inflammatory changes toward peribronchiolar tissues. In the advanced stage, secondary ectasia of proximal bronchioli may occur. These changes appear as diffusely disseminated small nodular shadows throughout both lungs on the chest roentgenogram. Obstructive respiratory functional impairment, occasional symptoms of wheezing, and also cough and sputum resemble the feature of emphysema, bronchial asthma, or chronic bronchitis, respectively. In the advanced stage, large amounts of purulent sputum and dilatation of proximal terminal conducting bronchioli resemble bronchiectasis. However, diffuse panbronchiolitis belongs to a distinctly different category from these diseases, and should be distinguished from them, because it may often show rapid progression with fatal outcome. The disease is dominant in males and the onset is unrelated to age. More than 1,000 cases of probable diffuse panbronchiolitis and 82 histologically-confirmed cases have been collected in Japan.

Diffuse panbronchiolitis (DPB), an important cause of progressive obstructive lung disease in the Far East, represents a distinctive sinobronchial syndrome with typical radiologic and histologic features. We have identified DPB in five citizens of the United States, three with histologic confirmation, who have never traveled to the Far East. There were four men and one woman, whose ages ranged from 46 to 75 yr at the time of diagnosis. All had a prior history of chronic sinusitis and presented with cough, dyspnea, and sputum production. Three were never smokers and two were current smokers. Pulmonary function testing revealed severe airflow limitation (the FEV1 ranging from 22% to 56% of predicted), and overdistention. All patients had high-resolution computed tomographic (HRCT) scans indicating centrilobular nodules with adjoining thickened and dilated bronchioles. In the three patients in whom open lung biopsy was performed, there was bronchiolocentric infiltration of lymphocytes, plasma cells, and foamy macrophages. Three patients remain alive and are being treated with chronic macrolide therapy. The clinical, radiographic, and histologic features of these patients closely resemble those described in Japanese patients. DPB must be considered in the differential diagnosis of sinopulmonary syndromes, bronchiolitis, and cryptic cases of obstructive lung disease among United States citizens, since therapy now offers an improved prognosis.
