Diffuse panbronchiolitis (DPB) is a unusual form of bronchiolar disease that has been reported almost exclusively in Asians. We describe DPB in a non-Asian Brazilian citizen who has never traveled outside the country. The clinical, radiographic, and histologic features of this case resemble those described in Japanese patients. The present case shows that DPB, although rare in Western countries, is not a disease restricted to Asia. It always should be considered in the differential diagnosis of nodular radiographic opacities associated with airflow limitation, especially in non-smokers with a history of chronic sinusitis.
