Diffuse panbronchiolitis in a Hispanic man with travel history to Japan.

Diffuse panbronchiolitis is a chronic airflow disorder of obscure origin, which has been reported infrequently outside of Japan and never with any long-term follow-up. We report such a case in a Hispanic man. Furthermore, this patient had an extensive travel history to the Far East, including Japan. This case raises the possibility of a poorly transmissible infectious agent responsible for the disease.
