title: Pulmonary cysts in progressive systemic sclerosis (scleroderma).
abstract: A young man with progressive systemic sclerosis (PSS) and pulmonary complaints exhibited enlarging lung cysts on chest x-ray. These rather uncommon findings in PSS result from alveolar dissolution and obstructive emphysema. Diffuse pulmonary fibrosis is basic to this process as well as to the more familiar pulmonary roentgen changes in PSS.
