title: Case report. Progressive systemic sclerosis presenting as interstitial pulmonary fibrosis.
abstract: Pulmonary involvement usually is a late manifestation of progressive systemic sclerosis. In the case reported here, dyspnea and pulmonary interstitial fibrosis developed more than a year prior to onset of skin and vascular changes. Open-lung biopsy performed early in the course of the disease failed to yield a definitive diagnosis.
