Abstract

Non-idiopathic pleuroparenchymal fibroelastosis (PPFE) has been increasingly reported in the literature. Little is known about the clinical relevance of PFFE and hypersensitivity pneumonitis (HP) overlap; therefore, we sought to investigate the clinical, radiological, and pathological features of patients with these two diseases. Five patients were identified, and the detailed characterization of these cases revealed a heterogeneous group in terms of clinical and treatment options. No mortality, acute exacerbations, or a significant decline in lung function were verified. Our cases seem to have a more “benign” disease behavior, contrary to previous idiopathic PPFE studies. More studies are needed to corroborate these findings and to better elucidate the clinical significance of PPFE and HP overlap.

Keywords: hypersensitivity pneumonitis, pleuroparenchymal fibroelastosis, idiopathic interstitial pneumonia
