AIMS: Pulmonary sequelae, reported as chronic graft-versus-host disease (cGVHD), of haematopoietic stem cell transplantation (HSCT) include constrictive bronchiolitis obliterans (CBO), lymphocytic bronchiolitis (LB), and veno-occlusive disease (VOD); recently, pleuroparenchymal fibroelastosis (PPFE) has also been described in bone marrow transplant recipients. The histological features of pulmonary HSCT sequelae have not been described systematically. The aim of the study was to review and identify the histological features of PPFE after bone marrow transplant. METHODS AND RESULTS: A retrospective review of 20 patients who underwent lung transplantation for pulmonary disease following HSCT between 2004 and 2013 was conducted. The patient age at transplantation ranged from 8 years to 57 years (median, 27.5 years). Fifteen patients had cGVHD in other organs (skin, nine; liver, six; salivary gland, six). Lung transplantation was performed at a median of 4.6 years (range, 1.2-14.8 years) post-HSCT. Histologically, all cases had CBO, with concurrent LB in 10, and VOD in three. PPFE was identified in 15 cases (75%), with subpleural (15), paraseptal (11) and centrilobular (13) distributions; and non-specific interstitial pneumonia (NSIP) was identified in 15 cases (75%), with fibrotic (nine) and cellular (six) patterns. PPFE was distributed in all lobes, with a predominance in the upper lobe. NSIP was mostly focal, with two cases having diffuse involvement. CONCLUSIONS: PPFE and NSIP were frequently seen in HSCT patients. Possible causes may include reactions to drugs or radiation, or cGVHD.
