The primary pulmonary manifestation of chronic graft vs host disease (GvHD) is the development of bronchiolitis obliterans. Other pulmonary manifestations of chronic GvHD that have been reported include diffuse alveolar damage, lymphocytic interstitial pneumonia, bronchiolitis organising pneumonia and lymphocytic bronchiolitis/bronchitis.We report an unusual case of a 34-year-old patient with acute myeloid leukaemia, status post-allogenic hematopoietic stem cell transplantation who subsequently developed GvHD with skin involvement. He presented to our hospital with new onset respiratory failure and on subsequent surgical lung biopsy was found to have non-specific interstitial pneumonia (NSIP).This is the third case of a patient with biopsy-proven GvHD who had NSIP pattern on surgical lung biopsy. We believe this may represent a rare manifestation of pulmonary GvHD.
