INTRODUCTION: Organizing pneumonia (OP) is a well defined pathologic-clinical entity characterized by intra-alveolar accumulation of granulation tissue (1). The term “cryptogenic” is used when no aetiology is identified. The main treatment of OP is corticosteroids (CS), with generally rapid response, complete resolution of pulmonary infiltrates and normalization of lung function. However treatment of more aggressive, fibrosing forms of OP is not standardized. Mycophenolic acid (MPA) is the active component of mycophenolate mofetil, a reversible inhibitor of inosine-5′-monophosphate dehydrogenase. MPA is increasingly used as steroid sparing agent for interstitial lung disease (ILD) (2). We present a case series of biopsy-proven fibrosing OP leading to severe respiratory failure, with only partial response to CS, but significant improvement after treatment with MPA.
