All of the following are features of non-specific interstitial pneumonia (NSIP), except:
Non-specific interstitial pneumonia (NSIP): The cellular pattern consists primarily of mild to moderate chronic interstitial inflammation, containing lymphocytes and a few plasma cells. The fibrosing pattern consists of diffuse or patchy interstitial fibrotic lesions of roughly the same stage of development, an impoant distinction from UIP (usual interstitial pneumonia). Fibroblastic foci, honeycombing, hyaline membranes and granulomas are absent. Has much better prognosis than idiopathic pulmonary fibrosis
