title: Cryptogenic organizing pneumonia with atypical histopathological features.
abstract: A case report of cryptogenic organizing pneumonia (COP); also known as bronchiolitis obliterans organizing pneumonia (BOOP) is presented. The histopathologic findings of COP are well documented in the literature and typically consist of organizing pneumonia of uniform appearance. This case report describes, in addition to the classic findings, more acute exudative inflammation not usually associated with this condition. Variation in the evolution of the pneumonic process is one of the reasons for reporting this case. The promotion of awareness of this treatable condition is the other reason for reporting this case. When multifocal areas of consolidation are demonstrated radiologically, particularly when peripheral and basal, and in the correct clinical setting, the possibility of COP should be entertained. This condition responds dramatically to steroid therapy, and has a good prognosis.
