PCP remains the leading cause of deaths in patients with AIDS. As familiarity with PCP increases, atypical manifestations of the diseases are being recognized with greater frequency. There are following "atypical" manifestations of PCP ; 1) interstitial lung response that include diffuse alveolar damage, bronchiolitis obliterance, interstitial fibrosis, and lymphoplasmocytic infiltrate 2) striking localized process frequently exhibiting granulomatous features 3) extensive necrosis & cavitation 4) extrapulmonary dissemination of the disease. A wide variety of pathologic manifestations may occur in PCP in human immunodeficiency virus-infected patienst and that atypical features should be sought in lung biopsies from patients at risk for PCP. We had experienced a case of PCP, which presented with severe hypoxia, progressive dyspnea and fine crackles. It was diagnosed as PCP in AIDS with manifestation of BOOP by open lung biopsy and showed good response to Bactrim & corticosteroid therapy.

Bronchiolitis obliterans organizing pneumonia(BOOP) is a pathologic entity characterized by the formation of plugs of fibrous tissue in bronchioles and alveolar ducts. It clad been described in association with several connective tissue diseases, i.e. systemic lupus erythematosus, Behcet's disease, polymyositis-dermatomyositis, polymyalgia rheumatica and Sjogren's syndrome. Recently, there were few additional reports on BOOP, anteceded by rheumatoid arthritis. We clad experienced a case of 60 years old female patient who clad been admitted for acute respiratory difficulty and abnormal chest roentgenographic findings. She was diagnosed as having rhematoid arthritis 20 years ago. On the course of our treatment, she did not respond to antibiotics. Moreover, no microorganism grew in the sputum and blood. Thus, the bronchoscopic biopsy was done. The patient showed a dramatic response to steroid therapy, and the pathologic bindings of the bronchoscopic biopsy confirmed as BOOP. To our knowledge, this is the first reported case of BOOP anteceded by rheumatoid arthritis in Korea.
