Abstract

Acute fibrinous and organizing pneumonia (AFOP) is a histological pattern consisting of prominent intra-alveolar fibrin and organizing pneumonia, with out hyaline membranes or prominent eosinophilia. The clinical manifestations of AFOP resemble those of acute lung injury such as acute interstitial pneumonia (AIP). However, the classic histological patterns of AFOP differ from diffuse alveolar damage (DAD), bronchiolitis obliterans with organizing pneumonia (BOOP) or acute eosinophilic pneumonia (AEP). The characteristic intra-alveolar fibrin ball and lack of classic hyaline membrane are the predominant histological features of AFOP. Although some reports suggest that its clinical course is less catastrophic than DAD, the clinical entity that distinguishes AFOP from DAD has not been established. We present a case of pathologically demonstrated AFOP in a 79-year-old man. The radiological findings of our case were similar to those of DAD, presented with diffuse bilateral lung infiltrations. However, despite the rapid development of respiratory failure, the patient had a better response and outcome to steroid therapy than what would be expected for DAD.

급성 섬유소성 기질화 폐렴 (AFOP)은 임상적으로 급성 간질성 폐렴과 유사하지만 세기관지내 섬유소 축적을 보이며 유리질막이 존재하지 않는 조직학적 특성을 갖는 간질성 폐렴의 한 형태이다. 일부 보고나 본 증례에 따르면 임상경과는 급성 간질성 폐렴보다 비교적 양호한 것으로 기대된다. 그러므로 급격히 진행하는 호흡곤란을 호소하는 환자에게 거친 호흡음과 함께 수포음이 들리고, 방사선 검사상 양측 폐 전반에 걸쳐 현저한 간유리 음영이 있을 경우 조직소견을 바탕으로 급성 간질성 폐렴이나 다른 간질성 폐질환을 감별진단하고 치료방법을 결정하고 병의 경과 및 예후를 예측할 수 있다.
