| Abstract |
|
Acute fibrinous and organizing pneumonia (AFOP) is a histological pattern consisting of intra-alveolar fibrin in the form of fibrin “balls” and organizing pneumonia, without hyaline membranes or prominent eosinophil infiltration. Some reports suggest that the clinical course and pathological findings of AFOP are different from typical findings of bronchiolitis obliterans organizing pneumonia (BOOP) or eosinophilic pneumonia (EP), and its prognosis can be better or similar to that of diffuse alveolar damage (DAD). We report two cases of pathologically demonstrated AFOP experienced recently at our institute. One fatal case revealed a rapid development of respiratory failure and the need for mechanical ventilation. Another nonfatal case revealed subacute diffuse bilateral lung infiltration without the need for mechanical ventilation. Judging from our experience, the patient who required a mechanical ventilator had a poorer prognosis than the one who did not need a mechanical ventilator. |
