Cryptogenic Organizing Pneumonia
Type of disease: Rare conditions
Cryptogenic organizing pneumonia (COP) is a rapidly developing inflammatory lung disease characterized by flu-like symptoms, including cough, fever, malaise, fatigue, and weight loss. COP often affects adults in midlife (40 to 60 years of age). No predisposing factors have been identified and the cause is often unknown. Diagnosis may be made through computed tomography (CT) scan or lung biopsy. Response to treatment with corticosteroids is generally favorable.
