title: [Chronic cryptogenic pneumonia].
abstract: We report a case of a 72 year old man with the appropriate criteria for the recently identified chronic cryptogenic pneumonia: dyspnoea, cough, low general state, fever, raised sedimentation rate, localised opacities on the chest x-ray; no cause has been identified; the patient will improve on steroid therapy even though antibiotics are without effect, but relapses on stopping the steroids. A lung biopsy shows a predominant intra-alveolar fibrosis. A definitive cure can be obtained by 12 weeks of steroid therapy.
