title: [Bronchioalveolar carcinoma].
abstract: A study of 21 patients suffering from bronchioalveolar carcinoma and 1028 comparable cases of the literature is presented. By this we gained statistical data concerning radiological and clinical manifestations of this rare tumour. However, radiological signs estimated to be typical of this carcinoma, like "rabbit ear sign" and positive "air bronchogram" are too rare to be really helpful for putting up the diagnosis. At time of diagnosis the mean age was 58 years. Men are hardly more frequently concerned than women. Smoking seems to have no aetiological significance. The most common clinical symptom was chronic cough followed by chest pain. A large amount of sputum--a symptom which sometimes has been estimated to be typical of this tumour--occurred only very rarely.
