title: [Diagnostic difficulties in angiosarcoma of the pulmonary artery with hemoptysis].
abstract: Intimal sarcomas growing from the pulmonary trunk or branches of the pulmonary artery, are rare tumours in which the diagnosis is most often made at autopsy or during a thoracotomy. Usually the clinical pictures is non specific resembling a severe pulmonary embolus which is resistant of all treatment. With the help of new imaging techniques, a pre-operative diagnosis is made in more than half the cases. When there is a tumour which is relatively localised and without endoluminal invasion, as in the observation reported here, the diagnosis rests on the histology from the operative specimen.
