[Primary sarcoma of the pulmonary artery of the hemangioendotheliosarcoma type].
A case of primary sarcoma of the pulmonary artery presenting with the symptomatology of a bronchopulmonary tumour is studied in comparison with those reported up to the present in the literature. The tumour, examined in the pneumonectomy specimen, appeared to be inserted into the trunk of the left pulmonary artery with unusual propagation in the distal arteries. It had also spread into the neighbouring bronchial lumina. Histologically, the appearance was, rarely, that of a haemangioendotheliosarcoma. The histogenesis of these neoplasms is briefly discussed.
