[Vascular tumors of the lungs].

Abstract

A series of nine vascular tumors of the lungs, five of them being benign hemangiomas, three hemangiosarcomas and one hemangiopericytoma is presented. In five patients the disease was detected on the basis of subjective complaints which indicated necessary hospitalization, in the other four patients the tumours were revealed by chance during preventive X-ray examination or X-ray examination for other causes. These patients were admitted to hospital for progression of lung changes. Five of the patients underwent surgery, lobectomy, was made in two cases, the other patients were treated by segmental, V-shape or atypical lung resection. Patients with benign hemangiomas manifested the best prognosis even in those where surgery was not possible. In cases of hemangiosarcoma or hemangiopericytoma the outlook is exceptionally serious even in primary forms. In the preoperation diagnostics of arteriovenous hemangiomas the tomographic examination and lung angiography represents an important help, in the other vascular tumours it is particularly CT and lung biopsy.
