Abstract
Malignant vascular tumours are rarely seen and angiosarcoma which is the most common tumour in this group making less than 2% of all sarcomas. Angiosarcoma which frequently occurs in the heart, pericardium, breast, liver, skin, bone and soft tissues is rarely located in the lung and (if so) is usually metastatic. Primary pulmonary angiosarcoma originated from bronchial or pulmonary arteries has been reported in about 10 cases. This case, diagnosed as "nonsmall cell carcinoma" by endobronchial biopsy and found to be operable, was diagnosed as "primary pulmonary angiosarcoma" after the histopathological and immunohistochemical examination of pneumonectomy materials and organ screening.
Özet
Malign vasküler tümörler nadir görülmekte ve bu grupta en yaygın olan anjiyosarkom, tüm sarkomaların %2'sinden daha azını oluşturmaktadır. En sık kalp, perikard, meme, karaciğer, deri, kemik ve yumuşak dokularda oluşan anjiyosarkom, nadiren akciğerlerde yerleşir ve sıklıkla metastatiktir. Bronşiyal veya pulmoner arterlerden köken alan primer akciğer anjiyosarkomu, 10 kadar olguda bildirilmiştir. Bronkoskopik biyopsiyle "küçük hücreli dışı akciğer karsinomu'' tanısı konulan ve operabl bulunan bir olgu, pnömonektomi materyalinin histopatolojik ve immünohistokimyasal incelemesi ve diğer organ taramaları sonucu "primer akciğer anjiyosarkomu'' olarak değerlendirilmiştir.
