Abstract
Tumors of 0.5 mm in diameter can be recognized by careful examination of the cut section of the lungs. They may be situated along the bronchi or be randomly distributed all over the lung parenchyma. There is a tendency of tumors to flow together and in some cases a whole lobe may be involved. Small nodules are usually well demarcated, fleshy, and firm and the appearance of their cut surface depends on tumor type. Pure squamous cell tumors are often grayish white and granular on the cut surface. Larger tumors may be cystic or may undergo central necroses. In mixed squamous-adenocarcinomas a viscous fluid may be wiped from the cut surface.
