LUNG - Bronchogenic carcinoma

There is a carcinoma arising from the bronchus to the left lower lobe which has extended to occupy much of the upper portion of the lobe. It has further invaded the mediastinal tissues with, close to its origin, compression of a vein. The discrete ovoid and rounded areas in which carbon pigment can be seen are lymph nodes involved by the tumour. On the reverse side of the specimen compression of the superior vena cava can be demonstrated.
