LUNG - Carcinoma

The specimen consists of a portion of the right lower lobe, and shows a lobular yellowish mass arising from a bronchus, probably the medial basal bronchus. The lesion shows areas of necrosis and the tumour extends to the pleural surface, which is distorted. This is a peripherally-situated tumour suggesting the possibility of bronchogenic adenocarcinoma, however histology is required to determine tumour type.
