LUNG - Carcinoid tumour

This specimen is part of a lower lobe of lung. Pleural thickening is apparent. An ovoid circumscribed tan-coloured tumour 2cm in maximum diameter is obstructing the main bronchus. There is gross cylindrical bronchiectasis distal to the tumour, with abscess formation in some areas.
This woman presented at the age of 33 with right lower lobe pneumonia from which she recovered. 6 months later a similar episode occurred during which there was some blood-staining of the sputum. This led to bronchoscopy. Histology of the lesion is that of a bronchial carcinoid tumour.
