BRONCHIAL CARCINOID TUMOUR

BRONCHIAL CARCINOID TUMOUR

Clinical History

This specimen was removed from a 40 year old man who had recurrent episodes of lower lobe pneumonia for six months. In between these episodes he had noticed some haemoptysis.

Pathology

The specimen is a lower lobe sliced longitudinally to display the cut surface. Adjacent to, and probably arising from, the lower lobe bronchus is an ovoid encapsulated tumour 3 cm in largest diameter. The cut surface shows dense, light brown tissue with some haemorrhagic staining. There is no apparent infiltration of surrounding lung parenchyma. The adjacent bronchus is compressed. The lung tissue is otherwise normal. Histological examination revealed a carcinoid tumour.

Note

Carcinoid tumours of lung rarely produce vasoactive amines, unlike carcinoids arising in the small bowel.
