3-dimensional reconstruction (computed tomography) of the lesion, with a narrowed right intermediate bronchus as a result of compression by the lesion.

A cystic lesion of 5 cm was surgically removed by video-assisted thoracic surgery.
- Figure 6
Histology of the resected cyst. Cyst lined by respiratory type epithelium (haematoxylin and eosin staining, scale bar = 200 µm). a) The epithelium is characterised by pseudostratified columnar and ciliated cells (haematoxylin and eosin staining, scale bar = 50 µm). b) Seromucous glands are located in the underlying fibrotic cyst wall (haematoxylin and eosin staining, scale bar = 50 µm). c) Positive cytoplasmic staining for an epithelial marker (CK AE1/AE3-immunostaining 40x magnification) and d) positive nuclear staining for a pulmonary/bronchial marker (TTF1 immunostaining, 40x magnification). e) Positive cytoplasmic staining for an epithelial marker (CK AE1/AE3-immunostaining, 40x magnification) and f) positive nuclear staining for a pulmonary/bronchial marker (TTF1 immunostaining, 40x magnification).
