| bronchogenic carcinoma | <tumour> Squamous cell or oat cell carcinoma that arises in the mucosa of the large bronchi and produces a persistent productive cough or haemoptysis; local growth causes bronchial obstruction and is observed radiologically as an enlarging lung mass; malignant tumour cells can be detected in the sputum, and they metastasize early to the thoracic lymph nodes and to the brain, adrenal glands, and other organs via the bloodstream.

| bronchogenic cyst | <radiology> Abnormality of primitive foregut (ventral segment = tracheobronchial tree; dorsal segment = oesophagus), lined with columnar respiratory epithelium, CT: water density (50%); higher density (50%); may have air/fluid level, mediastinal brochogenic cyst (86%), associated with spinal abnormalities, M:F = 1:1, stridor, dysphagia; usually assymptomatic, may communicate with tracheal lumen, location: posterior mediastinum (50%), pericarinal (35%), superior mediastinum (14%); usually on right, intrapulmonary bronchogenic cyst (14%), M>F; LL:UL = 2:1 (usually medial third), infection (75%), dyspnea, haemoptysis, 36% will eventually contain air (12 Dec 1998) |
| carcinoma, bronchogenic | A cancer of the lung, so-called because it arises from the epithelium of the bronchial tree. It is not a histologic designation despite the name. (12 Dec 1998) |
