In this article, We are going to discuss bronchial adenoma regarding its definition, clinical picture, diagnostic investigations and methods of management .
Bronchial adenoma considered to be a locally malignant or a locally invasive tumour.
(female = male)
1- Cough and recurrent haemoptysis (the tumour is highly vascular) .
2- Bronchial obstruction with recurrent pulmonary infections, lung collapse may occur .
3- Carcinoid syndrome :
attacks of Bronchospasm , Flushing , Diarrhea
• Bronchoscopy : Biopsy (bleeding should be anticipated)
• HIAA : Hydroxy Indole Acetic Acid in urine = metabolite of serotonine
• Local removal of the tumour tissue from the bronchial lumen (bronchotomy with local excision), laser therapy may be needed.
• Chemotherapy, radiotherapy also can be used.
What is Bronchial adenoma ?
It is a slowly growing intrabronchial lesions that represent 50% of all benign pulmonary neoplasm 80-90% are carcinoids, 10-15% are adenocystic and 2-3% are mucoepidermoid.Bronchial adenoma considered to be a locally malignant or a locally invasive tumour.
What are the manifestations of Bronchial adenoma ?
Clinical picture(female = male)

2- Bronchial obstruction with recurrent pulmonary infections, lung collapse may occur .
3- Carcinoid syndrome :

Investingations
• X-ray : Coin shadow
• Bronchoscopy : Biopsy (bleeding should be anticipated)
• HIAA : Hydroxy Indole Acetic Acid in urine = metabolite of serotonine
Treatment of Bronchial adenoma :
• Surgical Resection of the lobe or the segment that contain the tumour.• Local removal of the tumour tissue from the bronchial lumen (bronchotomy with local excision), laser therapy may be needed.
• Chemotherapy, radiotherapy also can be used.
