- Two regions where pseudostratified ciliated columnar epithelium is found: trachea; bronchi (Aponeurosis — Histology Question Bank)
- A condition of the lung characterised by a productive cough, preceded by long term cigarette smoking and histologically by enlargement of the mucus secreting glands of the trachea and bronchi leading clinically to a dyspnoeic patient presenting with cyanosis ('blue bloater'): (Medical MCQs: Chemical Pathology & Haematology Exam Review)

Practice questions on Bronchi
A previously healthy 5-year-old girl has fever, expiratory wheezes, and suddenly worsening dyspnea. WBC is 14,480. Emergency bronchoscopy reveals bronchi plugged by exudates. Most likely organism?
- Bacteroides fragilis
- Candida albicans
- Haemophilus influenzae
- Mycobacterium tuberculosis
Answer: C. High WBC + bronchi plugged by fibrin-rich neutrophilic exudates in a child after descending laryngotracheobronchitis = Haemophilus influenzae. Can cause bronchopneumonia with airway obstruction. ---
A 41-year-old woman has episodic dyspnea with expiratory wheezes, elevated serum IgE, peripheral eosinophilia, sputum eosinophils, perihilar bronchiectasis on CXR, and detectable serum galactomannan. Most likely pathologic finding in her bronchi?
- ANCA-associated vasculitis
- Blastomycosis
- Invasive candidiasis
- Non-invasive aspergillosis
Answer: D. Elevated IgE + eosinophilia + galactomannan (Aspergillus cell wall component) + bronchiectasis + asthma exacerbations = allergic bronchopulmonary aspergillosis (ABPA). The fungus colonizes bronchi non-invasively. ---
