Primary ciliary dyskinesia (PCD) can manifest with bronchiolitis, a lung inflammation. This case highlights follicular bronchiolitis in PCD, suggesting rarer presentations warrant further research.
Area of Science:
- Pulmonary Medicine
- Genetics
- Rare Diseases
Background:
- Primary ciliary dyskinesia (PCD) is a genetic disorder characterized by impaired ciliary function.
- Ciliary dysfunction is known to be associated with various respiratory conditions, including bronchiolitis.
- Kartagener's syndrome, a subtype of PCD, has previously been linked to diffuse bronchiolitis in some populations.
Observation:
- This report details a case of primary ciliary dyskinesia (PCD) presenting with follicular bronchiolitis (FB).
- The patient experienced recurrent symptoms of cough, dyspnea (shortness of breath), and bronchiectasis (airway widening).
Findings:
- Follicular bronchiolitis represents a less common manifestation of primary ciliary dyskinesia.
- The co-occurrence of PCD and FB suggests a potential link between specific ciliary defects and this inflammatory airway pattern.
Implications:
- This case broadens the clinical spectrum of primary ciliary dyskinesia (PCD).
- It encourages further investigation into rarer variants and atypical presentations of PCD.
- Understanding these diverse manifestations is crucial for accurate diagnosis and management of PCD patients.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
