Primary ciliary dyskinesia.

Primary ciliary dyskinesia (PCD) is a rare genetic condition that affects the ciliary function of the respiratory tract, sperm tail, cilia of the embryonic node, and fallopian tube. The condition is characterized by impaired ciliary action, leading to recurrent lower-respiratory-tract infections, bronchiectasis, rhino-sinusitis, otitis media, impaired fertility in women, and infertility in men.1 Early diagnosis is important to prevent disease progression.2 Examination of nasal or bronchial biopsy specimens by electron microscopy is the definitive diagnostic test. We present a 36-year-old woman with a history of recurrent lower-respiratory-tract infections and bronchiectasis. She was diagnosed with PCD, based on clinical presentation and electron microscopy of bronchial biopsy.
