INTRODUCTION Young's syndrome (YS) is a rare, inherited syndrome commonly seen in middle-aged men with chronic rhinosinusitis, nasal polyps, decreased fertility due to azoospermia, and bronchiectasis. In this paper, we present a case of YS of unknown cause together with a literature review. CASE PRESENTATION A 28-year-old male patient with the complaints of cough, sputum, recurrent nasal congestion, and shortness of breath lasting for more than ten years, was admitted to our clinic after bronchiectasis was observed in the thoracic computed tomography. CONCLUSIONS An accurate diagnosis of YS is usually made late, which reduces patients' quality of life and leads to chronic respiratory problems. Failure to diagnose this disease may expose the patient to unnecessary and repeated hospitalizations and examinations, and result in treatment failure.
