Focus on Sarcoidosis
- Diagnosis of extra-pulmonary sarcoidosis can be difficult, and a biopsy is usually required. We evaluated the utility of endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) in patients with suspected extra-pulmonary sarcoidosis with thoracic lymph nodes ≤10 mm on chest computed tomography (CT) and no or minimal pulmonary infiltrates.
- The prevalence and incidence of sarcoidosis, a granulomatous disorder involving multiple organ systems, varies among geographical regions and ethnicities. This study evaluated the incidence, prevalence, and mortality of sarcoidosis in a large nationwide population-based cohort in Korea.
