Application of medical thoracoscopy in diagnosis of sarcoidosis-related pleural effusion.

Pleural effusion caused by sarcoidosis is unusual. Medical thoracoscopy could help clinicians detect associated pleural disease, yet studies on thoracoscopic observations in sarcoidosis pleural involvement are rare. In this article, we report the utility of medical thoracoscopy in diagnosing sarcoid-related pleural disease for three patients. Pleural nodularity was common with solitary and multiple nodules evident; biopsies confirmed the presence of diagnostic noncaseating granulomas.
