Abstract: Objective To summarize the clinical features and the diagnosis-treatment points of sarcoidosis related pleural effusion.Methods Six typical sarcoidosis related pleural effusion cases with pathological evidence were reviewed,and the clinical data of these cases were retrospectively analyzed and the related literatures were reviewed.The literature review was carried out respectively with “sarcoidosis”,“pleural disease” and “pleural effusion” as the keywords in CNKI and PubMed database by January 2014.Results Six cases,including 1 male and 5 females,with sarcoidosis related pleural effusions were reported.3 cases had bilateral effusions,2 cases had left effusion and 1 case had right effusion.The pleural effusion routine test had a low specificity,which demonstrated that the fluid was exudate and consisted with large number of lymphocytes.3 of these cases were diagnosed by medical thoracoscopy.Medical thoracoscopy revealed that pleural involvement was variable with multiple nodulespresent in some cases and subtle change in others.A total of 28 literatures and 92 cases with pleural involvement in sarcoidosis were retrieved from CNKI and PubMed database (time range:2004.1-2014.1),including 59 cases of pleural effusion,29 cases of pleural thickening,3 cases of pneumothorax and 1 case of nodules in pleura.Conclusions Pleural involvement in sarcoidosis was often misdiagnosed or mistreated as tuberculous pleurisy because the routine tests regarding pleural effusion usually had a low specificity.Medical thoracoscopy could provide clinicians with important clues to assist differentiation of the cause for non-conclusive pleural effusion in this situation.
