BackgroundIn the presence of a compatible clinical picture, the diagnosis of sarcoidosis requires pathologic confirmation of noncaseating epithelioid granuloma in affected tissues. The standard procedure of choice for most patients is a bronchoscopy with transbronchial biopsy (TBB), which has a diagnostic yield of 40% to 90%. The lowest yield with TBB is in cases that present with predominant mediastinal or intra-abdominal lymphadenopathy (LN) and minimal parenchymal lung involvement.ObjectiveTo study the diagnostic yield of EUS-guided FNA in diagnosing sarcoidosis with predominant LN or masses.DesignRetrospective chart review.SettingTeaching university hospital.PatientsAnalysis of 21 consecutive patients with sarcoidosis and predominant mediastinal and/or intra-abdominal LN or masses who underwent EUS-guided FNA.ResultsEUS-guided FNA diagnosed sarcoidosis in 18 of 21 patients (86%). In 3 patients, EUS-guided FNA was either not diagnostic or inconclusive, and patients underwent mediastinoscopy with lymphadenectomy, which established the diagnosis of sarcoidosis. Seven of the 21 patients (33%) had intra-abdominal LN and/or masses, and EUS-guided FNA of the intra-abdominal pathology was diagnostic of sarcoidosis in 4 of the 7 patients (57%). Four of the 21 patients (19%) had a history of malignancy, and use of EUS-guided FNA helped in ruling out the recurrence of malignancy in 3 of the 4 patients (75%).LimitationsMycobacterial and fungal culture was not obtained in all patients.ConclusionsEUS-guided FNA offers a practical, minimally invasive technique for the diagnosis of sarcoidosis in patients who present with predominant mediastinal and/or intra-abdominal LN or masses.
