Abstract:
Purpose. To introduce a minimally invasive procedure, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), to obtain a pathologic evidence of a definite ocular sarcoidosis in a patient who initially presented with presumed ocular sarcoidosis with pulmonary involvement. Methods. An EBUS-TBNA procedure was performed at perihilar lymph nodes, subcarina, and right paratrachea of the patient and specimen obtained was sent for histocytopathological studies. Result. Histocytopathological findings revealed aggregates of epithelioid histiocytes forming a noncaseous granuloma, a hallmark of sarcoidosis. Conclusion. EBUS-TBNA should be considered an alternative procedure to provide cytohistopathology proven diagnosis of definite ocular sarcoidosis.
