A rare presentation of sarcoidosis as a polypoid endobronchial structure

Sarcoidosis is a multisystem disease of unknown etiology that predominantly affects intrathoracic lymph nodes and lungs. Although the diagnosis of sarcoidosis in some cases may be established on the ground of the clinical and radiological pattern, the American Thoracic Society in the 1999 statement emphasized that the diagnosis of sarcoidosis requires “histological demonstration of no necrotizing granulomas” [Hunninghake GU, Costabel U, Ando M et al. Statement on sarcoidosis. Am J Respir Crit Care Med 1999; 160: 736–55]. We present the case of a very rare presentation of sarcoidosis as a polypoid endobronchial lesion coexisting with lymph node involvement. Diagnostics of sarcoidosis was confirmed in the histological examination of the specimens both from the lymph node and the polypoid lesion.
