Sarcoidosis presented as retroperitoneal and lung mass.

Sarcoidosis is a multisystem granulomatous disorder of unknown aetiology characterised pathologically by the presence of non-caseating granulomas in involved organs. Sarcoidosis most frequently involves the lungs followed by eye and skin. Presentation as retroperitoneal and lung mass is rare in sarcoidosis. We describe an unusual case of sarcoidosis where the patient presented with large retroperitoneal and lung masses, and was treated as tuberculosis. 2015 BMJ Publishing Group Ltd.
