[Manifestations of sarcoidosis in the upper respiratory tract].

Sarcoidosis is a multisystemic disease having unknown cause, characterized by non-caseating granulomatous inflammation of the organs involved. It predominantly affects the respiratory tract, with preference for the lower tract and less frequently affects the upper respiratory tract (nose, paranasal sinuses and larynx). It manifests non-specifically, with symptoms secondary to the obstruction of the airway. It can be confused with other more common disorders in our setting, such as tuberculosis. We conduct a review, fundamentally focusing on the diagnosis and treatment due to their difficulty.
