Les localisations naso-sinusiennes de la sarcoïdose

This case report underlines the difficulty to diagnose sinonasal sarcoidosis. When a patient is treated for sarcoidosis, sinonasal localization of the disease must be suggested in the event of chronic rhinosinusitis. On the other hand, sarcoidosis must be suggested and specific complementary examination must be performed in the event of chronic rhinosinusitis without improvement under usual treatment. ENT biopsy remains the main argument for diagnosis.
