Rare involvement of paranasal sinuses in sarcoidosis: case report and literature review

Sarcoidosis is a non-caseating inflammatory chronic systemic disease of unknown etiology, which may affect one or more organs. Paranasal sinuses involvement occurs sporadic in sarcoidosis. We report a patient with a medical history of sarcoidosis involving her lungs, liver, and lymphatic system for four years who now presented with nasal and sinuses symptoms. The primary treatment with local cortisone showed no improvement. Computed tomography (CT) scan of the paranasal sinuses (PNS) revealed signs of chronic pansinusitis. She was successfully treated with endoscopic sinonasal surgery. Subsequent histological analysis confirmed the involvement of the PNS with sarcoidosis. Her follow-up during the last 6 months was without recurrence
