The evolution can be acute, with a high rate of spontaneous remission, or chronic evolution, with specific organic manifestations. It affects the upper respiratory tract, of which laryngeal and nasal involvement are the most common. Laryngeal involvement is most often expressed by dysphonia, dyspnea and chronic cough, which are potentially common symptoms of respiratory failure. it mainly affects the supraglottic region, the diagnosis is based on clinical Biological and radiological findings and supported by histology, which shows noncaseous granulomas. Early diagnosis and adequate treatment are important to prevent airway obstruction, and the use of a tracheotomy. The treatment is based on systemic corticosteroids, immunosuppressants, intra-lesional steroid injection, radiotherapy, CO 2 laser or surgical excision. The evolution of sarcoidosis is unpredictable. It is characterized by relapses and remissions.
