Sarcoidosis is a systemic disease mainly affecting the mediastinum and the lungs. The other manifestations are much rarer and lead to diagnostic and therapeutic wanderings. The present study reports a case of lymph node sarcoidosis revealed by a long-lasting fever. The diagnosis is based on clinical and paraclinical arguments and the elimination of other causes of lymphadenopathy. The evolution is favorable after 6 months of corticosteroid therapy.
