[An unusual cause of dysphagia: esophageal tuberculosis]

Esophageal tuberculosis is a rare etiology of dysphagia. Such a location is also rare in comparison with other digestive tract sites of the disease (3.2%). Esophageal involvement may be secondary or primary. Diagnosis is particularly difficult in the latter situation. At any event, the diagnosis can only be histological by examination of endoscopic biopsy material. Treatment is essentially medical and leads to recovery in most patients.
