esophageal tuberculosis

Esophageal tuberculosis is extremely rare in clinical practice. In 1837, Denonvilliers of France first reported a case of esophageal tuberculosis confirmed by autopsy. Subsequently, Torek (1931) reported the first case of primary esophageal tuberculosis. Since then, sporadic case reports of esophageal tuberculosis have continued to appear. Esophageal tuberculosis is divided into two types: primary and secondary. Primary esophageal tuberculosis refers to direct invasion of the esophageal mucosa by tubercle bacilli, with the tuberculous lesion mainly in the esophagus and no obvious tuberculous lesions elsewhere in the body. However, some authors believe that primary esophageal tuberculosis does not exist; secondary esophageal tuberculosis is often caused by direct or indirect invasion of the esophageal wall by tuberculosis of the periesophageal and mediastinal lymph nodes.
