Esophageal tuberculosis
Esophageal tuberculosis is extremely rare in clinical practice. In 1837, Denonvilliers in France first reported a case of esophageal tuberculosis confirmed by autopsy. Later, Torek (1931) reported the first case of primary esophageal tuberculosis. Since then, there have been reports of esophageal tuberculosis cases. Esophageal tuberculosis is divided into two types: primary and secondary. Primary esophageal tuberculosis refers to the direct invasion of the esophageal mucosa by Mycobacterium tubemulosis. The tuberculosis lesions are mainly esophageal tuberculosis, and there are no obvious tuberculosis lesions in other parts of 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.
