Esophageal tuberculosis

Esophageal tuberculosis is extremely rare in the clinic. French Denonvilliers first reported a case of esophageal tuberculosis confirmed by autopsy in 1837. Later, Torek (1931) reported the first case of primary tuberculosis of the esophagus. Cases of esophageal tuberculosis have been reported since then. There are two types of esophageal tuberculosis: primary and secondary. Primary esophageal tuberculosis refers to Mycobacterium tubemulosis that directly invades the esophageal mucosa. Tuberculosis is mainly esophageal tuberculosis, and there are no obvious tuberculosis lesions in other parts of the body. But some authors believe that there is no primary esophageal tuberculosis; secondary esophageal tuberculosis is often caused by direct or indirect invasion of the esophageal wall around the esophagus and mediastinal lymph node tuberculosis.
