Gastrointestinal tuberculosis is a relatively common form of extrapulmonary tuberculosis. Primary esophageal tuberculosis is rare and frequently misdiagnosed or delayed in diagnosis by clinicians. Four cases of primary esophageal tuberculosis are reported. All patients involved underwent pathological examination of their esophageal lesions, which revealed granulomas. Additionally, molecular detection confirmed the presence of Mycobacterium tuberculosis DNA in two cases. All patients received antituberculosis therapy and achieved good outcomes.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
