Summary
Esophageal tuberculosis is rare but presents with distinct endoscopic signs. Deep ulcers, tracheoesophageal fistula, and nonhealing ulcers suggest this rare form of tuberculosis.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Pulmonology
Background:
- Esophageal tuberculosis (TB) is an uncommon condition with varied, nonspecific clinical and endoscopic presentations.
- Its symptoms can mimic esophageal cancer and deep fungal infections, complicating diagnosis.
- Limited data exists on the specific endoscopic findings associated with esophageal TB.
Observation:
- A retrospective review identified four cases of esophageal TB over a five-year period.
- Common presenting symptoms included dysphagia and weight loss.
- Notable endoscopic findings were deep, large proximal esophageal ulcers, tracheo-esophageal fistula, and nonhealing ulcers.
Findings:
- Deep and large proximal esophageal ulcers were observed in two patients.
- Tracheo-esophageal fistula was identified in one patient.
- A nonhealing proximal esophageal ulcer was noted in another patient.
Implications:
- Specific endoscopic features like deep ulcers, tracheoesophageal fistula, and nonhealing ulcers are highly suggestive of esophageal TB.
- Early recognition of these endoscopic signs can aid in the timely diagnosis of this rare condition.
- Distinguishing esophageal TB from malignancy or fungal infections is crucial for appropriate management.
