A Rare Cause of Esophageal Dysphagia - Secondary Esophageal Tuberculosis.

Tuberculosis (TB) is an infectious disease caused by . It continues to be one of the most common causes of death in adults across all countries. It is found to be relatively lower in North America. When aerosol droplets that contain are inhaled, it can deposit in the respiratory tract, particularly in the patient's lungs. Following this deposition, one of the four outcomes can take place. These include clearance of the organism immediately, primary disease, latent infection, and reactivation disease. Unhindered bacterial growth after primary infection can lead to a hematogenous spread of bacilli to produce disseminated TB. Esophageal involvement causing esophageal TB can be primary or secondary esophageal TB. We present a unique case of secondary esophageal TB with symptoms of dysphagia and odynophagia with primary TB focus on the lung. Computed tomography (CT) of the chest noted diffuse bilateral miliary lung disease. TB QuantiFERON gold and sputum culture were positive for TB. Mycobacterial culture for identification with high-performance liquid chromatography showed isoniazid-resistant TB. The patient was started on antitubercular therapy with rifampin, ethambutol, moxifloxacin, and pyrazinamide for a total of nine months. Esophagogastroduodenoscopy (EGD) reported severe ulcerations of the oropharynx and focal ulceration in the proximal to the mid esophagus. Histopathology revealed active ulcerative and granulomatous esophagitis with mycobacterial organisms. After EGD she was started on a full liquid diet and advanced as tolerated. After discharge, she followed with the Health Department and had three negative sputum cultures after the completion of therapy.
