Although the overall incidence of tuberculosis in underdeveloped areas has increased in recent years, esophageal tuberculosis (ET) is still rare. Intestinal tuberculosis (ITB) is relatively more common, but there are few reports of ET complicated with ITB. We report a case of secondary ET complicated with ITB in a previously healthy patient.
A 27-year-old female was hospitalized for progressive dysphagia, retrosternal pain, acid regurgitation, belching, heartburn, and nausea. Upper gastrointestinal endoscopy showed a mid-esophageal ulcerative hyperplastic lesion. Endoscopic ultrasonography showed a homogeneous hypoechoic lesion, with adjacent enlarged lymph nodes. Biopsy histopathology showed inflammatory exudation, exfoliated epithelial cells and interstitial granulation tissue proliferation. Colonoscopy revealed a rat-bite ulcer in the terminal ileum and a superficial ulcer in the ascending colon, near the ileocecal region. The ileum lesion biopsy showed focal granulomas with caseous necrosis. Polymerase chain reaction for Mycobacterium tuberculosis was positive in the esophageal and ileum lesion biopsies. The T-cell spot tuberculosis test was also positive. The patient was diagnosed with secondary ET infiltrated by mediastinal lymphadenopathy and complicated with ITB, possibly from the Mycobacterium tuberculosis-infected esophageal lesion. After 2 mo of anti-tuberculosis therapy, her symptoms improved significantly, and upper gastrointestinal endoscopy showed healing ulcers.
When dysphagia or odynophagia occurs in patients at high-risk for tuberculosis, ET should be considered.
Core tip: Esophageal (ET) and intestinal tuberculosis are rare forms of tuberculosis, and there are few reports of ET complicated with intestinal tuberculosis. Our patient presented with progressive dysphagia, but no other significant medical history. Lesions in the esophagus and colon were found to be Mycobacterium tuberculosis positive. The patient responded well to anti-tuberculosis therapy. This case demonstrates that ET should be suspected when patients at high risk for tuberculosis present with dysphagia or odynophagia.
