Journal of Medical Case Reports 2011 5 447 http www.jmedicalcasereports.eom content 5 1 447 JOURNAL OF MEDICAL CASE REPORTS CASE REPORT Open Access Dysphagia as a manifestation of esophageal tuberculosis a report of two cases Joana Gomes Ana Antunes Aurora Carvalho and Raquel Duarte Abstract Introduction Esophageal involvement by Mycobacterium tuberculosis is rare and the diagnosis is frequently made by means of an esophageal biopsy during the evaluation of dysphagia. There are few cases reported in the literature. Case presentation We present two cases of esophageal tuberculosis in 85- and 65-year-old male Caucasian patients with initial complaints of dysphagia and epigastric pain. Upper gastrointestinal endoscopy resulted in the diagnosis of esophageal tuberculosis following the biopsy of lesions of irregular mucosa in one case and a sessile polyp in the other. Pulmonary tuberculosis was detected in one patient. In one patient esophageal stricture developed as a complication. Antituberculous therapy was curative in both patients. Conclusion Although rare esophageal tuberculosis has to be kept in mind in the differential diagnosis of dysphagia. Pulmonary involvement has important implications for contact screening. Introduction Tuberculosis of the esophagus is a rare condition even in countries with a high incidence of tuberculosis TB 1 2 and studies estimate that it constitutes about 0.3 of gastrointestinal TB cases 3 . Involvement of the gastrointestinal tract occurs through ingestion of infected sputum or hematogenous spread from primary pulmonary TB 4 . Most cases of esophageal tuberculosis are secondary to direct extension from adjacent structures such as mediastinal lymph nodes or pulmonary sites. Primary esophageal tuberculosis is even rarer 5 . Esophagic involvement by tuberculosis usually affects the middle third of the esophagus at the carina level 6 . The most common symptoms are dysphagia or retrosternal pain but odynophagia and weight .
