Esophageal tuberculosis (ET) is an extremely rare disease and herein, we present an ET case. Endoscopic findings of ET are variable and diverse and can be easily mistaken for malignancy. A definitive diagnosis of ET is difficult to make with white light endoscopy alone, and the diagnostic yield of a biopsy is low in secondary ET cases with normal overlying mucosa. Although the findings of conventional endoscopy and endoscopic ultrasonography in ET have been reported so far, few reports have described the findings of magnifying endoscopy with narrow-band imaging (ME-NBI). Dilated microvessels without irregularities on ME-NBI may be useful to differentiate secondary ET from esophageal carcinoma, since the findings suggest compression from the depth. Although rare, ET has to be considered in the differential diagnosis for any unexplained esophageal lesions.
