Abstract

Tuberculosis remains a serious infectious disease with primary features of pulmonary manifestation in Korea. However, duodenal tuberculosis is rare in gastrointestinal cases of extrapulmonary tuberculosis. Here, we report a case of primary duodenal tuberculosis mistaken as a malignant tumor and diagnosed with QuantiFERON-TB GOLD (Cellestis Ltd.) in an immunocompetent male patient.

  Fig. 1 Initial gastroduodenoscopy. An ulcerohypertrophic mass is noted at the duodenal second portion below the ampulla of Vater.

• 

  Fig. 2 Abdomen computed tomography. (A, B) The initial scan shows an ulcerohypertrophic lesion in the duodenal second to third portion (black arrow) and mass-like, multiple perilesional enlarged lymph nodes with some necrotic changes (white arrow). (C, D) After antituberculosis treatment for 6 months, the duodenal lesion (black arrow) and multiple lymph nodes (white arrow) were decreased.

• 

  Fig. 3 Histopathological examination shows granulomatous inflammation with necrosis (H&E stain, ×400).

• 

  Fig. 4 Transparent capped endoscopy shows a scared lesion with central depression and peripheral reepithelization at 1 month after treatment.
