Tuberculosis of the Stomach Mimicking Gastric Submucosal Tumor: Diagnosis by Endoscopic Ultrasound.

INTRODUCTION

Gastrointestinal tuberculosis (TB), specifically gastric TB, is a rare form of extrapulmonary TB. Diagnosis proves challenging with nonspecific signs and symptoms. In this case report, a 22-year-old male came in with complaints of recurrent hematemesis and melena.

CASE PRESENTATION

We found a submucosal mass with ulceration in the stomach cardia on esophagoduodenoscopy (EGD). The endoscopic ultrasound (EUS) finding was a hypoechoic submucosal lesion with a clear margin; specimens were taken using fine needle aspiration (FNA) for further histopathological examination. The result indicated granuloma of in pathology, suggesting that the diagnosis was gastric TB. The patient was then treated with antitubercular therapy regimen for 9 months. The previously documented mass in the stomach cardia was no longer visible on the follow-up endoscopy examination, and the patient was considered cured.

CONCLUSION

This case shows that gastric tuberculosis should be considered in patients with gastrointestinal symptoms, especially those living in TB endemic regions. Endoscopic examinations, such as EGD and EUS, may aid in the diagnosis of gastric tuberculosis.
