EUS in the diagnosis of pathologically undiagnosed esophageal tuberculosis.

Background: Esophageal tuberculosis (ET) is relatively rare, and the diagnosis is challenging. The aim of this study was to evaluate the clinical features of ET and highlight the role of endoscopic ultrasonography (EUS) in the diagnosis of pathologically undiagnosed ET.

Methods: We retrospectively analysed the clinical features, radiological performances, conventional endoscopic appearances, EUS features, treatment and outcomes of pathologically undiagnosed ET between January 2011 and December 2018.

Gastric tuberculosis mimicking submucosal tumor: a case series.

Background: Gastric tuberculosis mimicking submucosal tumors is extremely rare and often misdiagnosed.

Case Presentation: Three cases of gastric tuberculosis mimicking submucosal tumors were identified among patients admitted to local county hospitals because of upper abdominal discomfort and pain, with gastroscopy showing gastric submucosal tumors. The patients were admitted to our hospital for endoscopic ultrasonography (EUS).
