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). As EUS revealed evidence of tuberculosis for the first two patients, we first considered gastric tuberculosis. However, because of atypical characteristics of the miniature ultrasonic probe and EUS, the lesion in the third patient was misdiagnosed as a stromal tumor, and the patient underwent endoscopic submucosal dissection (ESD), and intraoperative characteristics and postoperative pathology confirmed the lesion to be tuberculosis. CONCLUSIONS EUS is of great value in the diagnosis of gastric tuberculosis, especially gastric tuberculosis mimicking submucosal tumors. Here, we summarize some significant characteristics of gastric tuberculosis by EUS, which will be of substantial value to clinical work.

模仿粘膜下肿瘤的胃结核：一个病例系列。

背景技术模仿粘膜下肿瘤的胃结核极为罕见，常常被误诊。病例介绍在上县医院因上腹部不适和疼痛而入院的患者中，发现了三例模仿粘膜下肿瘤的胃结核病例，胃镜检查显示出胃粘膜下肿瘤。患者入院接受内镜超声检查。由于EUS揭示了前两名患者的结核病证据，因此我们首先考虑了胃结核。但是，由于微型超声探头和EUS的非典型特征，第三例患者的病变被误诊为基质肿瘤，患者接受了内镜下粘膜下剥离术（ESD），术中特点和术后病理证实该病灶为结核病。结论EUS在胃结核的诊断中具有重要的价值，特别是模仿黏膜下肿瘤的胃结核。在这里，我们总结了EUS引起的胃结核的一些重要特征，这些特征对临床工作具有重要价值。
