内镜下切除食管良性颗粒细胞瘤2例

Endoscopic resection of benign esophageal granular cell tumors:Report of two cases

食管颗粒细胞瘤在临床上较少见,大部分为孤立性结节且多无特异性临床症状,多在胃镜检查时被发现.对于食管颗粒细胞瘤仅依据组织学诊断不能确定肿瘤的良恶性.随着内镜技术的广泛应用,肿瘤的发现率及治疗方式在不断改变.本文报道经内镜下切除食管颗粒细胞瘤2例,并查阅相关文献进行复习.

Granular cell tumors of the esophagus are rare and mostly isolated lesions,many of which have no clinical symptoms and are usually accidentally discovered during annual endoscopic examination.Benign and malignant GCTs have similar histopathology,and there are no clear histological diagnostic criteria for the differentiation of benign and malignant tumors.With the wide application of endoscopic techniques,the detection rate of esophageal GCTs and treatment strategy have greatly changed.Here we report two cases of benign GCTs of the esophagus and reviewed the literature.
