Endoscopic ultrasound-guided sampling is indicated to achieve an accurate diagnosis of subepithelial lesions of the stomach when a standard biopsy fails. Gastric carcinoma with lymphoid stroma (GCLS) is located under the epithelial layer with dense lymphocytic infiltration, making a pathological diagnosis by a biopsy difficult. We herein report a case of the pathological diagnosis of GCLS using an endoscopic ultrasound-guided fine-needle biopsy. The patient underwent distal gastrectomy and was diagnosed with Epstein-Barr virus-negative cancer.
当标准活检未能成功时，内镜超声引导下采样可用于准确诊断胃黏膜下病变。淋巴样间质胃癌（GCLS）位于上皮层下方，伴有密集的淋巴细胞浸润，通过活检进行病理诊断较为困难。我们在此报告一例使用内镜超声引导下细针穿刺活检对GCLS进行病理诊断的病例。该患者接受了远端胃切除术，被诊断为 Epstein-Barr 病毒阴性癌。
