Basaloid squamous carcinoma (BSC) of the esophagus is a rare esophageal tumor. A 79-year-old man with a history of proximal gastrectomy for gastric adenocarcinoma in 2000 was followed-up by esophagogastroduodenoscopy (EGD) annually. In June 2010, EGD revealed a new protruding lesion in the cervical esophagus. The small lesion was approximately 5 mm in size. A biopsy specimen showed poorly differentiated squamous cell carcinoma. We performed endoscopic mucosal resection using a cap-fitted endoscope (EMRC). The histological diagnosis of the endoscopically resected specimen was BSC and the invasion depth was limited to the muscularis mucosae. Horizontal and vertical margins were negative. We report the case of superficial BSC in the cervical esophagus successfully resected by EMRC.
食管基底样鳞状细胞癌（BSC）是一种罕见的食管肿瘤。一名79岁男性，2000年因胃腺癌接受近端胃切除术，此后每年接受食管胃十二指肠镜检查（EGD）随访。2010年6月，EGD检查发现颈段食管有一个新的隆起性病变。该小病变大小约5毫米。活检标本显示为低分化鳞状细胞癌。我们使用带帽内镜进行了内镜黏膜切除术（EMRC）。内镜切除标本的组织学诊断为BSC，浸润深度局限于黏膜肌层。切缘水平和垂直方向均为阴性。我们报告了一例通过EMRC成功切除的颈段食管浅表BSC病例。
