目的探讨分泌粘液的食管癌组织起源及细胞学诊断中的问题。方法对20例分泌粘液的食管癌病理切片和细胞学涂片进行形态学对照观察。结果分泌粘液的食管癌细胞学涂片中常出现粘液背景或粘液细胞；细胞学与病理切片的符合率达90％。结论细胞学有助于对分泌粘液食管癌的诊断；分泌粘液的食管癌可能起源于食管固有腺。
Objective To investigate the origin and cytological diagnosis of esophageal cancer tissue secreting mucus. Methods Pathological sections and cytological smears of 20 esophageal carcinomas secreting mucus were observed by morphology. Results Mucinous background or mucous cells often appeared in esophageal cancer cell smears that secrete mucus; the coincidence rate between cytological and pathological sections was 90%. Conclusion Cytology is helpful in the diagnosis of secretory mucinous esophageal cancer; esophageal carcinoma secreting mucus may originate from the inherent esophageal gland.
