目的：探讨食管中段腺癌的细胞学诊断意义。方法：对２０例食管腺癌病例的组织切片和细胞学涂片进行形态学对照观察。结果：印戒细胞癌３例，粘液腺癌７例，管状腺癌６例，腺鳞癌２例，粘液表皮样癌２例。其细胞学的共同特征为细胞学涂片中常出现粘液背景或含粘液的癌细胞；细胞学与病理组织学诊断的符合率达９０％。结论：细胞学有助于食管腺癌的诊断；食管腺癌可能起源于食管固有腺
Objective: To explore the significance of cytological diagnosis of esophageal adenocarcinoma. Methods: Morphological observations were performed on tissue sections and cytological smears of 20 cases of esophageal adenocarcinoma. RESULTS: There were 3 cases of signet ring cell carcinoma, 7 cases of mucinous adenocarcinoma, 6 cases of tubular adenocarcinoma, 2 cases of adenosquamous carcinoma and 2 cases of mucoepidermoid carcinoma. The common feature of cytology is that mucous backgrounds or mucin-containing cancer cells often appear in cytology smears; the coincidence rate of cytology and histopathology diagnosis is 90%. Conclusion: Cytology is helpful for the diagnosis of esophageal adenocarcinoma; esophageal adenocarcinoma may originate from the inherent esophageal gland
