本研究旨在对应用细胞学诊断结核性溃疡的可靠性作出评估．资料包括６７例口腔慢性溃疡，临床诊为结核或其它疾病，经细胞学检查作出诊断．根据病理检查或临床治验确立的最后诊断，有１８例为非结核性溃疡，其中鳞癌１３例．结果显示，临床上确诊结核十分困难，鉴别重点是鳞癌．对照最后诊断，细胞学对结核性溃疡的诊断敏感度和特异性分别达８４％和８９％，表明该检查有一定的实用价值．文中对误诊病例作了分析，并就恰当地应用细胞学技术提出了建议．
The aim of this study was to evaluate the reliability of cytological diagnosis of tuberculous ulcer. Data include 67 cases of chronic oral ulcers, clinically diagnosed as tuberculosis or other diseases, diagnosed by cytology. According to the pathological examination or clinical examination established the final diagnosis, 18 cases of non-tuberculous ulcers, including squamous cell carcinoma in 13 cases. The results show that clinically confirmed tuberculosis is very difficult to identify the focus of squamous cell carcinoma. According to the final diagnosis, the sensitivity and specificity of cytology in the diagnosis of tuberculous ulcer were 84% and 89% respectively, indicating that the test has some practical value. The article analyzes misdiagnosed cases and makes recommendations on the proper application of cytological techniques.
