我院于1980-1986年,胸腔穿刺578例,其中238例有组织学对照。细胞学诊断假阳性7例,假阴性3例及20例分型错误。本文指出引起假阳性诊断的主要原因是:1.涂片中细胞量少;2.细胞退变;3.反应性组织细胞易与恶性细胞相混淆;4.不典型增生的柱状细胞难与类癌和高分化腺癌鉴别。引起假阴性诊断的原因是:1.未将组织学标准与细胞学诊断结合,2.漏诊。并对引起分型错误的原因加以讨论。
In our hospital from 1980 to 1986, thoracic cavity puncture 578 cases, of which 238 cases had histological control. Cytological diagnosis of false positives in 7 cases, false negatives in 3 cases and 20 cases of mistypes. This article points out that the main causes of false-positive diagnosis are: 1. Small amount of cells in the smear; 2. Degeneration of cells; 3. Reactive tissue cells are easily confused with malignant cells; 4. Difficulties of dysplasia of columnar cells Cancer and well-differentiated adenocarcinoma are identified. The causes of false negative diagnosis were: 1. Histological criteria were not combined with cytological diagnosis. 2. Missed diagnosis. And discuss the causes of mistyped errors.
