肺泡细胞癌(以下简称肺泡癌)是原发性肺癌中较少见的一型,有人统计1682例肺癌,本型只占2.8%,此种癌细胞的形态在脱落细胞学检查时,往往很难与支气管腺癌细胞区别,以致常将它泛诊为腺癌细胞,有时甚至误诊为低分化鳞癌细胞。实际上这种癌细胞与腺癌细胞以及低分比鳞癌细胞在形态上是有所不同的。Sabbatsberg医院细胞实验室曾提出过腺癌和肺泡癌两种癌细胞的鉴别特征,但还不够详细。一年多来我们在痰液标本中发 Alveolar cell carcinoma (hereinafter referred to as alveolar carcinoma) is a rare type of primary lung cancer. Some people counted 1,682 lung cancers. This type only accounts for 2.8%. The shape of this type of cancer cells is often very good at exfoliative cytology. Difficult to distinguish with bronchial adenocarcinoma cells, so often it is widely diagnosed as adenocarcinoma cells, and sometimes even misdiagnosed as poorly differentiated squamous cancer cells. In fact, the cancer cells are different in morphology from adenocarcinoma cells and low-specificity squamous cancer cells. Sabbatsberg hospital cell laboratory has proposed the distinguishing characteristics of adenocarcinoma and alveolar carcinoma, but not enough detail. For more than a year we have sent samples in sputum
