肺部良恶性肿瘤发病率较高,典型病例的诊断并不困难,但在肿块形态、大小、密度、边缘与周围关系以及临床表现不典型时,对诊断有时确有困难。本文回顾经手术病理证实,而术前误诊为中心型肺癌的教训,仅供同道们参考。 The incidence of benign and malignant lungs is high, and the diagnosis of typical cases is not difficult. However, it is sometimes difficult to diagnose when the shape, size, density, marginal and peripheral relationships, and clinical manifestations of the tumor are not typical. This article reviews the surgical pathology confirmed, and misdiagnosed as the center of lung cancer before the lessons, only for their reference.
