通常在X线片上见不到石棉肺的结节,在组织切片上亦很少发现。但在实验性石棉肺的病理改变早期,却出现有类似小结节的形态,这些小结节不完全纤维化,只在边缘有轻微的硬化。本文目的在于研究石棉结节中细胞成分的组织学特征,以及它们和矽结节的区别。 Nodules of asbestosis are usually not seen on the X-ray film and rarely seen on the tissue section. However, in the early stages of pathological changes in experimental asbestosis lungs, a similar nodular morphology appeared. These nodules were not completely fibrillating and showed slight hardening at the edges. The purpose of this paper is to study the histological features of cellular components in asbestos nodules and their differences from silicone nodules.
