前言本分类主要依据肿瘤的光学显微镜特征而提出,因此,涉及到形态上可认识到的细胞类型和常规光镜所见到的组织学图像。肿瘤一词与新生物同义语,“肿瘤样”短语只适用于在临床上或形态上类似新生物的损伤,但决不意味着在生物学上是以新生物方式生长。他们都被包括在本著作中,这是因为他们在鉴别诊断上会产生很多问 Foreword This classification is based on the optical microscope characteristics of tumors. Therefore, it involves morphologically recognizable cell types and histological images seen with conventional light microscopy. The term tumor is synonymous with neoplasms. The “tumor-like” phrase is only applicable to lesions that resemble new organisms clinically or morphologically, but in no way means that it is biologically grown in a new biological way. They are all included in this book because they have a lot of questions about differential diagnosis.
