鉴别肿瘤的良恶性质,一直是肿瘤诊断和治疗的重要步骤。交界性肿瘤,其种类繁多,几乎在临床手术科室均可遇到。实践表明,肿瘤的形态结构和生物学行为千差万别,而且肿瘤的形态结构并非绝对都能反应出其生物学行为。因此,可以说肿瘤的形态学也有一定的局限性。对少数肿瘤来说,即使应用最新的形态学方法,也难以确定其良恶性质。有待于临床进行严密地观察,才能得出正确的结论。其原因在于:一方面是因某种肿瘤在形态结构上既 Identifying the benign nature of tumors has always been an important step in the diagnosis and treatment of tumors. Borderline tumors have a wide variety of types and can be encountered in almost all clinical operating departments. Practice shows that the morphological structure and biological behavior of tumors vary widely, and the morphological structure of tumors can not absolutely reflect its biological behavior. Therefore, it can be said that the morphology of the tumor also has certain limitations. For a small number of tumors, even if the latest morphological methods are applied, it is difficult to determine their benign nature. To be closely observed in the clinic, can we come to a correct conclusion. The reason for this is that on the one hand it is due to the morphological structure of certain tumors
