血清生化学标记、超微形态及免疫组织化学等检查的常规化,使每个肿瘤病例瘤细胞特征的判定较以前更简便准确,这些检查逐渐阐明了肿瘤的分化方向和表现特征的多样性,也阐明了肿瘤细胞用通常的染色难以确定的主要表现特征。本文所述的肝样肿瘤即是借助这些检查确定的。肝样肿瘤是发生脏器、临床病理学性质各异的肿瘤的总称。其共性都包含异位性肝细胞性肿瘤这一概念。肝样肿瘤判定的有关问题假如把异位性肝细胞肿瘤看作是发生于肝外脏器,包括以肝细胞为表现形的肿瘤,那
The routineization of serum biochemical markers, ultramicromorphology, and immunohistochemistry has made the determination of the tumor cell characteristics of each tumor case easier and more accurate than ever. These tests have gradually elucidated the diversity of tumor differentiation directions and performance characteristics. It also sheds light on the main performance characteristics of tumor cells that are difficult to determine with normal staining. The liver-like tumors described herein were determined by these tests. Hepatic tumors are the general name for tumors with various organs and clinical pathologies. The commonality includes the concept of ectopic hepatocellular carcinoma. Problems related to the determination of liver-like tumors If ectopic liver cell tumors are considered to occur in extrahepatic organs, including tumors in the shape of liver cells,
