在肝脏良性肿瘤中,肝错构瘤是罕见疾病。依据其组成的组织成分多少,分为起源于内胚层和起源于中胚层两类,前者又分为实质性错构瘤(parenchrmal hamartoma),以肝细胞增生为主体。胆管错构瘤,以胆管和纤维胶原基质增生为主体。后者又分为间叶性错构瘤(mesenchymal hamartoma),以间叶组织增生为主体。血管性错构瘤以血管和纤维结缔组织增生为主体,临床所见以间叶性错构瘤为多。肿瘤内有囊肿存在为其特征,囊内有无色或黄色浆液。查阅英文文献约有100例,日本报道3O例,我国亦有个案报告,未能计数。发病年龄大多数在2岁以内,最小15天,女性略多于男性,
Hepatic hamartoma is a rare disease in benign liver tumors. According to the composition of its composition, it is divided into two types: endoderm and mesoderm. The former is also divided into parenchymal hamartoma and hepatocyte hyperplasia. The bile duct hamartoma is mainly composed of proliferation of bile ducts and fibrous collagen matrix. The latter is further divided into mesenchymal hamartoma (mesenchymal hamartoma), with mesenchymal malformation as the main body. Vascular hamartomas are mainly composed of vascular and fibrous connective tissue hyperplasia, and there are many mesenchymal hamartomas seen in clinic. The presence of cysts in tumors is characterized by a colorless or yellow serum within the capsule. There are about 100 cases of reading English documents, 3O cases of reports from Japan, and cases in China. The age of onset is mostly within 2 years of age and the minimum is 15 days. Women are slightly more than men.
