错构瘤是在胚胎发育期间或稍后的身体发育过程中发生的异常性组织增殖。来源于组织器官局部的组织岛,可能脱落 而无功能。这种先天性的异常增殖属于组织结构性缺陷。错构瘤可以孤立生长,其组织结构无功能意义和目的。这是由于 错构瘤本身来源于胚胎组织,所以不会影响人体任何规律性或功能性的活动。这种类似于肿瘤生长过程的错构瘤与增殖性 Hamartomas are abnormal tissue proliferation that occurs during the development of the embryo or later in the body. Tissue islands, which originate from local tissue and organs, may fall off without function. This congenital anomalous proliferation is a structural defect. Hemangioma can grow in isolation, its organizational structure without functional significance and purpose. This is because the hamartoma itself is derived from the embryonic tissue and therefore does not affect any regular or functional activity of the body. This is similar to the tumor growth process hamartoma and proliferative
