这是一类病变都发生在骨骼上的良性肿瘤性病变,但由于其组织学构成不同,各自的生物学行为也不尽相同。类肿瘤疾患一般定义为由骨囊肿、动脉瘤样骨囊肿、纤维异样增殖症及骨嗜酸性肉芽肿等组成的一类疾病,由于其生物学行为类似良性骨肿瘤,故在临床上常将其与良性骨肿瘤一同讨论。侵袭性良性骨肿瘤是在诊断上最容易与恶性肿瘤相混淆的病变,由于其具有局部侵袭性,对周围骨的破坏在影像 This is a benign neoplasm of a class of lesions that occurs on the bones, but their biological behavior is also different due to their different histological structures. Tumor-like diseases are generally defined as a group of diseases consisting of bone cysts, aneurysmal bone cysts, fibrous dysplasia and eosinophilic granuloma. Because of their biological behavior similar to benign bone tumors, they are often clinically used Discuss with benign bone tumor.
