本病又称韧带状瘤(desmoid tumor)或侵袭性纤维瘤病(aggressive fibromatosis),是介于良恶性之间的纤维性肿瘤。其特点为纤维组织的增生并形成瘤样病变,增生的纤维组织较为成熟,与纤维瘤相似,但无包膜。病变源自肌筋膜,常呈浸润性生长,侵袭性强,广泛发生干骨骼肌及筋膜,并向周围增殖扩散。完全切除后多反复复发,甚至有被迫而截肢 This disease, also known as desmoid tumor or aggressive fibromatosis, is a fibrous tumor that is between benign and malignant. It is characterized by the proliferation of fibrous tissue and the formation of tumor-like lesions, the proliferation of fibrous tissue is more mature, similar to fibroids, but no capsule. The lesions originate from the myofascial membrane and often show invasive growth. They have strong invasiveness. Dry skeletal muscles and fascia widely occur and spread to the surrounding areas. Repeatedly relapsed after repeated relapses, even with forced amputation
