目的回顾28例小儿臀部硬纤维瘤的临床资料和手术治疗的经验。方法 28例均行手术治疗,7例肿瘤围绕坐骨神经者,切开肿瘤分离出神经后切除肿瘤,1例同侧肢体多部位病变,分别切除。结果术后获得随访24例,随访2~28 a,平均12 a 3个月,10例肿瘤复发,复发率40.4%。结论硬纤维瘤是具有侵袭性生长,切除后易局部复发,但是不发生转移和恶变的肿瘤。虽为良性,但是恶性生长,应早期诊断。广泛切除受累的臀部、韧带、骨膜以及周围2~3 cm范围的正常组织,可以减少复发。 Objective To review the clinical data and surgical treatment experience of 28 cases of pediatric hip dysplasia. Methods Twenty - eight cases underwent surgical treatment. Seven of the tumors were located around the sciatic nerve. The tumor was excised and the tumor was excised after excision of the tumor. One case of multiple sites of ipsilateral limb lesion was excised. Results 24 cases were followed up for 2 ~ 28 years, with an average of 12 months and 3 months. The recurrence rate was 40.4% in 10 patients. Conclusion Diffuse fibroids are invasive tumors with easy local recurrence after resection but without metastasis and malignancy. Although benign, but malignant growth, should be diagnosed early. Extensive resection of the affected buttocks, ligaments, periosteum, and surrounding normal tissue in the 2-3 cm range can reduce recurrence.
