目的:提高临床对上颌窦恶性纤维组织细胞瘤(MFH)的认识。方法:报告分析经病理确诊的5例MFH的临床资料。结果:5例均手术,术后均行放疗,1例复发后化疗。5例随访至今,3例复发。无一例死亡。结论:对病史不长,有一侧上列牙痛,面部麻木,伴面颊部结节样隆起患者,应考虑到MFH。结合CT、术中所见、病理检查等确诊;MFH恶性程度一般较低,少有转移者,但易复发。适当扩大手术切除范围,结合术后放疗,可减少复发。
Objective: To improve the clinical knowledge of maxillary sinus malignant fibrous histiocytoma (MFH). Methods: The report analyzed 5 cases of pathologically confirmed MFH clinical data. Results: All the patients underwent surgery, radiotherapy was performed after operation, and chemotherapy was performed after recurrence. 5 cases were followed up till now, 3 cases relapsed. No one died. CONCLUSIONS: MFH should be considered for patients who have not had a long history of one of the following toothaches, facial numbness, and buccal-like bumps. Combined with CT, intraoperative findings, pathological examination confirmed; MFH malignancy is generally low, few metastases, but easy to relapse. Appropriate to expand the scope of surgical resection, combined with postoperative radiotherapy, can reduce recurrence.
