[Clinical analysis of low grade myofibroblastic sarcoma in head and neck].

Objective: To explore the clinical characteristic, the CT, MRI features, diagnosis and treatment of low grade myofibroblastic sarcoma in head and neck.

Method: Six cases of low grade myofibroblastic sarcoma in head and neck were diagnosis and reviewed retrospectively. Routine preoperative CT and MRI examination were performed.

Result: All cases were operated one case with radiotherapy before operation was given with a total dose of 60 Gy. The patients were follow-up for 6 months to 5 year and no recurrence was found. No complications occurred in 6 cases.

Conclusion: It has been confirmed in this research that LGMS is a low-grade malignangt tumor. It was difficult to make early diagnosis through frozen section. The final diagnosis depend on paraffin section and immunohistochemisty. Extended local excision with tumor-free margin is the treatment of choice.
