BackgroundMyxofibrosarcoma (MFS) is a rare malignant fibroblastic tumor that primarily occurred in proximal extremities of older people. However, MFS, especially radiation-Induced MFS is extremely rare in the head and neck. Local recurrence is very common, the diagnosis and treatment of MFS is always a great challenge. We presented one case of radiation-induced MFS, combined with previous literature, the clinical features, essentials of diagnosis and treatment modalities of MFS in head and neck were reviewed to better understand this rare entity.Case presentationHere, we reported a case of radiation-Induced MFS under left occipital scalp in a 20-year-old girl with a history of medulloblastoma surgery and radiotherapy in 2006. A total tumor resection was performed with preservation of the overlying scalp the underlying bone, and no adjuvant therapy was administered after surgery. Post-operative pathological diagnosis was high-grade MFS. Unfortunately, the tumor relapsed six month later. Then a planned extensive resection was carried out, followed by radiotherapy. In addition, intra-operative frozen section was sent to confirm negative surgical margin. No relapse occurred in 12-month postoperative follow-up.ConclusionsPlanned gross total resection (GTR) with negative margins is the reasonable choice and footstone of other treatments for MFS. Ill-defined infiltrated borders and the complicated structures make it a great trouble to achieve total resection of MFS in the head and neck. Therefore, adjuvant radiotherapy and chemotherapy seem more necessary for these lesions. Further studies are needed to confirm the efficacy of radio-chemotherapy for head and neck MFS. |
