Introduction: Although radiation-induced sarcomas are widely documented, most reports focus on pleomorphic malignant fibrous histiocytomas (high-grade undifferentiated pleomorphic sarcomas); few case studies involve myxofibrosarcomas. This paper reports on a grade II myxofibrosarcoma of the neck arising secondary to earlier chemotherapy and radiotherapy. Material and methods: A 61-year-old male received chemotherapy plus radiotherapy in 1983 for nodular sclerosing Hodgkin's lymphoma. Twenty-six years after completing treatment, the patient developed a grade II myxofibrosarcoma involving radiated soft tissue on the left side of the neck. Results: The tumor was removed. The tumor mass weighed 90 g and measured 6 × 5 × 4.5 cm and the histological examination revealed a grade-II superficial malignant myxoid spindle-cell tumor displaying a multinodular growth pattern. Immunohistochemical staining was positive for CD34 and negative for smooth muscle actin and desmin. Conclusions: Given the increasing use of adjuvant therapies, particularly in the early stages of cancer, patients should be closely monitored to ensure detection of radiation/chemotherapy-induced sarcomas.
