RUBIO-CORREA, Isidoro et al. Radiation-induced mixed cutaneous sarcoma. Rev Esp Cirug Oral y Maxilofac [online]. 2012, vol.34, n.2, pp.81-84. ISSN 2173-9161.

Introduction: Sarcomas are malignant tumors that are infrequent, being rare in the head and neck. Factors such as chemical agents, radiation, immunosuppression, and genetic syndromes and abnormalities are involved in their etiology. Case report: A 64-year-old man developed a skin lesion on the right cheek one year earlier at the site where he had presented a basal cell carcinoma 20 years earlier that was treated with radiation therapy. After ruling out the existence of metastasis, the lesion was treated by surgical resection with safety margins and reconstruction with the Mustardé flap. Treatment was supplemented with radiation therapy. Discussion: The diagnosis of sarcomas is histopathologic and it is essential to rule out metastasis. To improve survival and reduce the high rate of recurrence, a multidisciplinary approach to treatment should be used (surgery, radiation therapy and chemotherapy). Conclusion: Despite the low frequency of sarcomas, these tumors must be considered in the differential diagnosis of any lesion that appears on previously irradiated areas, especially on facial skin.
