%X Introducci車n: Los sarcomas son tumores malignos poco frecuentes, siendo raros en cabeza y cuello. En su etiolog赤a se involucran factores como agentes qu赤micos, radiaci車n, inmunosupresi車n y s赤ndromes y anomal赤as gen谷ticas. Caso cl赤nico: Var車n de 64 a os, que presenta lesi車n en piel de mejilla derecha de un a o de evoluci車n, localizaci車n en la que present車 hace veinte a os un carcinoma basocelular tratado con radioterapia. Tras descartar existencia de met芍stasis, se realiz車 ex谷resis de la lesi車n con m芍rgenes de seguridad y reconstrucci車n con colgajo de Mustard谷. Se complement車 el tratamiento con radioterapia. Discusi車n: El diagn車stico es anatomopatol車gico, siendo fundamental descartar afectaci車n metast芍sica. Para mejorar la supervivencia y disminuir su elevada tasa de recidiva, deber赤an tratarse de forma multidisciplinar (cirug赤a, radioterapia y/o quimioterapia). Conclusi車n: A pesar de su baja frecuencia, los sarcomas deben estar presentes en el diagn車stico diferencial de toda lesi車n que aparezca en zonas radiadas previamente, especialmente en la piel facial. 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 Mustard谷 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.
