Ewing’s sarcoma is a bone tumor, considered one of the most aggressive, for its great capacity of metastasizing. Higher incidence in men, appears almost exclusively in the first three decades of life. Affects the long bones in the metaphyseal region, at its proximal end; the most affected are the femur, iliac, tibia, humerus, fibula and ribs; however, there are atypical locations such as in the hands, feet and extraosseous. The clinical case of a 13‐year‐old male adolescent patient, who two months before his medical attention presented a mass at the level of the second and third right costal arches that increased vertiginously. After routine and laboratory examinations performed at a third level complexity hospital, he was diagnosed with Ewing's Sarcoma, where 3 chemotherapy sessions were performed; however, despite the treatment, he presented brain and bone metastases. Ewing's tumor was highly aggressive and has a bleak prognosis.

Keywords: sarcoma, ewing, tomography, morbid metastasis.

RESUMEN

El Sarcoma de Ewing es un tumor óseo, considerado uno de los más agresivos, por su gran capacidad de metástasis. Tiene mayor incidencia en hombres, se presentan de forma casi exclusiva en las tres primeras décadas de vida, afecta a los huesos largos en la región metafisodiafisaria, en su extremo proximal, los más afectados son el fémur, el iliaco, la tibia, el humero, el peroné y las costillas. Sin embargo, existen localizaciones atípicas como en los pies manos y extraóseas. Se presentación el caso de un paciente adolescente masculino de 13 años, que dos meses antes de la atención médica presenta una masa a nivel de segundo y tercer arco costal derecho que aumenta de tamaño de forma vertiginosa. Posterior a exámenes de gabinete y laboratorio realizados en Hospital de Tercer Nivel de Complejidad, es diagnosticado de Sarcoma de Ewing en donde se realizan 3 sesiones de quimioterapia, sin embargo, pese el tratamiento presenta metástasis cerebrales y óseas, El tumor de Ewing es altamente agresivo y tiene un pronóstico sombrío

Palabras claves: sarcoma de ewing, tomografía, metástasis mórbida.
