Objetivo: conocer un paciente con sarcoma pleomórfico indiferenciado en la región del muslo derecho.  Presentación del caso:  paciente de 52 años de edad, de raza blanca, masculino, sin antecedentes mórbidos de salud, acude a la consulta externa de Ortopedia y Traumatología por referir tener una bolita en el muslo derecho que en el último mes ha crecido y se acompaña de ligero dolor en la zona. Mediante la exploración física se observó aumento de volumen a nivel del muslo derecho en la cara posterolateral. A la palpación se comprobó la tumoración de bordes irregulares, mal definidos, móvil de localización por debajo de la fascia y consistencia dura. Al tener en cuenta todos los elementos anteriores, se decidió llevar el paciente al quirófano, para tratamiento de tipo quirúrgico, donde se realizó exéresis de la tumoración descrita con anterioridad, la que fue enviada al Departamento de Anatomía Patológica para estudio histológico que reveló sarcoma pleomórfico indiferenciado con células gigantes.  Conclusiones: el sarcoma pleomórfico indiferenciado es una tumoración maligna infrecuente de partes blandas con un pronóstico reservado. Los síntomas y signos son más evidentes en el periodo de crecimiento rápido. Los exámenes imagenológicos como el ultrasonido de alta definición y la imagen de resonancia magnética son los más importantes. El tratamiento de elección primario es el quirúrgico, seguido de la radio y quimioterapia.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT  Background:  soft tissue sarcomas are aggressive tumors that can cause the death of patients, there are many histological types and can be located anywhere in the human body.  Objective:  to report a patient with undifferentiated pleomorphic sarcoma in the right thigh region.  Case report:  a 52-year-old white male patient with no morbid health history, who goes to the external Orthopedics and Traumatology clinic referring to have a little ball in the right thigh that has grown in the last month and it is accompanied by slight pain in the area. On physical examination, an increase in volume was observed at the level of the right thigh in the posterolateral area. On palpation, the tumor of irregular, bad-defined edges, mobile location below the fascia and hard consistency was checked. Taking into account all the previous elements, it is decided to take the patient to the operating room, for surgical treatment, where the tumor described above was extracted, it was sent to the Pathology department for histological study that revealed undifferentiated pleomorphic sarcoma with giant cells.  Conclusions:  undifferentiated pleomorphic sarcoma is an uncommon soft tissue tumor with a poor prognosis. Symptoms and signs are more evident in the period of rapid growth. Imaging tests such as high definition ultrasound and magnetic resonance imaging are the very importants. The primary treatment of choice is surgery, followed by radio and chemotherapy.]]></p></abstract>
