Condrosarcoma de estern贸n en paciente masculino de 58 a帽os: reporte de caso: Surgical repair of sternum chondrosarcoma in a 58-year-old male patient: Case Report
Sternum chondrosarcoma is an infrequent malignant neoplasm which occurs mainly in adults over 50 years old. Grade 1 chondrosarcoma is the most frequent among the heterogenous group of tumors that fall into this classification, however, it is most frequently presented in the pelvic region, in long bones of the appendicular skeleton and in the costal region. The fact that it presents in the sternal region compromises the constitution of nearby organs. Due to radiotherapy and chemotherapy having a scarce therapeutic effect, we proceeded with surgical intervention where a wide resection of the sternal chondrosarcoma and liver metastasectomy was performed, subsequently, the chest wall was rebuilt using titanium plates and microsurgical right dorsal muscle flap. The final result was favorable. We present a conventional chondrosarcoma (grade 1) case at the xyphoid process level with liver metastasis.El condrosarcoma de estern贸n es una neoplasia maligna poco frecuente que se presenta mayormente en adultos mayores de 50 a帽os. El condrosarcoma grado 1 es el m谩s frecuente dentro del grupo heterog茅neo de tumores que entran en esta clasificaci贸n, sin embargo, tiene una presentaci贸n m谩s frecuente en la regi贸n p茅lvica, en huesos largos del esqueleto apendicular y en la regi贸n costal. El hecho de presentarse en la regi贸n esternal puede comprometer la constituci贸n de 贸rganos cercanos. Debido a que la radioterapia y la quimioterapia tienen un escaso efecto terap茅utico se procedi贸 con la intervenci贸n quir煤rgica donde se realiz贸 la resecci贸n amplia del condrosarcoma esternal y la metastasectom铆a hep谩tica, posteriormente se reconstruy贸 la pared tor谩cica mediante placas de titanio y un colgajo microquir煤rgico de m煤sculo dorsal ancho derecho. El resultado final fue favorable. Se presenta el caso de un condrosarcoma convencional (grado 1) a nivel del ap茅ndice xifoides conmetast谩sis a h铆gad
