<abstract xmlns="http://www.w3.org/1999/xhtml">Introduction. Chondrosarcoma is a malignant tumor of cartilaginous origin representing approximately 20-30% of all bone malignant tumors and occupying the second place in terms of their incidence. It usually affects adults between 40 and 60 years old, but can be encountered at older ages as well.Materials and methods. We report the case of a 55-year-old male patient who presented to our department with 2 weeks-long right hip pain and partial loss of functionality in right limb. We performed X-rays, magnetic resonance imaging, computed tomography, bone scintigraphy, and angiography, which established the diagnosis of pelvic tumor. Biopsy of the tumor was performed by iliofemoral approach and its result showed moderately differentiated chondrosarcoma. Orthopaedic surgery was performed, with tumoral removal within oncological limits, pelvic reconstruction using acrylic bone cement impregnated with Vancomycin and total hip arthroplasty.Results were assessed using the Musculoskeletal Tumor Rating Scale and a score of 23 out of 35 was obtained (the higher the better). Postoperative complications consisted in flap-skin necrosis that resolved within 2 months after surgery.Conclusion. Bone defects repair using antibiotic impregnated cement drastically reduced the rate of postoperative infections, thus decreasing both morbidity and mortality. In spite of technological advancement, long-term prognosis remains reserved in chondrosarcoma, due to its specific aggressivity, resistance to chemo- and radiotherapy and high rate of recurrence.</abstract>
