Abstract

Osteosarcoma is the most common primary malignant bone tumor, with a higher prevalence among children and young adults. Its most frequent localization is the distal femur, followed by the proximal humerus and the proximal femur.We will describe the case of a 25-year- old male patient who presented in our clinic, accusing spontaneous pain and swelling, both originating from the left knee. The X-ray of the distal femur showed a heterogeneous mass around the left femoral metaphysis with massive periosteal reaction. The computerized tomography (CT) revealed cortical destruction, with extra-compartmental localization. The patient has later undergone to an incisional biopsy. The histopathology report showed the presence of a chondroblastic osteosarcoma. According to the multidisciplinary diagnosis, the tumor was finally classified as type IIB on the Enneking classification. In such cases, the elective surgical procedure is reconstructive surgery, consisting of wide resection of the distal femur, followed by modular reconstruction. After the surgery, the patient’s condition improved significantly and the functional outcome of the reconstructed joint was also satisfying.
