Periosteal chondrosarcoma, also known as juxta-cortical chondrosarcoma, is a rare malignant cartilaginous tumor arising from the external surface of the bone [1, 2]. Imaging features are often specific. Recognizing periosteal chondrosarcoma and differentiating it from other surface tumors is of capital importance because the prognosis is excellent after adequate local surgery alone. Metastasis is late and very rare [3]. We report the case of a young 23 year old, who consulted for left thigh pain evolving for 3 months without inflammatory signs or deterioration of the general condition. A conventional radiographs, computed tomodensitometry and magnetic resonance imaging were performed and were in favor of periosteal chondrosarcoma. The patient underwent a biopsy which confirmed the diagnostic.
