Synovialosarcomas are rare, malignant mesenchymal tumors common in adolescents and young adults. They preferentially affect the lower limbs. Much more rarely, at the level of the chest wall. Contrary to its name, synovialosarcoma does not develop from synovial tissue. We report the case of a 17-year-old adolescent girl, followed for monophasic synovialosarcoma of the chest wall, the diagnosis of which was confirmed by immunohistochemistry. Treatment consisted of neoadjuvant poly chemotherapy followed by concomitant radio chemotherapy and closing surgery. This observation confirms the value of multimodal management in the treatment of this type of pathology.
