title: [Rare primary chest wall sarcoma: the synovialosarcoma].
abstract: BACKGROUND
  Malignant primary tumours occurring in the thorax encompass a large group of tumours which may arise from the lung, mediastinal structures, the pleura or the chest wall.
  
  
  METHODS
  We report the case of a 37 year old patient, who presented with left sided chest pain. On clinical examination a right sided chest wall mass was identified. Chest X Ray showed a left sided upper mediastinal opacity, associated with a left sided pleural opacity. Thoracic CT scan revealed a large mass arising from the chest wall and infiltrating the mediastinum associated with a second chest wall mass at the level of the 8(th) and 9(th) right ribs. The biopsy of the chest wall mass revealed it to be a parietal synovialosarcoma. The patient responded to chemotherapy based on ifosfamid and doxorubicin as well as mediastino-pulmonary radiotherapy. There was an improvement in the patient's clinical and radiological state but the patient died by pulmonary embolism after the 3(rd) cause of treatment.
  
  
  CONCLUSIONS
  Chest wall synovialosarcoma has a poor prognosis, however, its chemosensitivity means that treatment may initially be effective.
