Syndrome cave supérieur et tamponnade révélant une tumeur desmoïde du médiastin

Desmoid tumors are rare forms of low grade malignancies. They are characterized by a strong potential of local invasion. Although they are considered histologically benign they behave aggressive locally. They typically occur in the abdominal wall or within the abdomen. Mediastinal localisation is very rare. The only curative treatment is wide surgical excision but the surgery is difficult and the risk of local recurrence is high.
