[A rare case of bone metastasis from gastro-intestinal stromal tumour: place of radiotherapy]. / À partir d'un cas rare de métastases osseuses d'une tumeur stromale gastro-intestinale : intérêt de la radiothérapie.

Gastro-intestinal stromal tumours are the most common mesenchymal neoplasms of the gastrointestinal tract. Their usual metastatic sites are the liver and the peritoneum, but gastro-intestinal stromal tumours rarely metastasize to the bones. We report the case of a 56-year-old male presenting with bone lesions six years after initial surgical resection. We discuss through this paper the possibilities of management of these lesions and the place of radiotherapy.
