Osteosarcoma metastasising to the duodenum and pancreas.
The incidence of metastatic osteosarcoma is increasing because of improved results following multi-agent chemotherapy and resection of the primary tumour. Metastases occur most commonly in the lungs, whereas bowel metastases are rare. We describe a 25-year-old female who presented with melaena six years after successful resection of an osteosarcoma of her right femur, and one year after resection of a solitary pulmonary metastasis. Imaging revealed a lesion arising within both the duodenum and the pancreas for which a Whipple's pancreatoduodenectomy was carried out, achieving complete resection. Histological examination confirmed the diagnosis of metastatic osteosarcoma. We believe this is only the second such case reported. At 11 months post-operatively she had no detectable disease. Although rare, osteosarcoma can metastasise to the intestine. The surgeon must be aware of this complication, and that bowel metastases are potentially resectable.
