Chondrosarcoma is a tumor of cartilaginous origin that usually occurs in adults, and tends to grow slowly and to metastasize late, via the veins to the lungs. When the tumor occurs in a child, its occurs often is different, and it runs a rapidly fatal course with early metastases to the lungs much like osteosarcoma. The presently reported case is one of chondrosarcoma of the femur from which metastases occurred to the mesentery and wall of the small bowel, a circumstance previously unreported. When the patient was last seen, twelve years after disarticulation of the hip and five years after partial resection of metastases, she apparently was well.
