RESUMO
Synovial sarcoma is a relatively common soft tissue sarcoma particularly in the adolescent and young adult. We report an unusual case of a synovial sarcoma arising within a popliteal cyst in a 13-year-old female presenting with bilateral popliteal cysts. MR imaging demonstrated the cyst with evidence of subacute haemorrhage and a discrete nodule of tumour.

Method. We performed a two-stage vascularized ipsilateral fibular graft transfer for segmental tibial defect following excision of malignant bone tumours.Results. We report 10 patients who had this procedure with an average follow-up of 116 months.The graft was transposed medialy on its vascular pedicle by two-stage surgery. Full weight bearing was achieved in six patients at 8-43 months postoperatively, but every patient had a significant complication.Discussion. The use of this method in isolation is not recommended for reconstruction of the tibia following tumour excision.
RESUMO
We carried out extensible endoprosthetic replacement of the proximal or total humerus in 18 children aged between six and 12 years, after resection of primary bone tumours mainly for osteosarcoma and Ewing's sarcoma. In 11 patients we performed 44 lengthening procedures, with an average of two per child annually and a mean total extension of 29.9 mm per patient. We were able to achieve lengthening of the operated limb with few complications and a mean functional rating of 79.3% according to the Enneking system. Progressive lengthening of these prostheses does not adversely affect the overall function of the arm, and superior subluxation of the head of the prosthesis has not been a problem.

Purpose. Clear cell chondrosarcoma is a rare variant of chondrosarcoma. Six cases are herein reported.Subjects. We have treated six patients with clear cell chondrosarcoma in the past 28 years, representing 1.6% of all chondrosarcomas seen in this time period.Results and Discussion. Half the patients had been initially underdiagnosed and inappropriately treated.Conclusions. Our results and our review of the literature highlight the fact that inadequate initial treatment leads to a high rate of both local recurrence and metastasis whilst wide initial excision is usually curative.
