1/9. Case report: Unusual peritoneal spreading by metastatic osteosarcoma of the tibia.

    We report a 17-year-old boy with chondroblastic osteosarcoma initially found in left proximal tibia. He received surgical resection and chemotherapy. However, a lung metastasis was found 4 years later. Despite intensive chemotherapy, the metastatic osteosarcoma of lung continued to invade the ribs and later into retroperitoneum and liver. The metastatic pattern of chondroblastic osteosarcoma of tibia directly to the chest and then into the abdomen is unusual.

2/9. Giant cell tumor of tendon sheath simulating giant cell tumor of bone: report of a case.

    A 24-year-old male patient presented with a painful eccentric lytic lesion of the proximal tibial epiphysis with a soft tissue component. Clinical and radiological assessment led to the tentative diagnosis of aggressive giant cell tumor of bone. The patient was treated with curettage, high-speed burr, and cementation after intraoperative pathology consultation. The final pathological report indicated that the tumor was giant cell tumor of the tendon sheath with bone invasion. Although uncommon, GCTTS should be considered in the differential diagnosis of such lesions when there is a prominent soft tissue component. Although the resection was intralesional, the thermal effect of the cementation of the involved cavity and complete removal of the tendon sheath may allow successful local control conjecture of lesions that otherwise present with clinical and radiographic findings suggesting giant cell tumor of the bone.

3/9. Multicentric contiguous variant of epithelioid angiosarcoma of the bone. A rare variant showing angiotropic spread.

    Epithelioid angiosarcoma of the bone is a rare tumor and is a diagnostic challenge. Here we present an autopsy case of a 62-year-old man with multifocal osteolytic lesions in the extremities and the pelvis. The initial diagnosis of a tibial biopsy was poorly differentiated adenocarcinoma. On the occasion of autopsy, a fungating thrombotic nodule was found at the anterior wall of the right atrium, and small hemorrhagic infarcts with tumor thrombi were found in the lung. Histologically, the above lesions were identical to the former tibial biopsy and they showed large eosinophilic epithelioid cells with irregular ovoid nuclei and prominent eosinophilic nucleoli. Rare intracytoplasmic lumina were identified. Immunohistochemically, the tumor cells were positive for cytokeratins (CAM5.2 and AE1/AE3), CD31, factor viii-related antigen, and vimentin. This case showed angiotropic spread of the tumor only to the right atrium and the lung, with no solid mass in other organs. Multicentric epithelioid angiosarcoma of the bone is a pitfall in pathological diagnoses, especially if a strong radiological impression of metastatic carcinoma is provided. Therefore, pathologists should be aware of this rare variant.

4/9. The Ilizarov method in the treatment of malignant neoplasms of the tibia.

    A total of 3 malignant neoplasms of the tibia are presented: 1 is a mesenchymal chondrosarcoma of the tibial pylon (male aged 14 years), and 2 are cases of squamous skin carcinoma of the leg with tibial infiltration (1 male and 1 female aged 32 and 64 years, respectively). The resections carried out (16.5 cm on the average) were treated by bone transport. Simple transport was used in the first patient, double in the other two. At the end of transport a second surgical stage involving astragalotibial arthrodesis was performed in the first case, and revision of the junction site of bone segments transported with application of autoplastic bone grafts was performed in the other two.The regenerate obtained was slowly corticalized in the first patient, submitted to various cycles of chemotherapy during the course of distraction. In the other two cases, which were not treated by chemotherapy during distraction, corticalization occurred over a shorter amount of time. Follow-up was obtained after 10 years in the first case, and after 2 years in the other 2 patients. There was no long-term recurrence.

5/9. Periosteal osteosarcoma with secondary bone marrow involvement: a case report.

    Periosteal osteosarcoma is an exceedingly rare type of chondroblastic osteosarcoma, showing a rather good prognosis, and secondary bone marrow involvement is unusual. However, there have been some reports describing periosteal sarcoma involving medullary bone. We encountered a patient, a 38-year-old man, who had a bone surface tumor in the left tibia. An X-ray showed an erosive cortical mass extraosseous portion, located in the diaphysis of the tibia. Other images revealed a thin cortex, periosteal reactions, coarse mineralization in the extraosseous portion, and bone marrow involvement. Grossly, surgical materials showed that the tumor mainly existed at the periosteal portion, only a part of the cortex was destroyed, and there was medullary involvement throughout. Histological examinations showed a predominantly chondroid component with malignant osteoid formation. On the basis of the histological macroscopic and microscopic findings, we made the diagnosis of periosteal osteosarcoma with secondary bone marrow involvement.

6/9. MR imaging of transarticular skip metastases from distal femoral osteosarcoma.

    We describe a case in which magnetic resonance (MR) imaging of a distal femoral osteosarcoma showed transarticular skip metastases in the proximal tibia. These lesions were not found by conventional radiography, bone scintigraphy, or CT. Since detection of transarticular skip metastases has an important influence on surgical management, MR imaging of metaphyseal osteosarcomas should always include the bone on the opposite side of the joint.

7/9. chondroblastoma of the upper end of the tibia, invading the attachment of the posterior cruciate ligament.

    A case of chondroblastoma with invasion of the joint via the attachment of the posterior cruciate ligament is reported. The importance of careful interpretation of early radiological signs and the usefulness of conventional tomographic and computerized axial tomographic examination is demonstrated, and a method for reconstruction of the defect using an AO buttress plate and bone chips is presented. There was no sign of recurrence two and a half years postoperatively.

8/9. Vascular reconstruction for limb salvage in soft tissue sarcomas.

    Ten patients with soft-tissue sarcomas of the lower extremity had involvement of major vessels, which were resected along with the surrounding tumor and muscles and replaced with vascular grafts. One of these patients had metastatic, unresectable disease and was operated on for palliation while three had resectable metastases and were included in the "curative" resection group. The resection involved the iliac vessels in three patients, the femoral vessels in six patients and the posterior tibial vessels in one patient. Ten arterial grafts were used--nine of them synthetic and one a reversed saphenous graft. Of six venous synthetic grafts, two remained patent for 3 and 4 months, while four clotted in the immediate postoperative period. Two of the patients have moderate swelling if they stand for a prolonged time, which is well controlled with elastic support. Of two infections, one involved the arterial graft and necessitated amputation. Adjuvant radiation was used in three patients and adjuvant chemotherapy in five patients. Three patients underwent chemotherapy for measurable metastatic disease. Of eight patients who underwent curative resection and successful arterial reconstruction, none has relapsed locally in a follow-up period ranging from 12 to 61 months (mean: 24.8 months). Six of the nine patients who underwent curative resection remain alive and well at 12 to 61 months (mean: 27 months). limb salvage for sarcomas of the extremities, which involves major vessel resection and reconstruction, is an effective method of treatment and is preferable to amputation.

9/9. Epithelioid sarcomas. Three cases.

    The authors present two cases of epithelioid sarcoma of the hand and one of the foot with clinical interest. This recently described tumor (Enzinger, 1970), is relatively rare. It occurs in the hand, forearm, pretibial region and foot and affects principally young adults. It should be emphasized, and this is borne out in the literature, that this tumor may appear perfectly benign and often has a course of long duration. The difficult of clinical and especially of histologic diagnosis as well as the difficulty of determining the boundaries of extension of the tumor makes it necessary to carry out radical surgery (amputation or rarely block excision). Every author agrees that local excision is to be condemned, there being an 85% recurrence rate. Spread of the tumor is by way of the fascial planes and tendon sheaths. Lymphatic and pulmonary metastases occur particularly when there is vascular invasion.
