Hemipelvectomy was performed in 50 patients with malignant neoplasms of the upper part of the thigh and pelvis. Although not technically difficult, the operation is associated with considerable blood loss. Postoperative complications are frequent, the greatest morbidity resulting from skin flap necrosis. Symptomatic phantom limb is as occasional late problem. Of 37 patients resected for cure prior to 1969, 14 were alive five or more years postoperatively. Five of these long-term survivors subsequently died of metastases. Patients with fibrosarcoma and chondrosarcoma had the best survival. Six other patients underwent palliative hemipelvectomy for intractable pain, with gratifying results. Hemipelvectomy is an important, useful operative procedure in selected patients.

Nine cases of untreatable tumour in which radical surgery was employed palliatively are presented. Three hemipelvectomies for recurrent rhabdomyosarcoma were performed. In one case, death occurred postoperatively, probably as a result of pulmonary embolism. One patient survived for 8 months, while the other is still alive after three years. Of two cases in which interscapulothoracic disarticulation was performed, survivals of 9 and 5 months were observed in subjects with fibrosarcoma in a mastectomy site and recurrent sarcoma of the humerus with ling metastases. Survival to 7 months was obtained in a case of sarcoma of the maxilla, while three patients with squama cell cancer of the mouth floor, chondrosarcoma of the mandible and botryoid sarcoma of the tonsillar fossa are still living after periods of 10 months to 2 yr. Though devoid of schematic indications, palliative demolition surgery can be considered in borderline cases where the operative risk is not high. Irrespective of "quantity", the "quality" of life remaining to the patients can be made compatible with the psychophysiological limits of the human personality.

In about 10% of patients suffering from multiple osteochondroma a malignant degeneration of one osteochondroma occurs. Data of 59 patients are collected from the literature. The malignant degeneration occurs at the age of 31 in average, mostly on the pelvic girdle, less frequently on the shoulder girdle and on the ribs. The development is slow in most cases, at times interrupted. The first clinical signs are an increase in swelling, rarely pain or neurological symptoms. Radiological findings and prognosis correspond well with those of a proliferative chondroma or a primary chondrosarcoma. Recurrences after local treatment are frequent, metastases are rarely found. Regular check-ups and good information of patients suffering from multiple osteochondroma are recommended.

The authors report three cases of bone tumours, two in the scapula and one in the pelvis, which simulated chondrosarcoma on radiological examination. After biopsy it was concluded that they were metastases secondary to carcinoma of the bladder in one case and of unknown origin in the other two.

A patient with bronchogenic carcinoma with a solitary metastases to the femur in whom the clinical, radiologic, and pathologic setting suggested that the primary tumor was the bone lesion (chondrosarcoma) and the pulmonary lesion was a solitary metastasis is presented. This case is added to the limited literature indicating that mucin-secreting tumors metastatic to bone may simulate primary bone tumors radiographically.

A mixed malignant tumour of the lung intermediate in type between pulmonary blastoma and carcinosarcoma is described. The epithelial component consisted of squamous carcinoma, undifferentiated carcinoma, and clefts lined by bland epithelial cells. The supporting stroma was composed of pleomorphic sarcoma, fibrosarcoma, chondrosarcoma, osteosarcoma, and indeterminate mesenchymal tissue. The tumour was removed surgically, but the patient died postoperatively with rapidly developing multiple bony and soft tissue metastases. Subcutaneous metastases showed the appearnce of poorly differentiated pleomorphic sarcoma. Published reports of mixed malignant lung tumours are reviewed.

The present investigation endeavors to characterize the mucosubstance content of 170 myxoid and chondromatous tumors and chordomas by histochemical methods. The results obtained using the critical electrolyte concentration (CEC) method as introduced by Scott and co-workers23,24 were compared with those obtained by staining with alcian blue and toluidine blue at different pH's with and without pretreatment with bovine testicular hyaluronidase. Tissues known biochemically to contain different heteroglycans were used as controls: synovial fluid and cock's comb (hyaluronic acid) stained with alcian blue up to a MgCl2 concentration of 0.1 M; fetal cartilage (chondroitin 4- and 6-sulphate) pulposus with notochordal remnants (keratan sulphate) up 10 1.0 M. The staining reaction of intramuscular myxoma and myxoid liposarcoma corresponded to that of synovial fluid and cock's comb (containing hyaluronic acid). Benign chondromatous tumors (osteochondroma, enchondroma, extraskeletal chondroma, chondromatosis in bursae, synovia, and tendon) as well as well-differentiated chondrosarcomas had a similar staining reaction to that of adult cartilage (containing keratan sulphate). However, the intensity of the reaction was lower in these tumors than in the adult cartilage, indicating that the keratan sulphate content of the tumors is lower. Most of the moderately well-differentiated chondrosarcomas, the poorly differentiated chondrosarcomas, and pulmonary metastases of chondrosarcoma, as well as mesenchymal chondrosarcoma and extra-skeletal chondrosarcoma possessed the same staining properties as fetal cartilage, known to contain chondroitin 4- and 6-sulphate but not keratan sulphate. A few of the moderately well-differentiated chondrosarcomas stained up to a MgCl2 concentration of 1.0 M. Three cases of poorly differentiated chondrosarcomas stained with alcian blue up to 0.35-0.45 M in the lowest differentiated areas, indicating the presence of sulphated heteroglycans, as chondroitin 4- and 6-sulphate. Most chordomas possessed the same staining properties as fetal cartilage; however, a few chordomas stained in the same way as notochordal remnants of nucleus pulposus (containing keratan sulphate), which are thought to be the origin of these tumors. The results of staining of the tumors in the present series with the Scott technique corresponds well with toluidine blue and alcian blue at different pH's with and without pretreatment of the sections with testicular hyaluronidase. Since bone and soft tissue tumors may contain varying mucosubstances depending on the tissue of origin and on differentiation, histochemical investigation of the heteroglycan content of these tumors may be a valuable diagnostic aid.

An accurate pathological diagnosis must be made prior to treatment of a primary malignant bone tumour. Consideration must be given to the clinical and radiologic aspects as well as the histology. Both benign and malignant tumours occur more frequently in certain decades. A search should be made for precursor lesions such as Paget's disease. The presenting manifestations of pain, a mass and dysfunction are not specific for tumours. Laboratory tests may be helpful, especially in distinguishing tumours from infections and metabolic diseases. Metastasis is usually via the blood stream to the lungs and bones. The low survival rate following amputation for osteosarcoma and radiation therapy for Ewing's sarcoma has been improved by chemotherapy. The lower-grade tumours such as aggressive giant cell tumour and low-grade chondrosarcoma can often by treated successfully by resection and insertion of an autograft, an allograft or a metallic implant.

Chondrosarcoma is a malignant tumor that arises from cartilage. In the maxillary area, the tumors spread locally but may also invade blood vessels and metastasize systemically. Initial surgical resection is the treatment of choice.

The clinical course and the results of radiographic and histological investigations in three patients with dedifferentiated chondrosarcoma are presented. The tumors were characterized by chondrosarcomatous tumor sections of low grade malignancy adjacent to fibrosarcomatous tissue sections. One to two and one-half year after the onset of the first clinical symptoms pulmonary metastases appeared and in one case a subcutaneous mass presented, which had the histological appearance of a fibrosarcoma. Differentiation of a chondrosarcoma customarily has an adverse effect on the prognosis with both the early appearance of metastases and a rapidly fatal clinical course. Cartilagenous tumors of the axial skeleton and the long bones must be extirpated surgically in an early and radical fashion, particularly if there are radiographic signs of proliferation.
