Ewing's sarcoma is a rare, but highly malignant bone tumor. During the years 1966-1983 we diagnosed and treated this tumor in 84 patients. Diagnosis of the tumor in an early stage is a prerequisite for successful therapy. Clinical and radiological findings contribute to the diagnosis, but histologic confirmation is indispensible. In addition to histomorphology we regard electron microscopy and the demonstration of glycogen as essential for the final diagnosis. The differential diagnosis includes haematogeneous
osteomyelitis
, malignant lymphoma,
metastases
from neuroblastomas, rhabdomyosarcoma and some benign bone tumors. New observations concerning the histogenesis of Ewing's sarcoma are discussed. The introduction of chemotherapy as part of a multimodality approach to treatment has substantially improved the prognosis in comparison to the previous results with surgery and radiation therapy. The role of surgery and radiation independently and in combination is discussed. We propose an approach to treatment based on our experience which involves surgical removal of the primary tumor after preoperative chemotherapy. The overall survival rate among our 84 patients was 40%. Among those who were diagnosed early and treated according to the recommended protocol 54% are alive.

Malignant change at the site of a chronic osteomyelitis, a rare condition, is reported in a 45-year-old man, along with a review of the literature. This patient with a 30-year history of chronic osteomyelitis of the right femur and an intermittently discharging sinus had a large abscess in the lower thigh. The abscess was drained, and an ulcer developed at the mouth of the sinus tract. Soon afterward, he sustained a pathologic fracture through the lower femur. Biopsy specimens of the ulcer showed a well-differentiated squamous carcinoma. An amputation was performed at the level of the proximal 10 cm of the femur. The patient remains well 18 months later with no clinical or radiologic evidence of
metastases
. Changes in character of a previously innocuous
osteomyelitis
sinus tract should arouse suspicion of neoplastic transformation. Biopsy of various depths of the sinus tract, including the bone marrow, is essential. Early amputation for squamous cell carcinoma is indicated and offers a good prognosis.

The effect of partial chest wall resection on subsequent production of spinal deformity was studied in six pediatric patients. The following observations are made: Scoliosis secondary to chest wall resection in the pediatric age group is progressive. The degree of curvature is related to the number of ribs resected. Anterior resection of ribs does not produce significant scoliosis, whereas resection of the posterior aspect of the ribs promptly produces scoliosis. Scoliosis associated with marked pleural thickening secondary to recurrent tumor, irradiation scarring, and underlying pulmonary
metastases
is always convex toward the normal side. Scoliosis associated with empyema and chest wall
osteomyelitis
is likewise convex toward the normal side and may respond to removal of this thether in the growing child.

Increased patellar uptake on bone scans is seen quite commonly but the possible or probable etiologies of this finding have not been previously well described. A review of 100 consecutive bone scans showed that the incidence of bilateral "hot" patellae is 15%. Identified etiologies include osteoarthritic degenerative disease (35%), fracture, possible
metastatic disease
, bursitis, Paget's disease, and
osteomyelitis
. The value of careful history, physical examination, and radiographs is stressed.

Although peripheral
metastases
of many malignancies to bone are common,
metastases
to the hand and carpus are rare. This is the first report of a silent primary malignancy of the lung presenting as a metastasis to the carpal navicular bone. Only eight instances of carpal bone metastases secondary to all tumor sources were revealed in a search of the literature. The presentation of
metastatic disease
in the hand in an occult malignancy may be deceptive, often mimicking pulp space infection,
osteomyelitis
, septic arthritis, gout, acute rheumatoid monoarticular arthritis, tenosynovitis, or sympathetic dystrophy. These lesions often present as radiolucent lesions; histologic findings are consistent with the tumor of origin. Treatment is palliative and consists of resection or amputation. Radiotherapy should be avoided in the hand due to secondary fibrosis and scarring.

The three-phase bone scan has been reported of value in the diagnosis of
osteomyelitis
. The use of a radionuclide angiogram, an immediate postinjection "blood pool" image, and 2 to 3 hour delayed image have been useful in separating nonosseous inflammatory disease from
osteomyelitis
. However, dependence on increased blood flow and focal hyperemia for this diagnosis may limit the use of the study if other processes are shown to produce similar results. To identify limitations of the three-phase bone scan we studied 14 patients with metastatic bone disease and nine patients with Paget's disease. Blood flow results showed no increase in three of 14 patients with
metastases
, intermediate increase in seven of 14 patients with
metastases
and two of nine patients with Paget's, and intense increase in four of 14 patients with
metastases
and seven of nine patients with Paget's. All patients showed increased focal activity in the immediate "blood pool" and delayed images. We conclude that because of increased flow Paget's disease may be difficult to separate from
osteomyelitis
. However,
metastatic disease
can often be differentiated on the basis of quantitative focal hyperemia. The three-phase bone scan remains of value in the diagnosis of
osteomyelitis
, but other diseases of bone must be included in the differential diagnosis.

Percutaneous needle biopsy was performed in 20 patients who had radiologic abnormalities after irradiation of the skeleton. The biopsies were performed to determine the nature of the bone changes and to differentiate radiation necrosis from
metastases
or local tumor extension. Eleven patients had tumors, two of which were radiation-induced sarcomas; nine patients did not show evidence of tumor. One patient had
osteomyelitis
rather than the suspected tumor. The value of percutaneous needle biopsy in the postirradiated skeleton is discussed.

The unique opportunity to study the entire appendicular skeleton of a child who died from metastatic angiosarcoma allowed detailed assessment of radiographically evident involvement. Virtually every portion of the appendicular skeleton had evidence of
metastatic disease
. However, the extent of involvement was extremely variable, especially when contralateral regions were assessed. The most likely region of metastasis, the metaphysis, is normally a fenestrated cortex of woven bone in the young child, rather than a well demarcated cortex formed by osteon (lamellar) bone, as it is in the adult. The pattern of destruction is such that less extensive areas may be involved before becoming radiographically evident, and trabecular bone involvement may be evident even without cortical damage. The metaphyseal metastatic spread supports the concept of arterial hematogenous dissemination, comparable to
osteomyelitis
in the child. Pathologic metaphyseal fractures involved both proximal humeri; the fracture also extended along a portion of the metaphyseal-physeal interface in one humerus. In one distal femur the physis readily separated from the metaphysis; this was a non-displaced type 1 growth mechanism injury.

Regional osseous blood flow (OBF) to various regions of the femur and tibia was measured using radioactively labeled 15-micrometers microspheres injected into the right atrium of neonatal, skeletally immature, and skeletally mature canines. Each bone was divided into as many as 41 anatomically distinct sections to assess developmental and regional comparisons in OBF. A quantitative decrease in OBF with increasing chondro-osseous maturity was observed for both the whole bones as well as many regions within a given bone. This was particularly significant in the tibia in which OBF to the mature tibia was much lower than in the immature tibia or even the mature femur. In the immature and neonatal bones, the epiphyseal and metaphyseal regions nearest the physes had the highest flow. The physis had a statistically significant high flow rate. Furthermore, regional differences in OBF correlated well with known regional functions in both endochondral and membranous (periosteal) bone formation. OBF tended to be greater in regions of greater metabolic activity associated with hematopoiesis and endochondral osteogenesis. OBF values correlated well with regional predilections of various diseases such as acute hematogenous
osteomyelitis
prior to skeletal maturity and osseous
metastases
, and, by extrapolation, strongly support a physiological reason for delayed healing and nonunion in tibial fractures in the skeletally mature human.

Destructive bone lesions in long bones associated with onion like periosteal reaction was found in two girls. Diagnosis of Ewing sarcoma was followed by bone biopsy which indicated eosinophilic granuloma. The radiological appearances of
osteomyelitis
, tuberculosis, congenital syphilis, Caffey's disease and
metastases
of neuroblastoma are similar. Bone biopsy is mandatory for correct diagnosis.
