A case of dedifferentiated liposarcoma in a fifty-one year old man is presented. The patient received a wide extirpation for a relatively rapidly growing mass in his right gluteal region. The mass was multinodular and consisted of two clearly distinct elements; well differentiated liposarcoma and non-lipogenic spindle cell sarcoma (fibrosarcoma). This is first proven case of dedifferentiated liposarcoma of the soft tissue in Korean literature, and its histogenesis is discussed along the dedifferentiation-redifferentiation pathway of fibrohistiocytic differentiation.

Treatment for the femoral shaft fractures in adolescents is somewhat controversial. These fractures have been treated nonoperatively, but adolescents tolerate prolonged immobilization less well than younger children and conservative treatment in this age group may result in more complicationssuch as malunion, shortening and angular deformities more often than those in the younger age group. Recently there has been a tendency to choose the operative method rather than traditional traction and casting technique for femoral shaft fractures in elderly children and adolescent The purpose of this study is to find better treatment for the femoral shaft fractures in adolescents. Fifty six femoral shaft fractures in 56 patients aged 10 to 14 years old were treated with traction followed by casting, open reduction and internal fixation with plate, closed intramedullary nailing, or external fixation using A-0 external fixator, and evaluated respectively for at least 1 year. External fixation may be benefit to patients with concomittant injuries and result in psychological settle down, early mobilization out of bed, short hospital stay, save of cost,and early return to daily living activities without any disadvantages such as malunion, leg length discrepancy or awareness of growing arrest in spite of negligible pin tract infection. Result of this study suggests that external fixation for the femoral shaft fractures may be an one of the attractive treatment option in adolescents.

Fractures of the tibial plateau involve a major weight-bearing joint, Thus, to achieve good joint function one must strive to achieve joint congruity, axial alignment, stability, and a satisfactory range of motion. Present operative treatment of tibial plateau fractures utilizes the principles of anatomical reduction, elevation of the plateau en masse, bone grafting of the defect in the metaphysis, stable internal fixation and early joint motion. Authors reviewed the 45 tibial plateau fractures operatively treated at Dong-Kang Hospital from Jan. 1983 to Dec. 1988 and analyzed the possible factors that could influence the results. Factors that may adversely affect the results were 1) old female. 2) Hohl Type VI, 3) delayed operation, 4) inadequate reduction, 5) no bone graft, 6) meniscectomy, 7) cruciate ligament injury, and 8) delayed exercise.

We obtained sixty normal chest postero-anterior(PA) radiographs with high kilovoltage technique(90-110kVp), 10 radiographs from the consecutive normal persons in each decade from twenties to seventies to analyze normal course and appearance of azygoesophageal recess (AER) line. (AER) line. CT scans from sixty consecutive normal persons were correlated with the radiographs to see how the line is formed and what structure the line abuts. In 20 patients with a lesion in AER area(10 with subcarinal lymphadenopathy of various size, five with left atrial enlargement, three with lesions in the esophagus, and two with dilated azygos vein), radiographic and CT correlation was done with main attention to the pattern of displacement of the azygoesophageal line. In normal chest PA radiographs, AER was shown as a straight line in young adults. As age increased, it was seen as a smooth are with convexity to the left. Sigmoid shape with midline cross was noted in an aged person. At the level of the right main bronchus on CT, AER was noted along the right lateral aspect to the vertebral margin in young adults. It extended medially as age increased. Caudally the recess extended more medially. The azygos vein usually bordered the recess. The esophagus or mediastinal fat sometimes bordered the recess in caudal level. In normal persons, the recess appeared deeper on plain radiographs than on CT. On plain radiographs, there were no changes in contour of AER with subcarinal lymphadenopathy of less than 2.5cm in diameter. However right sided and downward displacement of AER line just below the carina was noted with lymphadenopathy of more than 2.5cm in diameter. With left atrial enlargement, obliteration of the line was noted at T8-10 level. Focal right sided bulging of the line was noted with esophageal cancer Dilatation of azygos vein caused the line to appear with right sided displacement. In conclusion, AER line can be delineated with various features on radiographs with high KVP technique, depending on the age of normal persons and the formation of the line can be explained with CT. Displacement and change in the contour of the line can be seen with various mediastinal diseases.
