The reported incidence of osteosarcoma of the foot varies between 0.2-2% of all osteosarcoma. Low grade osteosarcoma of the long bone represents only 1.9% of all osteosarcoma. A 38-year-old female had suffered painful mass in the proximal phalanx of the second toe for 1 year. Radiographic finding showed enlarged osteloytic mass which had penetrated thin cortex of the second toe and apparent increased uptake in bone scan was seen. Mass resection with autogenous bone graft using rib was performed. Histologically, the tumor was compatible with "low grade osteosarcoma". Second stage wide resection was performed. Because low grade osteosarcoma located in the proximal phalanx of the second toe is very rare, we report this unusual case with review of literature.

Pulmonary artery sarcoma is a rare disease and hard to diagnose; therefore, suspicion is very important for the diagnosis and treatment. Surgical resection is almost always needed because of progressive right heart failure. Adjuvant chemotherapy and radiation therapy are still controversial. We report a case of a 42-year-old man who had a right pulmonary arterial tumor Curative resection was impossible because the tumor invaded the left pulmonary artery. Palliative endarterectomy was performed followed by radiation therapy. The patient refused the chemotherapy. Until the postoperative 6th month, the residual tumor was stable. However, 15 months later, follow-up chest computed tomography revealed a metastatic pulmonary nodule at left lower lobe and the increased residual tumor. The patient received chemotherapy with limited tumor response. The metastatic nodule and residual tumor did not increase but bone scan revealed a rib metastasis at postoperative 24 months. He will be receiving additional chemotherapy.

Malignant schwannoma is rare tumor which is derived from schwas cells or nerve sheath cells, and it is frequently associated with Von Rechlinghausen's disease. We experienced one case of malignant schwannoma on the right chest wall without Von Rechlinghausen's disease. Patient was 64-year-old man who presented painless palpable mass on the right lower -chest wall for about 2 months. On chest computed tomography, the mass which was 6$\times$6 cm in size and had central necrosis, involved 11th rib with destruction, invaded the diaphragm and displaced the kidney anteriorlly. He underwent on-bloc resection of the tumor and discharged without any problem after 20 days.

Malignant flrous histiocytoma is a rare deep-seated pleomorphlc sarcoma, although its incidence Increasing. In this report, we present a case of a malignant fibrous histiocytoma, arising in the left chest wall in a 37-year-ol4 male patient. He underwent radical on bloc resection which include excision of tumor on left upper chest wall with resection of ribs from the first to third, left upper lo ectomy and chest wall reconstruction with Marled Mesh. However, he had local recurrence and distant metastasis within 12 months of the original operation. Malignant fibrous histiocytoma is an agrressive disease entity, with a propensity for early and distant spread.

다발성 골수증은 다양한 증세를 보이는 형질세포로부터 기원하는 악성종양으로 40세이상의 남성에서 호발되며 alkylating agent 단독, 혹은 corticosteroid와 병용하는 항암제 치료로 생존율이 크게 증가되기는 하였지만 치료후 평균생존기간의 20개월 내외로 완치율이 그다지 높지않은 형편이다. 악골에서의 발생은 극히 드물고 대개 늑골, 편평골, 척추, 골반, 두개골등에 광범위한 patchy destruction의 형태로 나타나는데 악골에 발생할 경우 임상증상은 장기적인 무통성 종창이 가장 흔하며 때로는 동통, 악골의 팽창, 감각이상, 치아의 동요, 악골골절등을 보이기도 한다. 전신적증상으로 무력감, 체중감소, 빈혈, 신부전, hypercalcemia, hyperiviscosity syndrome을 나타내기도 하는데 약 10%의 환자에서 전신적인 amyloidosis를 보인다. 진단은 골수생검상 골수의 plasmacytosis가 10% 이상이면서 혈장이나 뇨전기영동법에서 monoclonal globulin peak이 있을 때 가능하다. 여러 학자들은 처음에는 독립적인 고립성병소로 나타났다가 장기적으로 다발성골수종으로 이행됨을 주장하면서 장기적인 추적을 권하고 있지만 골내 고립성 형질세포종(solitary plasmacytoma in bone), 수질외 형질세포종(extramedullary plasmacytoma) 등은 다발성골수종과는 다른 질환이라 주장하는 등 아직 많은 논란이 있는 형편이다. 치료는 $4000{\sim}6000$ rad의 방사선치료와 여러 가지 약제의 복합적인 항암요법이 사용되고 있으며 국소적인 병소의 경우 외과적 절제술이 추천되기도 한다. 저자들은 59세 여자환자에서 하악골에 발생된 다발성골수종을 치험하였기에 문헌고찰과 함께 보고하는 바이다.

This is a report of 3 cases of tumors, which primarily originated from ribs and the sternum. In the first case of multiple myeloma, the patient was 67 year old male with a tumor located on the middle sternum invading the manubrium and the body of the sternum manifesting symptoms after a contusion of the anterior sternum. The sternum was entirely resected and was replaced by tantalum plate to reconstruct the defective chest wall in order to prevent the paradoxical movement during respiration. In the second case of osteogenic sarcoma, the patient was 43 year old male with a tumor located on the costochondral junction of the left 5th rib for 6 months. The left 5th rib was resected between the middle part and sternochondral junction of it including tumor and adjacent soft tissues. In the third case of chondrosarcoma, the patient was 36 year old male with a tumor located near the posterior angles of the right 7th and 8th ribs manifesting back pain on the area where the tumor was located. Resection of right lower lobe was performed since direct invasion of tumor was seen in the superior segment of right lower lobe. This was followed by the resection of both 7th and 8th ribs at the area between the costovertebral junction and the portion 10 em apart from the tumor including the tumor and intercostal soft tissues. Diagnoses of 3 cases of tumors described above were confirmed by histopathologic examination postoperatively. The postoperative courses were uneventful.

Purpose : This study was done to evaluate the efficacy of low-dose radiation in reduction of thoracic vertebral metastases in patients with breast cancer. Materials and Methods : 109 patients who were treated for bone metastasis from breast cancer from June, 1988 to June, 1998 in the Department of Therapeutic Radiology, Seoul National University were included. Of the 109 patients, 40 patients had been previously treated by postoperative radiotherapy and 69 had not. Postoperative radiotherapy had been given using Co-60 teletherapy device in 30 patients or 6 MV linear accelerator in 10. Thoracic spines from 1 to 10 were usually irradiated except in 1 patient and cervical vertebrae 6 and/or 7 were partially included in ,: patients. A total of 50.4 Gy was given with 1.8 Gy fraction. Metastatic bone diseases were scored in 11 regions, i. e., skull, conical spine, thoracic spine from 1 to 4, from 5 to 8, 9 and 10, 11 and 12, lumbar spine, pelvis, femur, ribs and others. Results : In no postoperative parasternal irradiation group, lumbar vertebrae were the most common metastatic sites $(55.1\%)$ followed by pelvis $(44.9\%)$, ribs $(40.6\%)$, thoracic vertebrae 11 and 12 $(37.7\%)$, thoracic vertebrae between 5 and 8 $(36.2\%)$, thoracic vertebrae 9 and 10 $(34.8\%)$, and thoracic vertebrae between 1 and 4 $(26.1\%)$. In postoperative parasternal irradiation group, lumbar vertebrae and pelvis were also the most common sites of metastases ($55.0\%$, respectively) followed by ribs $(37.5\%)$, and thoracic vertebrae 11 and 12 $(32.5\%)$. But significant less metastases were seen at thoracic vertebrae from 1 to 10. Conclusion : We can find that the were significantly less bony metastases at thoracic vertebrae which had been previously irradiated postoperatively.

Bone grafts are an integral and important aspect of craniofacial reconstruction. Ribs, tibia, and iliac bone have traditionally used as donor site but each of these has various problems, however using to the calvarial bone as a donor site has several advantage. These are as follows ; there are abundance of material, easy to reach the donor site through coronal incision, minimal pain of donor area, less functional inability, shorter hospitalization, no need of immobilization, hidden scar at donor site, no secondary deformity and appropriate curvature obtained properly selected. From march to December 1987, we experienced three cases of autogenous calvarial bone graft such as congenital saddle nose deformity, fibrous dysplasia on the right side frontal bone, and deviated nose. The results were very excellent without any significant complication. The detail technique of autogenous calvarial bone graft and its advantages compared with the traditional methods of bone grafts are discussed.

Fibrous dysplasia is a benign pathologic condition in which the normal cancellous bone is replaced by the fibro-osseous tissue. It is found mostly in the femur, tibia, skull, rib, and humerus. Clinically it may develops pain, progressive deformity, and pathologic fracture. Curettage with bone graft has been the most popular treatment method thesedays. A 17-year-old female who had fibrous dysplasia of the humerus combined with multiple cystic lesion was treated by intralesional steroid injection into the lesion total 2 times. The follow-up plain X-ray which was taken 11 months after steroid injection reveals decrease in size and increase in bone density and cortex thickness. The follow-up MRI reveals significant decrease in size and signal intensity. The signal intensity was decreased to that of normal bone marrow in T2 weighted image. She complains no pain and lives symptom free in last follow-up at 2 years and 8 months after steroid injection.

Background : This study examined the clinical utility of using indirect chest radiography during a physical examination of new conscripts for determine the presence of pulmonary tuberculosis. Methods : Over an eight-month period, this study examined 25386 people who underwent a physical examination after conscription. The abnormal findings on mass miniature radiography were followed-up using direct chest radiography. The positive predictive value of mass miniature radiography and direct chest radiography was compared. The incidence, degree of infiltration and clinical outcome of active pulmonary tuberculosis were also evaluated during a follow-up examination. Results : The positive rate of mass miniature radiography was 1.19% (n=302). Various lesions were identified: Parenchymal lesions (n=109), mediastinal lesions (n=6), cardiovascular lesions (n=45), pleural lesions (n=49), bony lesions (n=90) and miscellaneous lesions (n=7). The incidence of active pulmonary tuberculosis by mass miniature radiography was 0.26% (n=67). The first diagnosis was made in 50 people; active pulmonary tuberculosis (n=42), pneumonia (n=1), a mediastinal mass (n=1), a rib fracture (n=2) and a pneumothorax (n=4). Most cases of active pulmonary tuberculosis were mildly infiltrated and either improved or were cured by the follow-up examination. Conclusion : Although mass miniature radiography in a physical examination after conscription has limitations, but it is a useful means for detecting the presence of early disease, particularly in active pulmonary tuberculosis.
