Osteogenic sarcoma is the most common primary malignant tumor of bone in which tumor cells form neoplastic osteoid or bone or both. Classic osteogenic sarcoma usually involves the metaphysis of the more rapidly growing long bones (distal femur, proximal tibia). Osteogenic sarcoma of the foot is rarely noted and only a few well documented cases have been reported. Osteogenic sarcoma of foot can clinically, radiographically, and histologically mimic several benign lesions and tumor-like lesions, so it sometimes leads to late diagnosis and delayed treatment. We experienced a case of primary osteogenic sarcoma on left calcaneus in 66-years-old female and report it with a review of references.

Purpose: A 6-year-old boy with osteogenic sarcoma of the left humerus underwent bone scintigraphy. Tc-99m MDP was accumulated not only in the primary tumor but also in the osseous and extraosseous (pulmonary and pericardial) metastases. Osteogenic sarcoma directly produces osteoid, both in the primary and metastatic lesions. Tc-99m MDP is avidly taken up by tumor osteoid. At initial presentation, only 2% of cases have both pulmonary and osseous metastases. The patient had osseous, pulmonary, and pericardial metastases at presentation. This case presents that increased uptakes of Tc-99m MDP by the primary and metastatic tumor were demonstrated on bone scintigraphy at presentation.

Extraskeletal osteogenic sarcoma is a rare malignant tumor of soft tissue, and its predilection sites are the extremity, retroperitoneum, trunk, and the head and neck area. To our knowledge 5 cases of primary involvement of the mediastinum have been reported. Because of its rarity and difficulty in exact diagnosis preoperatively, we report an extraskeletal osteogenic sarcoma in the anterior mediastinum. The patient was a thirty eight old male. He complained of cough and sputum over 2 months. The chest roentgenogram and the chest MRI[magnetic resonance image] were done and showed anterior mediastinal mass with calcification. Excision of the mass was done under the preoperative impression of thymoma, and the pathologic report was extraskeletal osteogenic sarcoma of the mediastinum.

Primary tumors of the chest wall are rare than those of other portions of the body. Soft tissue tumors of the chest wall, though these are benign or malignant, should not be paid special attentions about their management than other soft tissue tumors of the body. Thoracic skeletal tumors, however, have some problems in the treatment because of defect in chest wall leading to herniation of lung and paradoxical movement of thoracic cage. The authors experienced 10 case of primary chest wall tumors at the department of thoracic and cardiovascular surgery, the national medical center, during last 15 years. Five of 10 cases were soft tissue tumors, and they were 2 case of lipoma and each one case of myxosarcoma and leiomyosarcoma. Among 5 bone tumors there no cases of sternal tumor, and their histopathological diagnosis were each one of fibrous dysplasia, giant cell tumor, osteochondroma, Ewing`s sarcoma and osteogenic sarcoma. Wide excision, though it was palliative one in certain case, was performed in 9 cases and only diagnostic incisional biopsy in one case, There were no postoperative deaths during admission to the hospital and all cases were missed during short term follow up after discharge from the hospital.

Osteogenic sarcoma is a malignant primary tumor of bone composed of a malignant connective tissue stroma with evidence of malignant osteoid, bone and/or cartilage formation. A 23year old man was admitted to dental department of Yeungnam University hospital with chief complaint of swelling and pain on alveolar ridge of lower right molar region. It was certain of osteogenic sarcoma through clinical and radiographic features and biopsy. Surgical resection of the lesion was performed by partial mandibulectomy and resin plate insertion. By follow up check of the patient, we made good result of functional reconstruction without any sign of recurrence of the lesion.

[ $^{99m}Tc$ ]-MDP bone scan was performed in 31 patients with primary malignant bone tumors, 22 patients with osteogenic sarcoma, 5 patients with chondrosarcoma and 4 patients with Ewing's sarcoma. The findings were classified by isotope intensity of accumulation in tumor as grade 1 to 3, overall pattern of isotope distribution in tumor as grade 1 to 3, and distortion of bony outline as grade 1 to 3. Histologic classifications were cor related with scan findings in 22 patients with osteogenic sarcoma. The results were as follows 1) In 22 patients with osteogenic sarcoma, markedly increased isotope intensity higher than sacroiliac joint with patchy areas of decreased intensity and severe bony distortion were found in 16 patients. The correlations between histologic classification and scan findings were not discovered. 2) In 5 patients with chondrosarcoma, mildly increased isotope Intensity with patchy areas of increased intensity and mild bony distortion were found in 4 patients.. 3) In 4 patients with Ewing's sarcoma, markedly increased homogenous intensity with moderate bony distortion were found in 3 patients. Conclusively there were common findings in each 3 primary malignant bone tumors and $^{99m}Tc$-MDP bone scan was complemented with radiologic studies in differentiating primary malignant bone tumors.

The estimated relative incidence of primary pulmonary sarcoma to lung cancer is 0.4%. Furthermore, osteogenic sarcoma of the pulmonary artery is extremely rare. We report a case of a 63-year-old woman who visited our emergency room with the chief complaints of chest pain, dyspnea and dizziness. On echocardiography, right heart failure due to acute pulmonary artery embolism was diagnosed and we performed emergency operation. After opening the main pulmonary artery trunk, we found a mass attached to the arterial wall and massive thrombi around the mass. The mass was diagnosed as primary pulmonary artery osteosarcoma through postoperative evaluation. The patient received chemotherapy and radiotherapy. The patient is alive without specific symptoms 16 months postoperatively.

Osteosarcoma is the most frequently encountered primary malignant tumor of the bone. But primary osteosarcoma of the skull(POS) is rare. The author presents a case of skull neoplasm identified as osteogenic sarcoma. A twentyseven-years-old male patient was admitted because of painful swelling at left temporal and zygomatic area with impairment of extraocular movement. Chest film and long bone series showed no evidence of abnormality. Skull films revealed round irregular bony destructive area at the left pterional area. CT and MRI revealed expansile destruction of the left sphenoid bone, lateral orbital wall and temporal bone within the hemorrhagic mass lesions which showed wall enhancement. Histologic examination confirmed a rare variant of osteosarcoma of the telangiectatic type.

Most clinicians have taken a lot of interest in tumors arising from the bony thorax because not only of their rarity and predictable diagnosis which could be reflected as a unique radiologic shadow but also variable surgical modes for maintenance of chest wall stability encountered after en-bloc resection. By the retrospective review, we have analyzed 24 cases of primary bony thorax tumors which were experienced and surgically treated at the St. Mary`s hospital of Catholic Medical College from Jan. 1969 to Sept. 1984. The results are as follows: 1. Age incidence was evenly distributed through all decades and the male-female ratio is 15:9. 2. 16 cases out of 24 were benign tumors and the commonest one of which was fibrous dysplasia. 3. Remaining 8 cases were malignant tumors and among which osteogenic sarcoma was the commonest one. 4. The majority of tumors [22/24] were developed from the rib and the remains were from the sternum. 5. Common manifestation were palpable mass or swelling and localized tenderness. 6. Various kinds of operative procedure were underwent: single resection of rib including tumor,14 cases; multiple resection of ribs with chemotherapy or myoplasty, 2 cases; en-bloc resection of the chest wall and reconstructive procedure, 5 cases; partial resection of sternum, 1 case; bone biopsy and chemotherapy, 2 cases.

Although primary surgical excision is the treatment of choice for the vast majority of patients with nasopharyngeal angiofibroma, radiation therapy is also employed as a primary tool or in the cases of tumor recurrence or massive intracranial extension. But, especially in young patients, postradiation sequelae such as osteomyelitis, atrophic rhinitis, thyroid or bone malignancy are of concern. Postirradiation osteosarcoma is a rare, but well-recognized complication of radiotherapy, which comprise roughly 2 to 5 percent of all osteogenic sarcoma. Recently we experienced a case of postirradiation osteosarcoma of the mandible who had treated by radiation therapy for the nasopharyngeal angiofibroma 30 years ago, presently he is ongoing chemotherapy and relatively being well.
