Osteosarcoma is a classical malignant bone-forming neoplasm which usually presents with an aggressive clinical course. The current case is presented with the radiographic feature of widening of the periodontal ligament space of the involved teeth, which is considered to be the earliest radiographic manifestation of osteosarcoma involving the jaw bone. The main aim of this case report was to focus on the importance of early diagnosis of this tumor based on clinical and radiographic examinations, and confirmation by histopathology. Considering the rarity of the disease type and particularly taking into account the fast progression and aggressiveness of this neoplasm, it is clear that the presentation of a clinical case represents a major contribution to better understanding of osteosarcomas involving the jaw bone.

Chondroblastoma is a rare benign cartilaginous neoplasm that accounts for 1% of bone tumors and is common in the epiphysis of the long bones. The condition is rarely found in the talus bone (4% of cases). This paper reports a 15-year-old male patient treated for a talus bone lesion discovered incidentally on imaging. Excisional biopsy, curettage, and an autobone and allobone graft were performed, with good results.

The Ewing`s sarcoma is the primary malignant bone tumor but the tumor also occurs as a primary soft tissue neoplasm without involvement of bone. Here is presented a case of extraskeletal Ewing`s sarcoma in the posterior and superior mediastinum with review of literature. To our knowledge, this is the first case report of extraskeletal Ewing`s sarcoma in Korea.

폐전이 골 연부조직 육종에 대한 폐절제 및 합병치료의 성적을 분석하였다. 1986년부터 1996년까지 14례 (남자 11례, 여자 3례)에서 15회의 폐절제술을 시행하였는데, 1례에서는 폐전이 육종의 재발로 2회의 폐절제술을 시행하였다. 절제된 폐전이 육종의 수는 1∼5개였다. 폐전이 육종의 병리조직학적 소견상 4례는 골육종 이었으며, 10례는 연부조직 육종이었다 폐절제술후 평균 생존기간은 29.2개월이었으며, Kaplan-Meier식에 의 한 5년생존율은 33.2%였다. 14례중 3례의 종양 자유기간이 3년이상으로 평균 생존기간은 52.6개월이었으며, 3년 이하의 11례는 추적기간중 모두 사망하여 이들의 평균 생존기간은 17.3개월이었다. 결론적으로 폐전이 육종에 대한 폐절제술은 뚜렷한 수명 연장 효과가 있을 것으로 생각된다.

Chondroblastoma is a rare benign bone tumor most frequently found in the epiphyseal region of long bones. The most common locations are the knee and proximal humerus,but the rib is an unusual site. Second decade is the most common age group. The ossification centers for the rib appear in the second fetal month and ossify in a caudal-to-cranial direction. There are also epiphyseal centers at the head and tubercle of the rib that appear at puberty and ossify in the third decade. The epiphyseal plates of the head and tubercle may be the site of origin of the posterior chondroblastomas; the anterior lesions may arise from the costochondral junction. The histologic features consist of polygonal chodroblast, small foci of chondroid production, osteoclast-like giant cell, and are diagnostic of chondroblastoma.We experienced a case of the chondroblastoma arising from the rib, and its clinical and histologic features are discussed.

The purpose of this study is to report a case in which neoplasm metastases of cervical vertebrae were found in lung cancer patient during inpatient treatment for neck pain. Pain assessment and physical examination including numeral rating scale, range of motion of neck, Spurling's test, cervical compression test were performed. As a result, C-spine series X-ray was taken under the judgement it is not a simple neck pain. Bone metastases were suspected as X-ray showed loss of C7 left pedicle, indistinct C7 left transverse process and indistinct C4 upper margin. Magnetic resonance imaging and computed tomography were taken as further examination, and metastases of C4, C6, C7 were confirmed. The patient was transferred for professional treatment. In conclusion, this study shows the importance of appropriate diagnostic evaluation such as pain assessment and physical examination, and the need for diagnostic imaging in the treatment of patients with neoplasm history.

Juvenile psammomatoid ossifying fibroma (JPOF) is a rare, benign, fibro-osseous variant of ossifying fibroma. It exhibits short-term rapid growth and has a high recurrence rate. Herein we describe a case of JPOF of the maxilla that was treated via complete excision utilizing an intraoral approach with immediate reconstruction using an iliac bone graft, in conjunction with a comprehensive review of the literature. A 20-year-old man presented with a mass on his right cheek that he reported had been growing over the last 10 months. In that cheek he had noticed fullness and experienced pressure, tenderness, and fluffiness, with no other ophthalmic or dental symptoms. After clinical, radiological, and histological examinations, the diagnosis was confirmed as JPOF. Surgical excision was performed, followed by immediate reconstruction with an autologous iliac cortical and cancellous bone graft harvested from the right iliac crest under general anesthesia. Good cicatrization of the intraoral surgical wounds and right iliac crest were evident. He was monitored for 6 months after the surgery and exhibited appropriate midfacial contour. There were no signs of recurrence or complications.

이 논문은 비소세포폐암으로 새로이 진단 받은 환자에서 수술 전 병기판정에 통상적으로 골 스캔의 유용성에 대하여 연구하였다. 대상 및 방법: 서울대병원에서 2000년 1월부터 12월까지 비소세포 폐암으로 진단 받은 환자 258명을 대상으로 하였다. 수술 전 병기는 과반수에서(132명) 수술이 불가능할 정도로 진행된 상태였다. 골 원격전이의 임상 평가 항목으로 증상, alkaline phosphatase, calcium 등을 채택하였고 모든 환자의 골 스캔 결과를 검토하여, 각각의 민감도, 특이도, 음성 예측률, 양성 예측률을 산출하였다. 최종적인 골 전이의 판단은 일반 X-lay나 MRI 또는 골 생검을 기준으로 하였다. 골 전이만 없다면 수술이 가능한 (“potentially operable”)환자 126명의 임상 경과를 따로 분석하여 수술 대상 환자에서 골 전이에 대한 임상 평가의 중요성을 검토하였다. 결과: 골 전이에 대한 골 스캔의 민감도는 96%, 특이도는 75% 양성 예측률은 44%, 음성 예측률은 99%였고, 골 스캔에 대한 임상 평가의 민감도, 특이도, 양성 예측률, 음성 예측률은 각각 54%, 73%, 54%, 72%였다. 골 전이에 대한 임상 평가의 경우는 80%, 70%, 38%, 94%였다. 골 전이만 배제하면 수술이 가능하였던 “potentially operable”군 환자 126명에서 골 전이에 대한 임상 평가의 음성 예측률은 99%였다. 결론: 폐암 진단 당시 병기 결정에 있어서, 골 전이에 대한 철저한 임상 평가가 필수적이다. 특히 골 전이 외에 다른 수술 불가능 요인이 없는 환자군에서 임상 평가 결과 특이사항이 없을 경우 골 전이의 확률이 매우 낮아, 통상적인 골 스캔 없이도 근치적 수술을 고려할 수 있음을 확인하였다. 그러나 임상 평가 결과 양성인 경우에는 약 30% 이상의 환자에서 골 전이가 발견되므로 골 전이를 발견하기 위한 골 스캔은 물론 다른 여러 가지 진단법을 적극적으로 검토해야 한다.

Metastatic thyroid carcinoma in bone shows characteristic expansile, trabeculated lysis on radio-gram. The ordinary scintigraphy manifests with a simple photopenic defect. We were able to portray trabeculation within photopenic defects. We present papillary thyroid carcinoma and follicular thyroid carcinoma, one each, pinhole bone scintigraphic findings of which are cold area with septated increased uptake at the iliae bone. These findings correspond very well with their X-ray pictures.

The loss of mandibular continuity due to trauma, neoplasm, or infection results in major esthetic and biologic compromise. The reconstruction of the mandibular bone defect still poses a challenge to oral and maxillofacial surgeons. There have been a number of variety graft materials. Among them, free block bone graft with rigid fixation has been widely used. However, cases using free block bone grafts may lead to a marked invasion of the donor site, mal-union, and absorption of the block bone. In this respect, particulate cortical bone using a titanium mesh tray can be an effective alternative option in order to achieve a proper bone contour and good oral rehabilitation. We have developed an intraoral approach for the mandibular reconstruction method using a titanium mesh tray with autogenous particulate cortical bone graft.
