Chordoma is relatively uncommon tumor comprising $1\sim4%$ of primary malignant bone tumors, and believed to arise from the remnants of notochordal tissue. Because of its rare occurrence in the thoracic spine, we report a case of chordoma involving the thoracic spine. A 45-year-old male was sufferred from chest pain radiating to the back. Chest CT showed a well marginated, round huge mass with multiseptated enhancement at the thoracic spine from T5 to T8 level. After percutaneous needle aspiration, piecemeal resection of the tumor was done. On cytologic smears, two types of neoplastic cells were arranged in sheets and cords in mucinous background. One type of cells consisted of medium sized cells with pink cytoplasm and round nuclei. The other type had voluminous bubbly or clear cytoplasm divided by intracytoplasmic septae imparting a feathery or basket-like appearance. Histologically, the tumor showed lobulated feature divided by fibrous septae and the tumor cells were pink eosinophilic or physaliphorous in morphology. Immunohistochemically, the tumor cells revealed strong positivity for low(AE1) and high (AE3) molecular weight cytokeratins.

Pulmonary aspergillosis is the most common disease of fungal infection and has lower infectivity. Pulmonary asergillosis is classified by aspergilloma, bronchopulmonary aspergillosis, necrotic and invasive aspergillosis. Invasive aspergillosis is found in immune compromised host, immunosuppressive treatment after organ transplantation, anticancerous chemotherapy, blood abnormality, AIDS patients etc. We reported a case of invasive aspergillosis in an immunocompetent host, with review of literatures.

We experienced a case of giant cell tumor arising from the right 2nd rib in the diagnostic and therapeutic thoracotomy at our department of Thoracic and Cardiovascular Surgery, Chungnam Univ. Hospital in May 3rd, 1991. The reports of this tumor are very rare and are known to have the incidence of 1 percent or less of all giant cell bone tumor. The tumor of the right 2nd rib, infant head-sized, covered with parietal pleura was invaded into the vertebra on operation finding. The tumor was resected partially[three fourths] and revealed to be the giant cell tumor on pathologic finding. At now, the patient is taking the radiotherapy to achieve the therapeutic goal to the remnant tumor.

A 22 year old soldier was discovered on routine study for discharge to have a mass in the posterior mediastinum He was admitted due to high fever and improved by antibiotic treatment for 2 weeks. Chest PA, apicogram, myelogram and CT scan demonstrated enlargement of the neural foramen at the T1 level with erosion of the posterior aspect of the vertebral body and the pedicle contiguous with the intrathoracic mass, A myelogram showed a large extradural defect at the T1 level on the left. There were no clinical signs of cord compression. A standard posterolateral thoracotomy incision was made with extension to high thoracic vertebra. The 3rd rib was resected and the angles of the posterior portion of 1st and 2nd ribs were cut and rib heads were removed. Extrapleural neurilemmoma 6x6 cm was resected intrathoracically. And after removal of the pedicle and the lamina, intraspinal extradural mass 3 X 2 cm was resected carefully with trivial tearing of the dura which was sealed with gel-foam and pleura. There was ma postoperative neurological complication.

Adrenal metastasis from papillary thyroid carcinoma is extremely rare. We present herein a patient with adrenal metastases from recurrent papillary carcinoma of the thyroid. A 54 year-old woman had received a total thyroidectomy and postoperative radioactive iodine therapy for locally advanced papillary thyroid carcinoma. One year after initial surgery, distant metastases to multiple organs including right cervical lymph nodes, left upper lung, left 2nd and 3rd ribs, 2nd thoracic vertebra and left adrenal gland were found by 18-FDG-PET-CT whole body scan. She underwent right modified neck dissection, partial resection of left 2nd and 3rd ribs, posterior arch of 2nd thoracic vertebra, left upper lobectomy of lung, and left adrenalectomy. On histologic examination, metastases to the left adrenal gland and cervical lymph nodes were papillary thyroid carcinomas, while other metastatic sites turned out to be anaplastic thyroid carcinomas. Despite aggressive surgery and postoperative adjuvant therapy, her general clinical conditions were getting worse day by day due to regrowing of the anaplastic thyroid carcinomas. To our knowledge, this is the first case reported in Korea.

The relationship of cartilage canals to initial osteogenesis of primary ossification center of developing vertebrae in human fetuses ranging from 50mm to 260mm in crown rump length was studied by light and electron microscopy. The cartiage canals of the thoracic vertebrae were first observed at 60mm fetus. Cartilage canals were identified as vascular channels arising from perichondrium surfaces. A number of cartilage canals were observed around the primary center of ossification at 80mm fetus. At 120mm fetus, cartilage canals of the bodies of vertebra were increased. Eventually the canals were eroded from the main medullary cavity and remained at only peripheral regions of growth cartilage. Superficial, intermediate, and deep canals were identified by the characteristics of cartilage cells. Fibroblasts, undifferentiated mesenchymal cells, and vacuolated macrophages were observed adjacent to the matrix of resting cartilage cells in the superficial canal. Fibroblasts and mesenchymal cells were densely packed at the tip of canal, giving an epithelial appearance to the clustered cell in the intermediate canal. Vacuolated macrophages were in contact with matrix of hypertrophied cartilage. The thick-walled vessels in the intermediate and deep canals consisted of typical endothelial cells, but in the newly formed vessels contained mesenchymal cells and fibroblasts incorporated into the vessel wall. During lengthening of cartilage canal, the matrix of cartilage cells were invaded by newly formed capillaries and vacuolated macrophages. At the deep canal, the lateral wall of the canal terminated in matrix containing calcified cartilage. The mesenchymal cells began to differentiate into osteoblasts adjacent to the calcified matrix. The results indicate that the connective tissue cells within the cartilage canals proliferate and differentiate into osteoblasts at the site of primary ossification center.

The clinical studies were performed on 301 cases who took Yongkakkyo-tang from June 1993 to December 1994 The results were as follows: 1. About 80%(239 cases) patients who took Yongkakkyo-tang were improved. 2. The ratio of male to female patients was 106:133. In the age distribution, it was found that under 20's were 8%(24/301), 30's and 40's were 33%(98/301), and over 50's was 39%(117/301). 3. In the regional distribution, it was found that Cervical region was 22 cases, thoracic region was 12 cases, cervical & lumbar region complex was 50 cases, upper limbs region was 6 cases, lower limbs region was 12 cases, and lumbar region was 153 cases(64%). 4. Among improved cases, the cases treated only with Yongkakkyo-tang were 16(5%), the cases treated with Yongkakkyo-tang, and treated with Chiropractic were 19(6%), the cases treated with Yongkakkyo-tang and Yanggun-tang chiropratic were 133(44%). 5. Among improved cases, the number of Chiropractic treatment, less then 15 teimes were 69 cases, 15 to 30 times were 91cases. Basedon these results, it was shown that Yongkakkyo-tang could be used for the treatment of degenerative disease of vertebra, and the treatment with Yongkakkyo-tang, Yanggun-tang and Chiropratic is more effective.

A 7-year-old, intact female Korean Jindo dog was referred due to ataxia and pain on palpation of the thorax. Radiograph, echocardiography and computed tomogram revealed a mass on the heart base region and osteolytic change of fifth thoracic (T5) vertebra. At necropsy, a firm, encapsulated and round mass was seen arising from the heart base region surrounding the ascending aorta and pulmonary artery. Histopathologically, nests of cuboidal and polyhedral cells having abundantly granular and eosinophilic cytoplasm with round to oval nucleus were separated by fibrous septa. Immunohistochemistry using chromogranin A revealed that tumor cells were originated from neuroendocrine organ and metastasized into some organs including lung, spleen, liver, kidney and T5 vertebra. By electron microscopy, we found the electron-dense and membrane-bound granules in cytoplasm of the tumor cells. This study provides the uncommon evidence that aortic body tumor metastasized to both multiple organs and bone.

The congenital tracheoesophageal fistula without atresia of the esophagus is considered a rare variant, and the literature concerned to the tracheoesophageal fistula without atresia, is little in adult especially. The 22-year-old male was admitted to Yeungnam University Hospital with his chief complaints of weight loss (6kg/6 months), abdominal discomfort, and intermittent coughing. The diagnosis was made by the endoscopy and esophagography. The fistula was 1.5cm in diameter, 0.5cm in length. The level was around second thoracic vertebra. The operation was performed transpleurally through the right third intercostal space and the fistula was secured with interrupted silk suture after division. The fibrotic adhesion was seen around the tracheoesophageal fistula. The postoperative course was uneventful, and postoperative esophagogram revealed ho extraluminal leakage. Herewith we report this unusual case of isolated tracheo-esophageal fistula with review of literatures.

SAPHO syndrome is an acronym for an increasingly recognized syndrome of synovitis, acne, pustulosis, hyperostosis, and osteitis. Most of the previously reported case are from Japan and Europe. The authors report a case of SAPHO syndrome in Korean female who presented with extrasternal neurologic symptoms. A 60-year-old female with thoracic and right chest wall pain presented with the sternocostoclavicular hyperostosis, and recurrent aseptic osteitis. Previously, she had hystrectomy and thyroidectomy due to uterine malignancy 25 years ago. Also, she started to take medications for palm and sole pustulosis 7 days prior to admission. Through evaluation of clinical, radiological, serological studies, studies was done along with bone needle biopsy for the biological reassessment. The hyperostosis was found in the pedicles of thoracic 8, 9, 10 vertebrae and sternoclavicular joint. Radio-isotope bone scan showed an accumulation of tracer in thoracic vertebra. The bone biopsy from these site showed increased osseous turnover, thickening of trabeculae accompanied by mild acculuation of granulation tissue and round cell infiltration, compatible with mild chronic inflammation with marrow fibrosis. The patient showed good response to conservative management. The authors report a case of SAPHO syndrome with thoracic radiculopathy. It is considered that SAPHO syndrome is related to spondyloarthropathy, and appears to have benign disease process with good prognosis.
