This 32 year old female patient underwent left radical mastectomy due to ductal carcinoma on May 1990, and treated with FAM (5-fluorouracil, Adriamycin and Mitomycin C) regimen postoperatively. However, right cervical Iymph node enlargement and facial edema progressively developed since December 199). On April 1994, operation was performed, and findings were as followes; x4$\times$5$\times$7 to 1 : 1 $\times$ 1 cm sized multiple enlarged and hyperemic Iymph nodes were scatterred throughout submandibular area to the junction of superior vents cave and pericardium, and partially invaded both anterior segmental lobe, sternum and both distal tip of clavicles. After radical dissection of the nodes of neck and mediastinal nodes, and wedge resection of both anterior segments of lung, and partial resection of both clavicle tips and total sternum. The both innominate veins and superior vena cava were partially obstructed by invaded cancer SVC reconstruction was done with preclotted 10$\times$ 10$\times$ 18mm Y shap d woven Dacron graft, which was anastomosed to the point of the junction of subclavian vein and jugular vein after cross clamping both veins and 2cm above the pericardial junction with one arm clamp. After maintaining blood drainage to the SVC from the right side, left innominate vein was anastomosed with 4-0 Prolene continuous running suture. Bone cement was used for resected sternal portion and clavicular ends were fixed to postal portion with 18 Gauge wires. The patient was treated with radiation and chemotherapy after discharge, and there were no evidence of regrowing of the mass nor obstruction of the graft inspite of no antithrombotic therapy.

The fat-forming variant of solitary fibrous tumors (SFTs) is a rare soft tissue neoplasm that was previously referred to as a lipomatous hemangiopericytoma (L-HPC). The most common affected site is deep soft tissue. Here, we present the first case, worldwide, of a fat-forming variant of SFT of the pleura. A 74-year-old man presented with left lower chest pain. Chest radiographs showed a mass-like lesion at the left lower lung field and chest computed tomography revealed a 12 cm fat-containing enhancing mass that was well-separated, lobulated and inhomogeneous. Radiology findings suggested a liposarcoma. Percutaneous needle biopsy was performed and pathological diagnosis of the mass was a fat-forming variant of SFT. Surgical resection was carried out and there has been no recurrence to date. So, a benign fat-forming variant of SFT must be considered as one of the differential diagnoses of lipomatous tumors of the pleura.

Background: Although the lung is a common site of metastasis, endobronchial metastases (EBM) from extrathoracic malignancies are rare. Previous studies were retrospective reviews of the cases from each single institute, and the last one was performed between 1992 and 2002. We evaluated the characteristics of patients with EBM who had been diagnosed in recent 10 years in our hospital. Methods: We retrospectively reviewed 1,275 patients who had undergone diagnostic bronchoscopic procedures between 2001 and 2011. An EBM was defined as bronchoscopically notable lesion, which was histopathologically identical to the primary tumor. Results: A total of 18 cases of EBM were identified. The mean age was 53 years, and 12 cases of the 18 patients were female. The most common primary malignancies were colorectal cancer and breast cancer (4 cases each), followed by cervix cancer (3 cases) and renal cell carcinoma (2 cases). Cough was the most common symptom. The most common radiologic finding was atelectasis, which was identified in 27.7% of the cases. The median interval from the diagnosis of primary malignancy to the diagnosis of EBM was 14 months (range, 0-112 months). The median survival time from the diagnosis of EBM was 10 months (range, 1-39 months). Conclusion: EBM from extrathoracic malignancies were rare. Colorectal cancer and breast cancer were common as primary malignancies. Fiberoptic bronchoscopy should be performed in all patients, who are suspected of having EBM. If atypical clinical and pathological features are present, appropriate diagnostic studies should be undertaken.

Objectives: Minimal improvement in the long-term survival of head and neck cancer(HNC) patients has occurred despite a multitude of advances in the control of loco regional disease and a second primary malignancy(SPM) contribute to the continued poor prognosis for the HNC patients. This study was performed in order to identify the clinical characteristics of SPM in the HNC patients. Materials and Methods: The medical records of 354 patients of head and neck squamous cell carcinoma that were followed up after initial treatment during the period of 1987 through 1994 were reviewed. This study examines the medical records of 354 patients with squamous cell carcinoma of the head and neck, of whom 26 subsequently developed a second neoplasm. Results: The actuarial SPM rate was 7.3%, and median time to presentation for the SPM was 26.8 months. The SPM were more likely to occur in male patients who had oral cavity index tumors. Patient whose index tumor was small at diagnosis had a greater chance of developing a second tumor as did those with no cervical lymph node metastases to the neck. Initial treatment modality was not associated with an increased risk of developing a second tumor. The commonest sites for the SPM were the lung and other head and neck area. The 3-year survival for patients who developed a secondary tumor from the time of its diagnosis was 27.8%. Conclusion: The SPM in the head and neck cancer patients are not uncommon and early detection of the SPM will contribute to increase the long-term survival of HNC patients.

Multiple bone metastases are common manifestation of many malignant tumors such as lung cancer, breast cancer, prostate cancer and renal cell carcinoma. Bone metastasis is secondary cancer in the bone, and it can lead to bone pain, fracture, and instability of the weight bearing bones, all of which may profoundly reduce physical activity and life quality. Treatment for bone metastasis is determined by multiple factors including pathology, performance status, involved site, and neurologic status. Treatment strategies for bone metastasis are analgesics, surgery, chemotherapy and radiotherapy. External beam radiotherapy has traditionally been an effective palliative treatment for localized painful bone metastasis. However, in some cases such as multiple bone metastases, especially osteoblastic bone metastasis originated from breast or prostate cancer, the radiopharmaceutical therapy using $^{89}Sr$, $^{186}Re$, $^{188}Re$, $^{153}Sm$ and $^{117m}Sn$ are also useful treatment option because of administrative simplicity (injection), few side effects, low risk of radiation exposure and high response rate. This article offers a concise explanation of the radiopharmaceutical therapy for multiple bone metastases.

Paraganglioma is a neoplasm consisting of sympathetic neuroendocrine cells, which arise from neural ectoderm of extra-adrenal paraganglia. It often occurs in thyroid, carotid body, mediastinum, lung, duodenum, the retroperitoneal area and periaortic area. Malignant paraganglioma is defined not by the histological diagnosis, but by spread to regional lymph nodes or distant metastasis. Rare bone metastasis mostly occurs in the base of skull or spine, and even it rarely metastasizes to pelvis or femur. We would like to report two cases of paraganglioma; one in the subcutaneous fat layer that was mistaken for a vascular tumor, and the other in the retroperitoneal space with early bone metastasis.

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.

Hamartoma is rare but the most common benign neoplasm in the lung. However endobronchial lipomatous hamartoma has been rarely reported. A 73-year-old male patient was admitted to our hospital due to hemoptysis 1 month prior to admission. On bronchoscopic examination, a large pedunculated endobronchial mass right upper lobar bronchus. The endobronchial mass was enucleated by bronchotomy that is no evidence of malignancy in frozen specimens. We report a case of endobronchial lipomartous hamartoma which was resected by bronchotomy.

Background and Objectives：Peripheral nerve sheath tumors(PNSTs) are uncommon neoplasm in the head and neck region. The treatment of PNSTs is surgical removal, but excision cause neurologic complications. This study was performed to evaluate the proper diagnosis and treatment of PNSTs with our experiences. Subjects and Method：During the period from October 1994 to July 2007, 58 patients were diagonised with PNSTs in head and neck region. We reviewed medical records and imaging study retrospectively. Result：95%(55/58) of the PNSTs in head and neck were benign；5%(3/58) were malignant peripheralnerve sheath tumors(MPNSTs). 63%(37/58) were neurilemoma, 20%(17/20) were neurofibroma, 2%(1/58) was perineuroma. 55 patients underwent surgery. 80%(45/55) of cases were treated with excision. Enucleation was performed in 7(14%) patients. All cases of benign neurogenic tumors showed no recurrence. Among 3 of MPNSTs 2 patients were Von Recklinghausen’s disease and expired with regional recurrence and lung metastasis. Conclusion：The benign PNSTs can be treated with enucleation if possible and observation can be another choice to minimize neurologic sequele.

Thyroid carcinoma is relatively rare in children. Eight cases of thyroid carcinoma were among 18 patients operated upon for thyroid tumors at Pediatric Surgery, Asan Medical Center in 11 years' period between 1989 and 2000. Five patients were boys and three were girls. The age distribution ranged from 10 to 14 years with a median age of 11.6 years. We studied clinical presentations, diagnostic workup, pathology, treatment, and follow-up (recurrence, mortality, and survival). All patients presented with anterior neck mass but one with multiple cervical lymph nodes enlargement. Familial history of thyroid cancer was seen in one case. All patients had a cold nodule by 1-131 thyroid scan. Fine needle aspiration (FNA) biopsy was performed in all patients. The right lobe was involved in four patients and the left lobe in two. Two had both lobes involvement. Pathologically, six cases were papillary carcinoma, one was follicular carcinoma, and one insular carcinoma. Four patients underwent unilateral lobectomy and isthmectomy. Total thyroidectomy was performed in three patients. The insular carcinoma case was preoperatively diagnosed as follicular neoplasm by FNA. After confirmation of the pathology by initial right thyroid lobectomy, total thyroidectomy was subsequently done. Cervical lymph node metastases were presented in three cases (37.5%), and lung metastasis in two cases (25%). Three patients received postoperative I-131 ablation. After a median follow-up of 53 months, all patients were alive without evidence of recurrence. In conclusion, thyroid carcinoma in children is frequently associated with lymph nodes involvement and distant metastasis, however, the prognosis is relatively good.
