Synovial sarcoma is a malignant soft tissue tumor originated from the primitive mesencymal cell. It occurs primarily in the extremities, especially in the lower extremities. Primary pulmonary synovial sarcoma has been rarely reported in literatures. We experienced a case of intrapulmonary synovial sarcoma with brain metastasis which originated from the lung.

Background & Methods : In order to measure the acute and subacute toxicity of Vermilionum and it's anti-cancer effects, Sarcoma-180 abdominal cancer cells were injected intravenously. The following results were obtained after measuring the survival rate, toxicity of the NK cells, and IL- 2 productivity. Results : 1. It was impossible to measure $LD_{50}$ value in the acute toxicity test and no toxic effects were witnessed in the clinical observation. 2. No significant differences were shown in the weight changes between the experiment groups and the control group in the acute toxicity test. 3. No peculiar toxic effects were shown in the subacute toxicity test and the weight changes were insignificant between the experiment groups and the control group. 4. In measuring the survival rate after inducing abdominal cancer by Sarcoma-180, the experiment groups showed increased of 9.52% compared to the control group. 5. In measuring the activity of NK cells, no significant changes were shown between the experiment groups and the control group. 6. In measuring the productivity of IL-2, significant reduction was shown in the experiment groups compared to the normal group, but no significance was witnessed compared to the control group.

Undifferentiated pleomorphic sarcoma (UPS) is a high-grade neoplasm that is usually located in the extremities and retroperitoneum. In the past, UPS was considered the most common soft tissue sarcoma in adults; due to improvements in diagnostic techniques, most cases have been reclassified as other lineage-specific tumors. Gnathic bones are rarely affected, and the clinicopathological characteristics of this neoplasm when diagnosed in the jaw remain to be better described. In this report, we present a rare case of mandibular UPS affecting an 88-year-old female who demonstrated a painful swelling on the right side of the mandible that was accompanied by a pathological fracture. Microscopic examination revealed a pleomorphic spindle-cell neoplasm with mitotic figures and necrosis. The patient underwent surgery and adjuvant radiotherapy but experienced metastasis after 12 months of follow-up and died. Diagnosis of UPS is challenging, and oral pathologists must be aware of this entity when dealing with aggressive undifferentiated neoplasms.

흉통을 주소로 내원한 34세 남자 환자에서 흉부 컴퓨터 단층촬영상 좌측 흥부에 종괴와 흉막수가 발견되었다. 개흉술을 실시하여 벽측늑막에서 기원된 종괴를 제거하였으며 종괴는 저분화 활막육종으로 진단되었다. 벽측늑막에서 기원한 활막육종은 드문 질환으로 저자들은 이를 치험하였기에 보고하는 바이다.

Ewing sarcoma in the head and neck is rare, and metastasis from other bones to the mandible accounts for 0.7% of cases. This report presents a case of oral metastasis in a 24-year-old male patient diagnosed with Ewing sarcoma of the femur (p53 gene mutation and EWSR1-ERG fusion). The chief complaint was numbness in the mandible and pain for 1 month and a hardened, ulcerated exophytic lesion in the right retromolar region. Imaging exams revealed an unspecified thinning of the cortical bone of the inferior alveolar canal in the right mandibular ramus, associated with erosion of the alveolar bone. Histopathological analysis confirmed metastasis of Ewing sarcoma. The patient presented an aggressive disease progression and died 1 month after the oral diagnosis. It is important to recognize the signs and symptoms compatible with rare clinical outcomes, leading to an early diagnosis that can improve patients' quality of life and survival.

Ewing`s sarcoma is a highly malignant tumor which occurs most frequently in the diaphysis of the long bones, although any bone may be involved. Ewing`s sarcomas occurring in the rib are rare. Recently, we experienced one case of Ewing`s sarcoma which arose in the right second rib in a young female patient. She was treated with three principal treatment modalities-en bloc excision of chest wall followed by radiation therapy and chemotherapy. Clinical course is described with review of related literatures.

Primary sarcomas of the pulmonary arteries are and the clinical presentation closely resembles several more common conditions, Therefore they are seldomly diagnosed preoperatively without a pathologic esxamination of sufficient surgical specimen. Treatment of these tumors remains primarily surgical as possible and the role of the adjuvant chemotherapy and radiotherapy is not yet evident We report a case of primary sarcoma of pulmonary artery clinically suspected of carcinoid partially involving the pulmonary parechyme and the bronchus mainly in the left main pulmonary artery and the vein with left intrapericardial pneumonectomy.

Epithelioid sarcoma is a rare tumor which is usually presented with a nontender nodule on a distal extremity. It is sometimes confused with granulomatous process or chronic inflammation. We report of a case of epithelioid sarcoma on a foot of an adult male, which progressed rapidly.

Epithelioid sarcoma is a malignant soft tissue neoplasm with an uncertain histogenesis. We report the imprint cytologic features of epithelioid sarcoma in the left shoulder of a 29-year-old male patient. Imprint cytologic findings showed dissociated and loose aggregates of anaplastic epithelioid cells on the necrotic, bloody, and inflammatory background. Tumor cells were round to polygonal shaped. Tumor cells had vesicular nuclei with abundant cytoplasm. The nuclei were irregular in shape and often eccentrically located. Some tumor cells were oval to spindle shaped. Binucleated and multinucleated cells were found. Intracytoplasmic vacuoles were present. On immunohistochemical stain, the tumor cells were positive for epithelial membrane antigen, vimentin, and CD34.

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.
