악성 간엽종은 유아와 태생기에서 매우 드문 종양이다. 악성간엽종은 성인에서 극히 드물고 섬유조직이외의 둘 또는 그 이상의 간엽성분으로 구성된 종양으로 결체조직의 어떤 형태로도 분화할 가능성이 있는 태생기 간엽에서 기원한다고 생각된다. 환자는 61세 남자로 2개월 전 가래를 동반한 기침을 주소로 검사를 받던 중 우폐상부에 매우 큰 종괴를 보이는 암종으로 입원하였다. 환자는 우폐상부 미세침윤조직검사상 편평상피세포암 의심하에 우전폐절제술을 받았다. 수술장 소견상 종괴는 흉벽과 심하게 유착되었으며 우폐하부까지 침습된 소견을 보이는 악성간엽종으로 진단되었다. 환자는 수술후 5,000rad의 방사선 조사를 받고 수술후 6개월째인 현재까지 재발징후없이 경과 관찰중이다.

The malignant germ cell tumor found in the gonad can originate in the anterior mediastinum. Endodermal sinus tumor[Yolk sac tumor] is a kind of malignant germ cell tumor and is derived from extra-embryonic mesoderm. We experienced a case of primary mediastinal endodermal sinus tumor occurred in 22 year old male patient. His chief complaint was anterior chest pain for 2 days. The tumor located in the anterior mediastinum and invaded upper lobe of the deft lung and pericardium. A left upper lobe resection including phrenic nerve and pericardium was performed and the tumor in the anterior mediastinum was excised. The patient has been treated with combination chemotherapy[Cis-platinum, Vincristine, Actinomycin-D, & Cyclophosphamide} and followed up for 4 months with partial remission.

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.

Tumors of the mediastinum are usually classified according to their location in the anterior, middle, or posterior mediastinum. Mediastinal teratomas are characteristically located at anterior mediastinum with only rare incidence in the posterior mediastinum. Two cases of posterior mediastinal teratoma were experienced recently, in the department of thoracic surgery, Seoul National University Hospital. The incidence of posterior mediastinal teratoma was 4.2% among 48 mediastinal teratomas in our experience. Two cases are all benign teratoma located at right posterior costophrenic angle, and histologically showed tissues from three germ layers including bone and fat.

The cavernous hemangioma often occur on the skin and mucosal surfaces of the body, but are also found in many viscera, particularly the liver, spleen, pancreas and occasionally in the brain. But it is rarely encountered in the mediastinum, but when found occur predominantly in the anterior mediastinum. It can occur in any age and have no characteristic symptoms or roentgenographic findings including angiocardiography. Inspite of its histologic benignancy, it may be locally invasive and can result in rib erosion or adjacent structural compression. Usually, surgical exploration is not only the sole means of assuring a diagnosis and the only treatment. Recently, we experienced one case of cavernous hemangioma in the anterior mediastinum, which was removed surgically, being proved to be cavernous hemangioma on histologic examination. Related literatures were reviewed.

Hemangioendothelioma is a rare vascular tumor with involvement of the liver, brain, long bones, and lung. Among the 6 histological subtypes, epithelioid hemangioendothelioma (EHE) is the most aggressive. Its occurrence in the mediastinum is quite rare, and very few cases have been documented. The reported cases in the literature have described difficulties in the preoperative diagnosis due to the unusual histological appearance of the tumor. Immunohistochemistry remains the mainstay for a definitive diagnosis. Due to its low incidence, there is no standard treatment for mediastinal EHE, but curative resection is the preferred treatment option where possible, with chemotherapy used as an adjuvant treatment or in cases of widespread inoperable disease. The present case study describes an aggressive EHE occurring in an 18-year-old woman in the anterior mediastinum.

Thymoma is a common anterior mediastinal mass, although thymomas have occasionally been found in the neck, pulmonary hillus, or posterior mediastinum. But a thymoma within the middle mediastinum has rarely been reported. We report a thymoma arising in the middle mediastinum with a review of the literature.

Calcifying fibrous pseudotumors are rare soft-tissue lesions pathologically characterized by hyalinized collagen, psam-momatous or dystrophic calcification, and lympho-plasmacyte infiltration. They are clinically benign with an extremely low rate of recurrence and complete surgical resection is known to be the treatment of choice. We performed the resection of a calcifying fibrous pseudotumors in the anterior mediastinum without complications.

A case of nonfunctioning paraganglioma of the anterior mediastinum in a 64-year-old woman is presented. The tumor was adherent to the pericardium and parietal pleura but not to the phrenic nerve. Complete excision of the tumor is the treatment of choice, but partial excision may provide long-term survival. A new classification and terminology suggested by Glenner and Grimley is emphasized. This aorticopulmonary paraganglioma is the first case in the Korea.

원발성 전 종격동 종양은 종격동 종양의 반이상을 차지하고 그 종류도 다양하다. 흉선 상피 종양이 가장 흔하고 악성 흉선종은 드물다. 생식세포종은 두 번째로 흔한 전 종격동 종양으로 보다 어린나이에 발생하며 대부분 양성이다. 임파종은 대부분 전신성 질환의 흉부 침습 형태로 나타나나 원발성 흉부 임파종은 Hodgkin씨 병이 많다. 저자는 대표적인 전종격동 종양의 임상증상과 영상의학적 소견을 소개한다.
