Thoracic extramedullary hematopoiesis (EMH) is a rare disease entity that is usually associated with hematologic disorders, such as myelodysplastic or hemolytic disease. Because thoracic EMH is usually encountered as a mass during radiologic examinations, it should be differentiated from posterior mediastinal neurogenic tumors. Here, the authors report a case of EMH associated with hereditary spherocytosis. The patient underwent a complete excision by thoracoscopic surgery to differentiate it from other mediastinal tumors.

The granular cell tumor (GCT) occurs extremely rarely in the mediastinum. Few mediastinal GCT cases have been reported in Japan or other countries. Here, we report a case of a 24-year-old man with superior mediastinal GCT. The mass was located just above the aortic arch. It was firm, oval in shape, and well encapsulated. The tumor was removed completely with video-assisted thoracoscopic surgery, but we had to resect the vagus nerve, which was already included in the tumor, along with the tumor. After the operation, the patient recovered without any specific complications except for a mild degree of hoarseness.

Erdheim-Chester disease (ECD) is a form of non-Langerhans cell histiocytosis that most commonly involves the skeletal system. We report an unusual case of ECD presenting as an anterior mediastinal tumor without skeletal involvement. A 60-year-old man with no remarkable medical history was referred for evaluation of a mediastinal mass. The patient underwent surgical excision of the tumor via video-assisted thoracoscopic surgery. Histologic examination revealed marked proliferation of atypical histiocytes with sclerosis, and the results of immunohistochemical staining were suggestive of ECD.

Mediastinal tumors which are originated in mediastinum or probably metastasized from other organs have long fascinated the surgeon because of difficulty of diagnosis and treatment. This report is the analysis of the 26 cases of mediastinal tumors, experienced in the Department of the Thoracic and Cardiovascular Surgery, Chosun University Hospital from January 1978 to January 1985. The result are as follows; 1. The age distribution was 10 months to 68 years old and the average mean age was 34.7 years old. 2. Subjective symptom were as follows: Dyspnea [69.2%], Coughing [42.3%], Chest pain [30.8%], Back pain [15.4%] and Numbness of extremities [15.4%]. Objective signs were as follows: Decreased breathing sound [53.3%], Pleural effusion and hemothorax [34.6%], Palpable neck mass [34.6%], SVC Syndrome [19.4%] and Bloody sputum [15.4%]. But, there were no definitive symptoms in 2 cases. 3. The malignant tumors were 19 cases [73.1%]. 4. The germ cell tumors were 2 cases [7.7%], the neurogenic tumor were 3 cases [11.5%], lymphoma were 8 cases [30.8%], thymoma were 2 cases [7.7%], mesenchymal tumor was 1 case [3.8%], cyst was 1 case [3.8%] and carcinoma were 5 cases [19.2%] among the 23 cases, histologically analyzed. 5. The successful complete removal was done in 5 cases among 7 cases of benign tumors. In malignant cases, the surgical removal had been 7 cases and inoperable cases were treated to radiation and chemotherapy.

30례의 종격동 종양의 CT분석 결과, 저자들은 다음과 같이 요약 할 수 있었다. 1. 가장 흔한 종양은 흉선질환 이었으며, 그 다음으로는 기형종, 림프종, 기관지성 낭종, 신경종, 심막낭종의 순이었다. 2. 5례의 흉선종은 균일한 충실성 음영의 종괴로 보였으며, 석회침착, 소엽형성이 각각 1례에서 보였다. 악성흉선종 중 1례에서 피낭형성이 잘된 낭성 종괴로 보였으며, 흉선암종은 주위 경계의 소엽형성을 보인 균일한 음영의 종괴로 보였다. 3. 전 례의 가형종은 모두 낭성종괴로 보였으며, 지방과 석회음영은 각각 2례, 4례에서 보여졌다. 4. 신경종은 4례 모두에서 후종격동에 위치한 균일한 음영의 종괴로 보여졌다. 5. 기관지성 낭종은 기관분기부 하방, 부흉곽지역에 각각 1례, 후기관부에 2례 있었으며, 모두 균일한 음영의 낭성 종괴로 보여졌다. 6 심막낭종은 심장 주위 경계를 따라 난형모양의 낭성 종괴로 보여졌다. 결론적으로 종격동 종괴의 진단에 CT를 실시함으로써 종괴의 정확한 위치, 크기 및 특징적인 구성성분을 관찰할 수 있으며, 이러한 소견으로 종괴의 감별진단에 도움을 얻을 수 있다.

A 21 years old male student was admitted because of mediastinal mass that was noticed in routine physical examination. He complained progressive hoarseness, mild dysphagia, and anterior chest pain on deep respiration. This mediastinal mass was diagnosed as aortic aneurysm involving ascending, transverse, and descending thoracic aorta with aid of aortogram. Total prosthetic replacement of aneurysm was performed successfully using extracorporeal circulation and hypothermia. For myocardial protection during aortic cross clamping, cardioplegic solution was used and topical myocardial cooling was also adapted For simplicity of cardiopulmonary bypass, Y-shaped connectors took cerebral perfusion catheters to the main perfusion line beyond the arterial pump. Total bypass time was 219 minutes, and aortic cross clamp time was 104 minutes. Recovery was uneventful except respiratory insufficiency for first 4 days. Isotope aortogram checked on post operative 30th day showed normal aortic configuration. He was discharged on post operative 35th day. A follow-up chest X-ray study 5 months later showed nearly normal anatomy.

Carcinoid tumors of the thymus are vanishingly rare, and the characteristic cytologic findings of this condition have never before been reported in Korea. Recently, we encountered a 58-year-old woman who had been suffering from general weakness and weight loss for several months. Radiological imaging revealed a large anterior mediastinal mass. A fine needle aspiration biopsy (FNAB) of the mass showed predominantly scattered single cells, as well as some loose clusters of small cells with scanty cytoplasm. Some of these small cells exhibited plasmacytoid features, with moderately granular cytoplasm. We also discuss the cytological differential diagnosis between thymic carcinoid and other mediastinal tumors.

We report on a rare case involving a 23-year-old female patient with mediastinal cystic mass complicated with acute pericarditis and cardiac tamponade. Pericardial fluid demonstrated lymphocyte-predominant exudate and the level of carcinoembryonic antigen (CEA) was unexpectedly elevated. Successive aspiration of mediastinal cystic mass revealed a very high level of CEA (>100,000 U/mL) and carbohydrate antigen 19-9 (>15,000 ng/mL). This patient was clinically diagnosed as an infected bronchogenic cyst complicated with pericarditis and cardiac tamponade. The treatment resulted in alleviation of her symptoms.

The fibromatosis is a rare tumorous with local invasion, but is not metastasized distantly. This term should not be applied to nonspecific reactive fibrous proliferations that are part of an inflammatory process of are secondary to injury of hemorrhage and have no tendency toward growth or recurrence. It arises principally from the connnective tissue of muscle and overlying fascia or aponeurosis(musculaponeurotic fibromatosis), and chiefly affects the muscle of shoulder, pelvic girdle, and extremity. The term 'aggressive fibromatosis' is also employed to describe this disease, but it is impossible to predict the clinical course in the individual case. The fibromatosis arising in the mediastinum is very rare, and the report about it is nearly absent. The plain radiography shows merely mass with soft tissue density. The CT demonstrates a poorly defined homogenous or heterogenous mass, isodense with skeletal muscle on precontrast-images, and slightly hyperdense to muscle on postcontrast-scan. Accurate delineation between the tumor & surrounding tissue is vague or frequently impossible. The authors experienced one case of the mediastinal fibromatosis recently and report the case with review of concerned literature.
