Superior vena cava syndrome (SVCS) is rare in children. In Veterans General Hospital-Taipei, a total of 364 cases of SVC syndrome were diagnosed in the past 12 years. Of them only seven cases were younger than 18 years of age, ranging from 6 to 17 years, and they were all caused by mediastinal tumor. The underlying malignancy included malignant lymphoma in 4, teratocarcinoma in one and unknown in 2. The most common initial symptom was cough, followed in order of frequency by chest discomfort or neck mass. Dyspnea, orthopnea, swelling of head and neck, and venous engorgement might develop gradually within one to three weeks. Of the reported seven cases, two cases received immediate resuscitation upon arrival but expired in 1-2 hours. The other five cases received treatment with intravenous steroid as well as chemotherapy, and three cases also received committent emergent radiotherapy. Two of them expired 4 months and 2 years after treatment, respectively. Of the two surviving cases, one has received a complete course of chemotherapy and the other is still under regular chemotherapy in our hospital. Both of them are stable till now.

A 22-year-old woman was admitted to our hospital complaining of productive cough and dyspnea even at rest, and marked cervical lymphadenopathy. Marked stridor and orthopnea were observed, and auscultation of the chest revealed widespread expiratory wheeze which was not relieved by bronchodilators administered intravenously. Chest X-ray and CT scan revealed hilar lymphadenopathy and invasive tumor of the mediastinum. Bronchoscopy demonstrated narrowing of the trachea anteriorly and posteriorly and a submucosal nodular tumor protruding from the right anterior wall, causing approximately 90% occlusion of the lumen of the lower third of the trachea, but distal bronchi were intact. Microscopic findings of inguinal lymph node biopsy specimen revealed mixed cellular lymphoma compatible with Hodgkin's disease. Systemic chemotherapy resulted in relief of symptoms, and two months later, the endotracheal tumor had disappeared bronchoscopically, with slight residual stenosis of the trachea. Before treatment, pulmonary function tests indicated markedly impaired forced volume in 1 second in both expiratory and inspiratory cycles, especially in the latter phase. After remission, however, obstructive ventilatory dysfunction was observed. The cause of prolonged air flow obstruction was thought to be marked infiltration and almost total involvement of the tracheal wall by tumor with a nodular appearance of the lumen. Endotracheal tumor in Hodgkin's disease is rare, and there are few reports on pulmonary function associated with intrathoracic involvement of malignant lymphoma.

We report a case of rhabdomyosarcoma involving the mitral valve of a 57-year-old female. She was referred to our hospital for progressive orthopnea and edema. Chest X-ray showed marked cardiomegaly and pulmonary congestion. Echocardiogram revealed solid mass in left atrium involving the mitral valve. Emergency operation was required because of acute heart failure. At the operation, the mitral orifice was obstructed by the tumor arising from the left atrium. After partial resection of the left atrium, mitral valve replacement with a Carpentier-Edward prosthesis was performed. Subsequently microscopic examination diagnosed as rhabdomyosarcoma. She died three months after the operation of heart failure probably due to progression of the remnant of the tumor. This, to our knowledge, is the first case of mitral valve replacement for a primary rhabdomyosarcoma of the heart in Japan.

Autopsy or surgical specimens from six patients with primary cardiac angiosarcoma seen at the Mayo Clinic (all in men) between 1939 and 1988 were studied (patients' ages, 31 to 80 years; mean 50 years). The symptoms were nonspecific and included dyspnea and thoracoabdominal pain in six; anorexia in five; fatigue, hemoptysis, or orthopnea in four; nausea and vomiting, fever, or weight loss in three; and night sweats in two. Cardiomegaly was present in five, and a pericardial effusion or density, a mass adjacent to the heart, or nonspecific ST-T wave changes were present in three. All six neoplasms arose from the right atrium and exhibited epicardial or endocardial extension; three produced obstructive intracavitary right atrial masses. Pulmonary metastatic lesions were noted in five patients. The cardiac neoplasm was diagnosed by computed tomography or magnetic resonance imaging in the three most recent patients, and surgical resection was performed in two of them. Mean survival was 6 months after presentation. Causes of death were pulmonary hemorrhage in three, thoracic metastasis in two, and hemopericardium in one. The diagnosis of primary cardiac angiosarcoma was established at operation in two patients and at autopsy in four. Despite diagnosis by noninvasive imaging procedures and aggressive early surgical intervention, survival was less than 6 months. Thus optimal therapy is unclear.

A case of myxoid leiomyosarcoma located in the right pulmonary veins is presented. The patient complained of progressive dyspnea, orthopnea, sputum cruentum and right chest pain. Angiography revealed an obliteration of right pulmonary veins by a tumor mass that expanded into the left atrium. Histologically, the lesion contained densely packed fusiform cell areas that alternated with other much less cellular and richer in interstitial myxoid matrix. The tumor cells showed specific immunoreactivity to desmin antibodies and contained abundant thin filaments with focal densities and micropinocytic vesicles.

A 68-year-old woman, known to have a secundum atrial septal defect which had been asymptomatic, reported dyspnea and occasional chest pain for two years. Admission examination revealed orthopnea, cyanosis, polycythemia and inflow congestion of the upper part of the body. After some blood-letting, nifedipine and nitrates brought immediate relief of symptoms. Physical examination, chest x-ray and ECG were not different from previously known findings. All laboratory tests were normal. The findings on cross-sectional echocardiography raised the suspicion of a right ventricular tumor, which was then demonstrated by computed tomography. There were no metastases. Under extracorporeal circulation a right-ventricular benign myxoma, attached to the apical septum and the size of a tennis-ball, was removed. The postoperative course was without complications and the patient was discharged symptom-free.

This is a case report of a pheochromocytoma which developed in a 67-year-old man. The patient presented himself with a productive cough and orthopnea, both of which were subsequently proved to be due to hypertensive heart failure. The diagnosis of a pheochromocytoma originating from the left adrenal gland was established endocrinologically and roentgenologically. Transperitoneal adrenalectomy was undertaken, and a tumor weighing 300 g was obtained. Histopathologically, the tumor was composed of two elements: cells with profuse cytoplasma having chromaffin-positive granules, and other cells consisting of spindle cells with mitosis. Surgical exploration could not identify another tumor or metastasis, and his blood pressure returned to normal, with normal catecholamine levels, after surgery. This is the first reported case of an elderly person with a pheochromocytoma complicated by congestive heart failure and renal insufficiency preoperatively; however, it was controlled well, and he underwent surgery successfully. This case constitutes the 64th report on a pheochromocytoma in persons over 60 years of age in the Japanese literature.

A 64-year-old male with tracheal stenosis by thyroid cancer was scheduled for the emergency management of airway maintenance and total thyroidectomy. Dyspnea and orthopnea appeared suddenly on the admission for operation. Cervical CT and bronchial fiberscope examination revealed the trachea oppressed at the frontal neck by thyroid tumor. The trachea diameter was nearly 5 mm at the narrowest part. Therefore it seemed to be of high risk of perform tracheal intubation and tracheostomy. Extracorporeal circulation was adopted for the respiratory management at anesthesia induction. At first, the femoral artery and vein were cannulated with local anesthesia for cardiopulmonary bypass (CPB). After confirming CPB pump working, intravenous anesthetic agents were infused. Thyroid tumor was partially resected and tracheostomy was done under CPB. After the tracheostomy, a spiral tracheal tube was inserted. Anesthesia was maintained with sevoflurane and managed with controlled ventilation. Thereafter operation and anesthesia were uneventful. After the operation, pleural bloody effusion was noticed. Blood in effusion seemed to be due to the heparinization in extracorporeal circulation. We conclude that anesthetic management with extracorporeal circulation is one of useful methods for managing severe tracheal stenosis.

Mediastinal invasion with pericardial involvement in hepatocellular carcinoma (HCC) is rarely described. We report two patients with hepatitis-C-related HCC, who, after several courses of transcatheter arterial chemoembolization (TACE), developed mediastinal and pericardial neoplastic growth. Both patients presented with clinical manifestations of exertional dyspnea, chest pain and orthopnea. The diagnosis of HCC with pericardial involvement, through direct invasion of the anterior mediastinum, was established by computerized tomography and magnetic resonance imaging. These patients' symptoms were relieved after they received radiotherapy with a total dosage of 3,000 and 4,000 cGy over a three-week and four-week period, respectively. We suggest that direct mediastinal invasion with pericardial involvement should be considered when evaluating patients with advanced HCC who developed precordial distress following palliative TACE. Early recognition of this unusual complication is important in the management of HCC.

Two case reports of primary cardiac sarcoma, which is uncommon, are presented. The first case, a 38-year-old male, complained of chest tightness. Chest roentgenograms showed enlargement of the cardiac shadow and left pleural effusion. Transthoracic echocardiography and chest magnetic resonance imaging showed a tumor in the right atrium, and pericardial effusion. The tumor involved the right atrial wall and interatrial septum, and was partially resected. Pathohistological examination revealed angiosarcoma. He died 1 month later. The second case, a 19-year-old male complained of dyspnea and orthopnea. Chest roentgenograms showed pulmonary congestion. Transthoracic echocardiography showed a large mobile mass in the left atrium. An emergency operation was performed and the tumor was totally resected. Pathohistological examination demonstrated leiomyosarcoma. The postoperative course was uneventful, but the tumor rapidly recurred. Second and third operations were performed at intervals of 2 months. After the third operation, he was treated with radiotherapy. Local recurrence was not found but multiple distant metastases were found 2 months after completion of radiation therapy.
