A 70-year-old male was admitted with complaints of anterior chest pain and tumor formation. He has a history of pulmonary tuberculosis and was performed artificial pneumothorax therapy 37 years ago. The diagnosis on admission was perforation of empyema cavity into the chest wall. But thoracotomy revealed that the chest tumor arising from chronic empyema wall was a malignant lymphoma. Decortication and extirpation of the tumor were performed with combined partial resection of chest wall. Immunohistological examination showed that the histology was diffuse large T cell type of Non-Hodgkin's malignant lymphoma. The patient has been alive and well for 24 months postoperatively.

Benign teratoma of the mediastinum causes a variety of complications if left untreated, but reports of pericardial perforation have been rare. We report a case of mediastinal teratoma that perforated the pericardium and induced clinical cardiac tamponade. The patient was a 46-year-old male, who was admitted due to sudden chest pain. Since chest CT and echocardiography suggested perforation of the pericardium by a mediastinal teratoma, pericardial drainage was carried out. However, heart failure could not be resolved, and the tumor was resected on the 5th hospital day. From the intraoperative and pathologic findings, mature type mediastinal teratoma was found to have perforated the pericardium, causing massive influx of yellowish fluid from the cyst of the tumor. There have been only 10 cases reported to date in Japan and abroad in which mediastinal teratoma was complicated by cardiac tamponade.

A 59 year-old housewife was admitted to the emergency service with a sudden onset of chest pain and nausea. Initially she was treated as an acute myocardial infarction, but conventional treatments were not effective, and she was sent to our hospital for further evaluation. Her ECG showed several abnormal findings including T-wave inversion, atrial flutter, QT-time prolongation, ST-segment depression or elevation, and frequent ventricular ectopic beats. The echocardiogram, 201thallium scintigram and coronary angiography were almost normal. Both urinary and plasma levels of catecholamines were remarkably increased, and the plasma epinephrine was extremely high during attacks. Abdominal echotomography and CT-scanning showed a large left adrenal tumor. The 131MIBG scintiscan revealed a high accumulation in this tumor. Then the patient was diagnosed as having pheochromocytoma and catecholamine-induced myocarditis. The administration of phentolamine (10 mg) normalized the inversion of T-wave and the high blood pressure. But when propranolol (2 mg) was administrated in addition to phentolamine, the ECG showed a biphasic low T-wave change. According to these phenomena, we supposed that the alpha-adrenergic receptor was involved in the development of the ST-T changes of the ECG, and the alpha-adrenergic receptor of this patient might be sensitive under excessive catecholamines, according to the inhibition of the beta-receptor by propranolol.

A 30-year-old man had a history of smoking 1-2 packs per week for 10 years. He had suffered from a productive cough with whitish mucoid sputum for two months. Left anterior chest pain, palpitation and shortness of breath developed about two weeks before his admission. Chest radiographs showed collapse of the left lower lobe. Bronchoscopy revealed a strawberry-like tumor on the left main bronchus with nearly complete obstruction. Pathology showed bronchial squamous papilloma with surface dysplasia, but no evidence of malignancy. The obstructed lumen was completely reopened by bronchoscopic Nd-YAG laser therapy. Unfortunately, the tumor recurred two months later. Therefore a sleeve resection of the tumor was performed six months after the laser photoresection. After two years of follow-up, no evidence of tumor recurrence has been found.

Cavernous hemangioma of the heart is a very rare disease. A 57-year-old male patient was admitted due to frequent onset of dull chest pain, which had been occurring for about 1 year. The pain was not related to exercise and was not relieved with nitroglycerin. On echocardiographic examination, a tumor was shown in the outflow tract of the right ventricle and was confirmed with computer tomography. He underwent open heart surgery for resection of the tumor. After a median sternotomy and opening of the pericardial cavity, a reddish-brown-colored tumor, 3 cm in diameter, was found protruding from the epicardial layer of the right ventricular outflow tract. The tumor involved all layers of the ventricle and could be resected only with the help of the cardiopulmonary bypass technique. The defect in the right ventricle was repaired with a woven dacron patch. The patient recovered without incident after the operation, and experienced no chest pain during 7 months of follow-up. Histology showed it to be a cavernous hemangioma.

Endobronchial neoplastic disease is rarely encountered in patients under 20 years of age. The great majority of these lesions are carcinoids or mucoepidermoid carcinoma. Symptoms are secondary to bronchial irritation and manifest as recurrent pneumonitis, hemoptysis, persistent cough, reactive airway disease, and chest pain. Early bronchoscopy reliably enables identification and may prevent harmful sequelae resulting from delay in diagnosis. Retrospective data from four cases collected from the Tumor Registry in the Southern California Kaiser Permanente Medical Group is presented and a review of the literature is discussed.

A 61-year-old man was admitted to our hospital with cough, bloody sputum, and chest pain. Bronchoscopy showed a tumor in the truncus intermedius which biopsy and brushing cytology revealed to be squamous cell carcinoma. Also, bronchial washings grew only N. asteroides. Treatment with minocycline and trimethoprimsulfamethoxazole (TMP/SMX) over one month resulted in some improvement in pulmonary symptoms and resolution of the infiltrates in the right lower field. Then, right pneumonectomy was performed. N. asteroides was isolated from the resected tumor. Aggressive bacteriological examinations should be utilized when the possibility of pulmonary nocardiosis is considered.

A 54-year old patient was admitted to the hospital with chest pain, dyspnea and left-sided pleural effusion, which was confirmed by a radiograph of the chest. In view of an exposure to asbestosis a CT scan of the chest was performed, which showed pleural thickening. The suspected diagnosis of a malignant mesothelioma was confirmed by needle biopsy of a paraaortic lymph node. Because of the existence of metastases a palliative pleurectomy was performed. Histologically a malignant mesothelioma of the biphasic type was found. The patient died less than half a year later from local progression of the tumor.

A 46-year-old man was admitted with complaints of fever, cough and anterior chest pain. Chest X-ray examination disclosed an infiltrative shadow in the right upper lung field and chest CT scan strongly suggested invasion of mediastinum and anterior chest wall. Therefore, steroid therapy was selected because biopsy specimen showed proliferation of fibroblasts and mononuclear cells mainly containing plasma cells with no evidence of malignancy. After steroid therapy, chest X-ray examination showed that the infiltrative shadow was greatly reduced. However, since infiltrative shadow was increased again at 3 years after the initiation of steroid therapy, right upper lobectomy was performed. Histopathological analysis of resected tumor demonstrated proliferation of mature plasma cells and fibroblasts in conjunction with minor infiltration of neutrophils and lymphocytes. At 18 months after operation, new shadows appeared in right S8 and S10 which were shown to have almost the same histological findings as the resected tumor. Steroid therapy was restarted, and then the size of shadows decreased. It is conceivable that steroid therapy is an effective therapy for pulmonary plasma cell granuloma, especially multifocal and relapsing cases.

Pleural mesotheliomas are uncommon tumors that can be classified as localized or diffuse. Diffuse pleural mesotheliomas are invariably malignant. Although the frequency is low in the general population, it is more common in persons with a heavy occupational exposure to asbestos, and is considered as a signal tumor to asbestos exposure with medicolegal consequences. Mesothelioma incidence has been steadily rising during the past two decades, reflecting the increase in asbestos exposure during and following World War II. Clinical features include initial complaints of nonpleuritic chest pain and dyspnea. Distinguishing malignant mesothelioma from metastatic adenocarcinoma can be difficult, and can require large tissue biopsy with special stains and electron microscopy. The median survival of about 9 to 12 months confirms the poor outcome of pleural mesothelioma. The clinical deterioration is primarily attributable to locoregional spread of tumors, but metastasis is not rare. Several factors seem to have a prognostic value: performance status, stage, platelet count, age, histologic subtype, and asbestos exposure. In spite of the different therapeutic modalities such as surgery, radiotherapy, and chemotherapy used alone or in combination, the median survival is fairly different from survival among untreated patients. Because of the uncommon occurrence of this tumor and the existence of several different prognostic categories, a cooperative effort will be necessary for future therapeutic trials. If these active new therapies are identified, it would be useful to compare them to a best supportive care regimen in order to demonstrate an advantage of the treatment.
