[A case report of the limited form Wegener's granulomatosis].

The classical from of Wegener's granulomatosis (WG) is a necrotizing granulomatous angiitis that involves the upper and lower airways, and kidneys. A limited form of WG is characterized by pulmonary lesions identical to those of classical form WG without renal involvement. The authors report a case of limited form WG. A 58-year-old Japanese woman was admitted because of an abnormal pulmonary shadow. Pathological examination revealed granulomatous angiitis consistent with WG. No other organ involvement was found. The pulmonary shadow improved with cyclophosphamide therapy. The patient is now well and without evidence of exacerbation of the disease 18 month after the discharge.

[A case of tuberculous osteomyelitis resembling metastatic cancer on bone scintigraphy].

A 48-year-old male was referred to our division, on the suspicion of lung cancer with bone metastasis. Chest radiography showed a mass shadow and bone scintigram demonstrated multiple scattered regions of increased uptake. However bronchial and bone biopsy specimens revealed granuloma with epithelial cells and giant cells. A diagnosis of tuberculous osteomyelitis was made, and antituberculous therapy was begun. Chest radiography and bone scintigrams one year later showed marked improvement.

[A case of miliary tuberculosis associated with ARDS, DIC and bilateral pneumothorax].

We reported a case of 64 a year-old male patient of miliary tuberculosis associated with ARDS, DIC and pneumothorax, who had a history of gastric ulcer and pulmonary tuberculosis. On admission his chief complaints were fever, fatigue, palpitation, appetite loss and weight loss, and most noticeable abnormalities were bleeding from the gastric ulcer and miliary shadow on the chest x-ray film with hypoxemia. On the day after admission to the hospital he was diagnosed as ARDS as he showed severe hypoxemia due to extensive tuberculous infiltration in bilateral lung fields, and treatment with antituberculous drugs and steroids were started. On the third hospital day DIC appeared on laboratory data, Gabexate mesilate (FOY) for DIC and respirator for ARDS were introduced. Two weeks later pulmonary infiltration, PaO2 and general condition were somewhat improved. On the 15th day after admission pneumothorax occurred on the right side, and on the 20th day on the left. Tube drainage of both pleural cavities, and instillation of OK-432 and Fibrinogen HT into the right pleural cavity were done, but it showed no effect. Two months after admission pouring Fibrinogen HT and thrombin into the left B1+2 and right B1 with cannula washing pipe through the instrument channel of bronchoscope was carried out. A few days later air leakage stopped and collapsed lungs were completely expanded. This method is effective in the case of incurable pneumothorax with pulmonary hypofunction.

[Right ventricle support after lung resection].

It is very important to establish a method of determining the influence of lung resection on right ventricular function and to devise some therapeutic methods of supporting the right ventricle. However, there has been no systematic research on these issues. We found that echocardiographic demonstrated abnormal motion of the ventricular septum after right pneumonectomy and of the left ventricular wall after left pneumonectomy. We developed a triggered cuirass respirator and showed that it could support the right heart after a lung resection. We also found that the injection of SF6 Gas into the postpneumonectomy pleural space might be useful in supporting the right heart after a pneumonectomy.

[A case of spontaneous pneumothorax due to metastasis of urinary bladder carcinoma to the lung].

We reported a case of spontaneous pneumothorax associated with pulmonary metastasis of urinary bladder carcinoma. A 73-year-old male patient complaining of chest pain and dyspnea was admitted, who had undergone transurethral resection of the urinary bladder carcinoma and diagnosis of inactive pulmonary tuberculosis based on the chest X-ray film finding one year previously. On admission, chest X-ray film showed right pneumothorax, and the re-expanded chest X-ray film revealed a cystic lesion in the right upper lung field adjacent to the anterior chest wall, corresponding to the previous pulmonary lesion. Three months later, right thoracotomy was performed because of relapse accompanying by profuse air-leakage. There was a pleural fistula on the surface of the cystic lesion and necrotic tissue in it. Drainage bronchi were involved by surrounding tumorous tissue. Histological examination of the specimen from the cyst wall disclosed metastasis of transitional cell carcinoma of the bladder. The probable mechanism of the spontaneous pneumothorax probable consisted of stenosis of the right B3 bronchus caused by the metastatic tumor produced a check valve mechanism leading to cystic lesion, the rupture of which caused the spontaneous pneumothorax.

Massive hemoptysis from a pulmonary sequestration controlled by embolization of aberrant pulmonary arteries: case report.

A case of massive hemoptysis due to pulmonary sequestration is presented. Initially, the diagnosis of sequestration was unsuspected and bronchial artery embolization was done for management of hemoptysis from the left lower lobe, but 4 days later massive hemoptysis recurred. Repeat arteriography, including a thoracoabdominal aortogram, revealed two large abdominal arteries penetrating the left diaphragm and feeding the lower lung. Embolization of the aberrant artery from the celiac trunk and the left inferior phrenic artery resulted in complete hemostasis until elective surgical ligation of the two arteries was performed 2 months later. The massive hemoptysis from a pulmonary sequestration could only be controlled after embolization of the transdiaphragmatic aberrant pulmonary arteries.

Skin involvement in Hodgkin's disease: a case report.

Skin involvement of Hodgkin's disease, which typically occurs in the advanced stage, is rare and is associated with a poor prognosis. We report a case of Hodgkin's disease which recurred solely in the skin and followed a favorable clinical course. A 44-year-old Japanese man was diagnosed as having a mediastinal Hodgkin's disease in January 1983. After a complete remission, recurrent skin tumors appeared in the left supraclavicular and anterior chest regions in March 1988. No evidence of lymph nodes or visceral organ involvement was detected. The tumors regressed after chemotherapy. There is no evidence of the disease 7 months after discharge.
