The patient was a thirty years old male, who was diagnosed as having pineal body tumors in June,1969, and treated by irradiation after a ventriculo-atrial shunt operation. He recovered well, and participated in some simple work. In May 1972, he suddenly had convulsions followed by incontinence, and he became nearly apallic. Neuroradiological examinations revealed the presence of left frontal tumor, which was removed, on June 22, 1972. Histological examinations of the tumor proved to be pinealoma of two-cell pattern. Though improved slightly after operation, he became apallic again, developed pneumonia, and died on February 22, 1973.

Out of 1629 patients who were hospitalised 1963 to 1973 for diagnosis and treatment of bronchogenic tumors, 731 underwent resection. 20 patients could be operated upon by lobectomy or bilobectomy and bronchial resection (Sleeve-resection). In two other patients the tumor could be resected through a bronchotomy. Postoperative complications were frequent (n = 6) on patients with malignant tumors (n= 15). We saw 3 times a bronchopleural fistula (2 patients had to be reoperated, 1 death), once a fatal empyema, once a fatal pneumonia of the contralateral side and once a bronchial stenosis of 50% of the lumen. On the patients with a benign tumor (n = 7) we saw in one patient a bronchopleural fistula and in another endobronchialgranulomas due to non resorbable suture material. Methods to prevent or cure these complications are presented consisting in the use of absorbable suture material and long lasting intrathoracic suction.

A case of endobronchial minute leiomyoma successfully treated by bronchoscopically directed forceps biopsy is described. A 42-year-old male with a 20 pack-year smoking history was admitted for dry cough occurring at night. Chest X-ray showed no abnormal shadows. The tumor, measuring 2 by 2 mm, was located in the right B7. The clinical characteristics of the 66 cases of endotracheal and endobronchial leiomyoma reported in Japan are also discussed. The male to female ratio of this disease was 2:3. Middle-aged people were most, commonly affected. Usually, obstructive pneumonia or atelectasis, which develops distal to the lesion, causes respiratory symptoms and chest X-ray abnormality. However, 10% of cases were asymptomatic and 30% had a negative chest X-ray. There were 7 cases of endobronchial minute leiomyoma, measuring less than 10 mm in diameter. Of these, three cases had only hemoptysis and had no chest X-ray abnormality. In such cases fiberoptic bronchoscopy is may be the only useful procedure for the diagnosis of this disease.

Sonographic characteristics of various chest diseases in 154 cases were analysed according to margin of the lesion, internal echogenecity, posterior echo enhancement, air bronchogram etc. We intended to present the basic sonographic patterns of common chest diseases. The study included 10 normal cases, 10 cases with lung abscesses, 31 cases of pneumonia, 24 cases of tumors, 11 cases of obstructive atelectasis, 8 cases of pleuropericarcadial effusions, 10 cases of minimal effusions, 6 cases with pleural thickening, 32 cases of massive pleural effusion with simple compression atelectasis and 12 cases of pneumonia with parapneumonic effusion. Sonographically, normal lung showed hyperechoic zone beneath the chest wall. Identification of arc or ring-shaped wall favored lung abscess. Air bronchogram could only be found in pneumonia. Mass showed various internal echogenecity. The internal echogenecity in obstructive atelectasis was very homogeneous which could not be found in tumor. Pleural thickening showed linear hyperechogenecity beneath the chest wall. In minimal effusion, the line of the diaphragm could be easily identified. Pleuropericardial effusion could be easily diagnosed by chest sonography. The line of the pericarcadium could be clearly identified. The internal echogenecity of massive effusion were various. The internal echogenecity of simple compression atelectasis showed very homogeneous hyperdense internal echogenecity. The internal echogenecity of lung parenchyma in pneumonia with parapneumonic effusion was similar to that of pneumonia. Obstructive atelectasis, mass, consolidation and encapsulated effusion could be differentiated by chest sonography without much difficulty. Sonography could aid chest radiography by giving more morphologic information and was cheaper than computed tomography.

Clinical and paraclinical experience in HIV infection, though the time elapsed since the first observations is relatively short, begins to get typical outlines. In the case of AIDS, the lung is the main place of opportunistic infections, other inflammatory processes and neoplasia. The present work deals with six clinical cases with positive serum tests for HIV and secondary respiratory phenomena such as: Kaposi sarcoma, pneumonia with Pneumocystis carinii, tuberculosis, candidosis, pneumonia with common germs. Particular aspects of treatment and disease evolution are commented.

A case of malignant transformation of benign mixed tumor (pleomorphic adenoma) arising from the right lacrimal gland is reported. A 63-year-old man was referred to our clinic because of visual disturbance and protrusion of the right eye in January, 1989. His past history revealed that he had had a benign mixed tumor of the right lacrimal gland resected 19 years ago. On CT scan, an iso-density lesion homogeneously enhanced with contrast medium was found in the right orbit. This tumor was partially cystic and invaded the cranial cavity. On T1 and T2 weighted MRI, the tumor appeared as an iso-intensity area. At surgery, the tumor was subtotally resected via the combined fronto-orbital approach on February 3, 1990. Histological diagnosis of the tumor was squamous cell carcinoma, and it was construed to be a malignant transformation of mixed tumor of the lacrimal gland. Postoperatively he was placed on a course of external radiation therapy (63 Gy in total) in combination with intra-carotid Cisplatin injection therapy. The first sign of the recurrence was seen as multiple metastatic lesions in both lungs about 4 months after the surgery. In December, 1990, protrusion of the left eye and disturbance of ocular movement became progressively worse. On CT scan, recurrent metastatic tumor was seen in the left orbit and paranasal sinuses. Although additional chemotherapy and irradiation brought about a short period of symptomatic relief he succumbed to pneumonia in April 18, 1990. Metastatic squamous cell carcinoma was confirmed in the lung at autopsy.(ABSTRACT TRUNCATED AT 250 WORDS)

In a prospective study, 14 patients with primary non-oat cell lung carcinoma were treated with intraoperative Iodine125 (I125) implantation of the lung tumor via lateral thoracotomy or median sternotomy. Staging mediastinal node dissection was performed in each case. Patients were selected when wedge or segmental resections were not technically feasible, such that lobectomy or completion pneumonectomy would have been required or pulmonary function studies were poor. Doses ranged from 8,000 cGy at the periphery to 20,000 cGy at the center. With a minimum 12 month follow-up, mean and median survivals were 16.7 and 15.1 months, respectively. Local control was achieved in 10 of 14 patients (71%) with all local failures occurring in pathologic stage III patients. When separated according to tumor size, local control was obtained in six of seven tumors of less than 3 cm and four of five tumors of 3-5 cm. Both cases with masses greater than 5 cm failed locally. There was one operative mortality and two postoperative complications. All other patients were discharged within one week of surgery. There was no radiation pneumonitis. I125 lung brachytherapy is an excellent alternative treatment for T1 and T2 tumors when medical conditions preclude curative resection.

To evaluate utility of Gd-DTPA enhanced MRI (Gd-MRI) in lung cancer, Gd-MRI was performed in 69 cases. 1) Viable tumor was strongly enhanced, necrosis in the tumor, however, was not enhanced on Gd-MRI. Enhanced patterns of Gd-MRI were divided into 3 types, however there was little correlation between the enhancement patterns and histologic types. 2) In serial scan studies of 15 cases, the signal intensity of the tumor reached the peak 3 minutes to 10 minutes after Gd-DTPA administration, and after that the signal intensity decreased gradually. 3) In 23 of 27 (85%) hilar lung cancer cases, Gd-MRI could differentiate the tumor from the peripheral obstructive pneumonia or atelectasis. In 18 of these 23 cases, the peripheral lung disease showed higher intensity than the tumor. 4) In Gd-MRI of pulmonary nodules less than 3 cm in diameter, lung cancers (n = 13) were more strongly enhanced than tuberculomas (n = 5) (p less than 0.001). Based on these data, Gd-MRI was helpful for detecting tumor necrosis and tumor extension on hilar lung cancer with peripheral lung disease. Moreover Gd-MRI may become a feasible diagnostic method for pulmonary nodules.

The cytologic, immunocytochemical, and ultrastructural findings in a 68-year-old man who presented with a malignant pericardial effusion are reported. Radiologic studies failed to identify a primary neoplasm over the next 6 months. Ultrastructural examination of a repeat pericardiocentesis fluid specimen revealed cells with intranuclear tubular inclusions and cytoplasmic lamellar bodies typical of alveolar cell carcinoma. Review of the chest radiographs showed nonresolving patchy infiltrates in the upper lobe of the left lung clinically thought to represent pneumonia; in retrospect, however, these were consistent with the pneumonic form of alveolar cell carcinoma.

Our previous study in patients with small-cell lung cancer indicated that natural alpha interferon might be a radiosensitiser. In this study we considered 20 patients with inoperable non-small cell lung cancer, who were randomly assigned to receive either hyperfractionation radiotherapy alone, 1.25 Gy twice a day (6 hr interval), 60 Gy/48F/32d; or the same radiotherapy concurrently with alpha interferon. Patients in the radiotherapy+alpha interferon arm received 3 x 10(6) IU natural alpha interferon intramuscularly and 1.5 x 10(6) IU inhaled via a dosimeter-equipped jet nebulizer 30 min before each radiotherapy session. Tumor response and radiation-induced lung injury were assessed by serial chest radiographs, computerized tomography scans and lung function studies, during a 1 year follow-up period. No patient in either arm achieved complete response. On the other hand, five patients in the radiotherapy arm and six in the radiotherapy+interferon arm experienced partial response, and the corresponding figures for stable disease were three and one. Combined treatment with radiotherapy and inhaled and intramuscular interferon proved feasible but laborious, for both patients and staff. Pneumonitis and/or oesophagitis in the radiotherapy+interferon arm were moderate to severe, and only two patients tolerated the treatment without any modifications. No treatment modifications were necessary in the radiotherapy arm. The early deaths in the radiotherapy+interferon arm may have been treatment-related. The optimal way to combine interferon and radiotherapy to further evaluate its role as a radiosensitiser needs further studies in larger series.
