[A case of bronchioloalveolar carcinoma diagnosed by a segmental resection].

A 66-year-old man who underwent an extirpation of thymoma in stage I on September 16 1997 was followed in the outpatient clinic. In October 1998, a chest CT scan revealed a 2.0 x 1.0 cm faint frosted glass like shadow in the right S9. On September 13 1999, the patient was admitted to the hospital for close examination. Two times of transbronchial lung biopsy could not offer any clear diagnosis because the lesion was present so as to encircle the central segment of the B9 gronchus. A segmental resection (S9 + 10) under thoracotomy was performed. Intraoperative frozen section diagnosis was bronchioloalveolar carcinoma (type A according to Noguchi's classification), and a resection of the remnant lower lobe and mediastinal lymph nodes dissection (ND 2 a) were added. With expected increase in frequency of detecting early pulmonary cancer's through CT, clinical cases for which we are obliged to diagnosed the disease by segmental resection may increase, if the lesion develops in the vicinity of the hilum of lung like this case.

[Recurrent tuberculous abscess in the chest wall; report of a case].

A case of recurrent tuberculous abscess in the chest wall which was successfully treated by resection of the rib and transposition with a latissimus dorsi muscle flap is reported. A 70-year-old man was admitted to the hospital for the purpose of receiving tuberculostatic treatment after an operation for tuberculous abscess in the chest wall at another hospital. When he first visited the another hospital, he had complained of a left chest wall tumor and Mycobacterium tuberculosis was isolated from the pus. After admission to the hospital, tuberculous abscess recurrenced in the left chest wall 2 months after the operation. We performed resection of the abscess, 5th and 6th ribs, as well as transposition of the latissimus dorsi muscle flap. There have been no signs of recurrence and is followed in the clinic, as of 4 months after the operation. We think that resection of the abscess, ribs, and, transposition of the muscle flap are useful methods for tuberculous abscess in the chest wall.

[A case of schwannoma arising in brachial plexus with intrathoracic extension].

A case of benign schwannoma arising in the brachial plexus with intrathoracic extension was presented. The patient was a 55-year-old man, who was pointed out an abnormal shadow in the left apical region on routine chest X-ray examination. MRI showed that the mass extended to the lowest trunk of the brachial plexus. He had no complaint. Therefore, a diagnostic operation was performed. The tumor was subcapsularly resected with thoracoscopic surgery. Histopathological examination revealed a schwannoma (Antoni type A and B). It should be kept in mind that tumors arising in the brachial plexus are a probable differential diagnosis for tumors at the pulmonary apex, even if no neurological symptoms are seen in the upper extremities.

[Video-assisted thoracoscopical surgery for pericardial cyst: report of two cases].

Two cases of pericardial cyst are reported. Case 1: A 51-year-old man, was admitted to the hospital because of an abnormal shadow on a chest CT scan. We confirmed a cystic mediastinal tumor situated between the superior vena cava and azygos vein. The cystic tumor was excised with a video-assisted thoracoscopic surgical procedure. Histopathological examination revealed a mesothelial-lined structure. Patient 2, a 34-year-old woman was admitted to the hospital because of an abnormal shadow on a chest radiographic film. Chest CT scan showed a cystic mediastinal tumor. The cystic tumor was excised with a video-assisted thoracoscopic surgical procedure. Histopathological examination revealed a mesothelial-lined structure. We would recommend video-assisted thoracoscopic surgery which is of great value in the treatment of pericardial cyst.

[A case report of a mediastinal bronchogenic cyst with back pain].

We performed thoracoscopic surgery for a mediastinal bronchogenic cyst with complaining of back pain. The patient, a 38-year-old male, was admitted with an abnormal shadow on chest X-ray. Chest CT showed a localized tumor on the mediastine. MRI showed a cyst. Under thoracoscopy the tumor was based on parietal pleura and movable in chest cavity. We concluded that back pain was caused by a stimulus of a nerve in parietal pleura. Pathological diagnosis was a bronchogenic cyst.

Bronchial atresia with transient spontaneous disappearance of a mucocele.

We report the transient spontaneous disappearance of a mucocele due to bronchial atresia. Two years before presentation, a chest radiograph showed a hyperlucent right upper lung and a mucocele near the right hilum. A chest radiograph taken 1 year later showed that the mucocele had disappeared leaving an ovoid outline of a dilated bronchus. A chest radiograph obtained 3 months before presentation showed that the mucocele was present again. Atresia of the B3b bronchus of the right upper lobe was noted on thoracotomy. The "disappearance" of the mucocele probably was due to the clearance of mucoid material through collateral airways.

[A resected case under thoracoscopic surgery of bilateral pulmonary metastases of renal cell carcinoma ten years after radical nephrectomy].

A 68-year-old male had received a left nephrectomy for renal cell carcinoma of the clear cell type in October, 1987. He had been given Interferon alpha (IFN alpha) for one year since then. He was referred to our hospital for bilateral abnormal shadows on the chest roentgenogram in December, 1997. He underwent a video-assisted thoracoscopic biopsy of bilateral lung in January, 1998, 11 years after his nephrectomy. The resected specimens contained a coin lesions measuring approximately 2 cm in diameter, and the lesions were microscopically diagnosed as a renal cell carcinoma of the clear cell type metastatic to the lung. The patient is doing well with no signs of re-recurrence five months after the resection of the metastatic lesion.

[An effective case of a new biological adhesive agent, gelatin-resorcinol formaldehyde-glutaralhyde glue (GRFG-glue) in treating refractory pulmonary fistula following lobectomy for pulmonary aspergilloma].

We report a successful case of thoracoscopic therapy using a new biological adhesive agent, Gelatin-Resorcinol Formaldehyde glue (GRFG glue) for refractory pulmonary fistula. A 69-year-old male underwent right upper lobectomy for lung aspergilloma. Air leakage began 11 days after lobectomy. Closing alveolar fistula was performed 28 days after first operation. Relapsing air leakage began 2 days after second operation. The insertion of fibrin glue through thoracoscope at two times was not effective for refractory pulmonary fistula. But the insertion of GRFG glue was effective to close the fistula completely.

Microbial flora of the normal esophagus.

The endogenous flora of the skin and some mucous membranes are well known, however, we were unable to find descriptions about normal esophageal flora in literature. We believe that knowledge about normal esophageal flora is important for therapeutic implications. We compiled data on 30 patients without infection of the oropharynx or esophagus who were admitted for an endoscopy of the upper digestive tract to determine normal esophageal flora. The samples were collected by injecting 10 ml of 0.9% physiological solution into the esophagus and oropharynx and removing it by suction. Esophageal samples from 30 patients and oropharingeal samples from 10 of these patients were collected. We identified mixed flora being Streptococcus viridans the most frequent microorganism found. Where samples from both the esophagus and oropharynx were collected, three occurrences of this same microorganism were found. We concluded that the isolation frequency of germs in the esophagus by the method used was high and the most frequently found germ was S. viridans. There is therefore a possible correlation between the flora from the oropharynx and the esophagus.

[Three resected cases of pulmonary cryptococcosis].

Case 1 was a 53-year-old female who had a small nodule in the right S3 segment on chest CT. As she was not diagnosed by transbronchial lung biopsy (TBLB), open thoracotomy was performed. Case 2 was a 65-year-old female who had a nodule with pleural indentation in the right S6 segment. As this nodule showed difficulty to differentiate from small lung carcinoma, thoracoscopic surgery was performed. Case 3 was a 63-year-old female who had multiple lesions with cavity in the left S4 and S5 segments, which was preoperatively diagnosed by TBLB. She was performed thoracoscopic partial resection of the lingular segment because of poor response to antimycotic agents. All cases received preventive antimycotic agents for one or two months after the operation. There was no recurrence or postoperative meningitis. Thoracoscopic surgery is the effective procedure for the diagnosis and treatment of the localized pulmonary cryptococcosis.

[A resected case of a bronchiolo-alveolar cell carcinoma of the lung accompanying pneumonia-like shadow on chest roentgenogram].

A 67-year-old female was admitted to our hospital because of pneumonia-like shadow on chest roentgenogram with persistent cough and sputum of 4 months duration. Diagnosis as lung cancer was delayed more than 4 months. She showed fever and inflammatory reactions. Antibiotics were effective to inflammatory reactions, but not effective to pneumonia-like shadow. Transbronchial lung biopsy was useful for the diagnosis. Right lower lobectomy was performed. In this case, tumor extents were limited within one lobe. Tumor cells did not invade blood and lymphatic vessels, and extrathoracic metastases were not detected. The prognosis of bronchiolo-alveolar cell carcinoma was determined by intra-pulmonary tumor extent. Based on a comparison with the outcome of unresected cases, bronchiolo-alveolar cell carcinoma limited within one lobe should be surgically resected.

[A case of intrathoracic lipoma arising from the chest wall resected by video-assisted thoracoscopic surgery].

We present a case of lipoma arising from the chest wall spreading into the thoracic cavity. Although asymptomatic, a 65-year-old female was pointed out an abnormal shadow on the chest X-ray film taken at the mass survey. The tumor, measuring 3.4 x 3.0 x 2.0 cm in diameter, was surgically removed under thoracoscopic visualization through a small thoracotomy incision of lt. 1st intercostal space, and the diagnosis of lipoma was confirmed postoperatively by histopathologic examination.

[Study on cases of resected primary lung cancer in young persons].

A clinical study was conducted of 17 patients aged less than 40 years who received resection for lung cancer in our department. The 17 cases made up 1.8% of the total series of 924 resected lung cancer cases, with the number of cases increasing as the age of 40 years was approached. The male-female ratio was 1.1:1, with proportion of women higher than in the total series of lung cancer cases. The histological type of included a high proportion of adenocarcinomas (47.0%), while squamous cell carcinomas were few. In addition, the proportion of tumors of low-grade malignancy such as carcinoid tumors and mucoepidermoid carcinomas was high. The majority (58.8%) of cases were detected by mass screening. As a result, the number of stage I cases was high (10 cases, 58.8%), and curative resection could be performed in 70.8%. The prognosis of these young patients did not differ significantly from that of the total resected group, with a 5-year survival rate of 62.4% achieved. It was considered that the prognosis of lung cancer in young persons can also be improved with early detection by mass screening and active surgical intervention.

Claws of cilia: further observation of ciliated epithelium in neurenteric cyst.

Claw-like projections and related structures on cilium tips in neurenteric cyst epithelium are described. The ciliary claws are about 20 nm in length and just beneath them four parallel electron-dense areas or lines are discernible. Similar structures were also observed in another case of neurenteric cyst. These structures are very similar to those reported previously, and it is suggested that they are commonly present in various ciliated epithelia in Man.

Fine surface structure of an intraspinal neurenteric cyst: a scanning and transmission electron microscopy study.

The case of an 11-year-old boy with an intraspinal neurenteric cyst, which recurred 8 years and 3 months after surgery, is presented. Scanning and transmission electron microscopy of the cyst epithelium revealed marked resemblance to that of the respiratory tract, despite the presence of numerous goblet cells mimicking intestine on light microscopy study. Detailed ultrastructural findings are described.
