Since Ikeda in traduced flexible fiberoptic bronchoscope in 1968, use of bronchoscopy was expanded rapidly. Wide use of flexible bronchoscopy enabled us to get tissue diagnosis with more ease and safety. Authors analyzed 71 cases of tissue biopsy of 233 bronchoscopies from June '76 to. Jan. '78 and concluded as following : 1. 233 bronchoscopies af 20 Month duration, cases which needed tissue biopsy were 71 cases (30.5%). 2. Chief complaints af above cases are coughing, dyspnea, sputum, chest pain, hemoptysis in frequency. 3. Biopsy sites were as following in frequency: Rt.upper lobe, Lt. main bronchus, Lt. upper lobe, Rt. main bronchus, Lt. lower lobe. 4. The final diagnosis of biopsied cases were cancer 80%, tuberculosis 15%, and malignant mesothelioma, anthracosis, aspergillosis, were one case each. 5. Among 57 case of lung cancer, biopsy confirmed cases were 36 cases (63%). 6. Pathologic finding of 36 case of Biopsy confirmed lung cancer was as following: Squamous cell ca : 64% Anaplastic ca : 25% Adeno ca : 2.8% Unclassified: 2.8% 7. Bronchographies were done in 36cases (51%), one quarter of cases before biopsy, and three quarters of cases after biopsy. 8. Cytology was requested in 76% of cases with following results; PAP class V 15%, class IV 7.5%, class III 1.8%.

Background : We assessed the accuracy of staging in evaluation of bronchial invasion, thus found the role of CT in patients who underwent resective surgery in primary lung cancer. Materials and Methods : Authors retrospectively analized the preoperative CT scans of 156 patients receiving pneumonectomy(n = 95) and lobectomy(n = 61). Among lobectomy patients, 7 patients subsequently performed pneumonectomy because of positive resection margin of bronchus in frozen biopsy. We also retrospectively analized CT scans of non-operated 60 patients who performed sufficient bronchoscopic biopsy. Bronchial wall thickness more than 3mm, irregular wall thickening and reduction of diameter by CT were defined as bronchial invasion. The pathologic examination of resection margin were positive in 20, stump recurrence occurred in 6 of the operated group, and the pathologic examination of biopsy of bronchial wall were positive in 34 of the non operated group, and these were an regarded as bronchial invasion. Results : The CT assessment of bronchial invasion revealed low sensitivity (11.5%), low positive predictability(38%), but high specificity(96%) and relatively high accuracy (84%) in the operated group and higher sensitivity (62%), higher positive predictability(95%) in non-operated group. Conclusion : In lung cancer patients who underwent operation, CT showed very low sensitivity and positive predictability in evaluation of bronchial invasion. Because the usefulness of CT in evaluation of bronchial invasion is limited, therefore aggressive fiberoptic bronchoscopic biopsy is thought to be necessary before surgical attempt.

A primary pulmonary malignant lymphoma is a rare disease. It is thought to be a category of non-Hodgkin's lymphoma arising from the bronchous-associated lymphoid tissue (BALT). The majority of primary pulmonary lymphomas are low-grade, small B-cell lymphomas, which are associated with Sjogren's syndrome and similar autoimmune disorders. A case of primary pulmonary low-grade B-cell lymphoma arising from the BALT was encountered in a patient with systemic lupus erythematosus. A 54-year-old man was admitted to the hospital for the evaluation of left pleuritic chest pain and multiple joint pain in both hands. Serologic tests for collagen vascular disease were performed. The results of ANA and anti-ds-DNA were all positive. The computed tomography of the chest showed patchy consolidations in the left lower lobe with a pleural effusion and a video-assisted thoracoscopic biopsy was performed. Here we report a case of a low-grade B-cell lymphoma of BALT in a patient with systemic lupus erythematosus with a review of the relevant literatures.

Primary pulmonary lymphoma (PPL) is an uncommon tumor, which constitutes 3-4% of all extranodal lymphomas and 0.3-0.5 % of all primary pulmonary malignant tumors. Low-grade B-cell lymphomas of bronchus-associated lymphoid tissue (BALT) accounted for the majority of PPL. This BALT lymphomas are frequently asymptomatic and have an excellent prognosis and an indolent clinical course by contrast with T-cell type. Therefore, determination of the B- or T-immunophenotype of the tumor cells is known to be very important from a clinical aspect. Recent advances in immunohistochemical techniques, cytogenetics, and molecular biology have allowed better definition of type, maturation, and clonality of lymphoma cells and have made it possible to better understand the PPL. We experienced an asymptomatic 43-year-old man who was evaluated for infiltrates on both sides discovered incidentallly after a routine chest roentgenogram. He was eventually diagnosed as low-grade B-cell lymphoma of BALT by immunohistochemical staining from specimens obtained by open lung biopsy. He was treated with combination chemotherapy. At follow up 12 mons following initial diagnosis, he remains in stable. We report this case, who showed a relatively favorable prognosis and indolent clinical course compatible with low-grade B-cell lymphoma.

We have analysed the 76 cases of the foreign bodies of our ENT department during the period from Jun. 1973 to Feb. 1983. The following results were obtained and were reported. 1) Distribution of these whole 105 cases, 68 cases (64.8 %) were lodged in esophagus, 13 cases (12.4 %) were in the nasal cavities, 9 cases (8.5 %) were in the oral cavity and throat, 8 cases (7.6 %) were in the air passages, and 7 cases (6.7 %) were in the external auditory canal. 2) The sorts of the esophageal foreign bodies, the coins were the most cases(53 cases - 77.9 %) and other sites were shown of variable kinds. 3) Age distribution of the esophageal foreign bodies were mostly in under 5 years of age (49 cases - 72 %) and in cases of the air passages, all the 8 cases were in under 10. 4) In the localities of the esophageal foreign bodies, first narrowing was the most frequent site (61 cases - 89.7 %), and of air passages, 6 cases were in the left main bronchus, more that of Rt. main bronchus. 5) During the lodgement of esophageal foreign bodies, 58 cases (85.3 %) were visited to our ENT department within 24 hours. In the cases of air passages, most were viaited in 3 to 7 days (6 cases -75 %).

The statistical study was done on 74 cases of foreign bodies in the air passages, who visited the department of otolaryngology of SNUH during recent 5 years from 1975 to 1980. The result was as follows, 1) Of the total 74 cases, 55 cases were male and 18 cases were female. The ratio between male and female was 3 : 1. 41.8% of all-cases were under 2 years of age, 75.5% were under 3 years, and 83.6% were under 5 years. 2) Major symptoms on visit were dyspnea, cough, cyanosis. No significant symptoms was noted in 6.7%. Initial physical findings were coarse breathing sound, decreased breathing sound, and stridor. No abnormal physical findings were noted in 10.8%. 3) 48.6% of total cases visited hospital within 24 hours. There was one case who visited hospital over 2 years later. 4) Initial simple chest film showed atelectasis in 25.0%, emphysema in 32.8%, definite foreign body shadow in 17.2% and within normal limit in 17.2%. 5) 60.8% of total cases were vegetables, 15.5% were metals, 16.2% were fish bone, and 2.7 % were others. 6) Vegetables were most frequent foreign bodies in the cases under 5 years of age. 7) 40.5% of total cases were lodged in the right main bronchus, 31.0% were in the left main bronchus, 9.8% were in trachea and 6.7% were in multiple sites, 8) Foreign bodies were removed by ventilating bronchoscopy in 82.3%, by tracheostomy only in 2.7%, by tracheal suction in 2.7%, by spontaneous removal in 1.3%, by thorachotomy in 5.4% and 5.4% of total cases were expired.

A 62-year-old man with a chronic cough presented with atelectasis of the left upper lobe on chest X-ray. Chest computed tomography showed an atelectasis in the left upper lobe with bronchial wall thickening, stenosis, dilatation, and mucoid impaction. We performed bronchoscopy and found a well-circumscribed mass on the left upper lobe bronchus. The mass was removed by flexible bronchoscopy using an electrosurgical snare and diagnosed with lipoma. An endobronchial lipoma is a rare benign tumor that can be treated by a surgical or endoscopic approach. We report the successful removal of endobronchial lipoma via flexible bronchoscopic electrosurgical snare.

Background: Cancer is a major health problem facing the entire world, and Jordan is no exception. However, patterns of cancer incidence and cancer burden in Jordan have never been explored thoroughly, and the aim of this study was to close this knowldege gap. Materials and Methods: The study was based on data obtained from the Jordan cancer registry from 1996 to 2009. All cancer cases that were diagnosed during the study period were registered and included in this study. Results: A total of 51,626 cases were registered in Jordan during the 14- year period. The incidence rate showed no significant increase in males (percent change PC 6.8%), while in females a marked increase was observed (PC 14.8%). The major cancer sites for males were bronchus and lung, colorectal, bladder, leukemia and prostate. In females, the leading cancer sites were breast, colorectal, leukemia, thyroid and NHL. Conclusions: Compared to other countries in the region, Jordan has comparable rates. On the other hand the rates of cancer are markedly lower in Jordan compared to more industrialized countries such as the US and Europe. There was an overall increase in the incidence of cancer in Jordan, especially among females, which stresses the need for programs to raise awareness on the importance of early diagnosis and preventive life style measures.

Background: Cancer incidence data are vital for cancer control planning in any nation. This retrospective study was conducted to compare the cancer incidence of all sites between the first cancer registry report and the most recent example in Nepal. Material and Methods: The cases in the first (2003) and latest (2013) national cancer registry reports, accumulated by all the hospital based cancer registries in Nepal were taken for the research. The frequencies, crude incidences and age specific incidences (per 100,000) of the five major cancers were calculated for both males and females. Result: The most common cancer type for males in both years 2003 and 2013 was lung. Stomach was the third most common cancer in 2003 while it was the second in 2013. Similarly, the first four major cancers (cervix, breast, lung and ovary) did not change between 2003 and 2013 in females. The total cancer incidence rate increased from 12.8 in 2003 to 30.4 per 100,000 in 2013 for males and from 15.1 to 33.3 in females. Conclusion: The most common cancers in males in 2003 and 2013 were the bronchus and lung. Similarly, the most common cancer in females was cervix at both time points. The cancer incidence rate in females was higher than in males both in 2003 and 2013.

Bronchial webs are rare lesions which often go unrecognized. A 36-year-old female was admitted to our hospital for recurrent cough and dyspnea. A diagnosis of bronchial asthma was made and she was treated with conventional therapy. She did not respond to drug therapy. On the physical examination, there was localized wheezing on the left lung field. By the bronchogram, we found a membrane-like structure in the left main bronchus. A bronchoplasty was performed and now the patient leads her normal life without any medications for asthma.
