Neurilemmoma is a benign nerve sheath tumor derived from Schwann cells and occurs in the head, neck, flexor regions of the extremities, posterior mediastinum but extremely rare in the chest wall. They occur at all ages but are most common in persons between the ages of 20 and 50 years and develop spontaneously or possible as a result of trauma or irritation. The diagnosis of a neurilemmoma is confirmed histologically by the findings of Verocay bodies, Antoni A and B tissue patterns and the presence of S-100 protein. We experienced a case of chest wall neurilemmoma which was treated by local excision and report it with a brief review of the literature.

A-59-year old man was admitted to the hospital with a 2-month history of the right pleuritic chest discomfort and mild dyspnea. Seven years earlier, he was operated on left pneumonectomy for squamous cell carcinoma of left upper lobe (Stage IIb, $T_2N_1M_0$). The computed tomographic scan revealed an anterior herniation of the right lung in the left hemithorax. A single thorax after receiving pneumonectomy is called a "buffalo chest" because the absence of an anatomical separation of the two hemithoraxes resembles that of the North American buffalo or bison. A possible pneumothorax should be catastrophic for the patient, so he should be closely monitored regarding any invasive procedure or trauma. He improved after symptomatic treatment.

Background : We have studied the $^{67}Ga$ SPECT to determine the activity of pulmonary tuberculosis, especially in patients with minimal extent of the disease on chest radiographs. Because active minimal pulmonary tuberculosis is sometimes difficult to diagnose by means of initial chest X-ray, sputum examination and $^{67}Ga$ planar imaging, we compared $^{67}Ga$ planar imaging with SPECT to evaluate minimal pulmonary tuberculosis activity. Methods : $^{67}Ga$ planar imagings and SPECTs of 69 patients suspected of minimal pulmonary tuberculosis by the initial chest X-ray were performed and compared to each other. Active pulmonary tuberculosis was defined by a positive AFB smear and/or culture in the sputum and changes shown on the serial chest X-ray findings. Results : 1) $^{67}Ga$ planar imaging imagings showed positive uptakes in 24 patients and no uptakes in 13 patients, patients, which confirms active pulmonary tuberculosis. But SPECT imagings showed positive uptakes in 25 patients and no uptakes in 12 patients. 2) Patients confirmed with inactive pulmonary tuberculosis showed no uptake on $^{67}Ga$ planar imaging. Only one of the 32 patients confirmed as having inactive pulmonary tuberculosis showed positive uptake on $^{67}Ga$ SPECT imaging. Conclusions : According to the results of our study, $^{67}Ga$ planar imaging and SPECT are both sensitive in detecting the activity of minimal pulmonary tuberculosis. The difference between the two methods is not statistically significant, and the negative predictive value of the $^{67}Ga$ SPECT is not higher than that of $^{67}Ga$ planar imaging.

We have experienced 131 cases of chest wall tumor, from April 1974 to April 1984 at the Kyung Hee University hospital. We analyzed 131 cases of chest wall tumors, 59 cases were primary chest wall tumors and 72 cases were secondary chest wall tumors. The results were following; 1.Of primary benign chest wall tumors [56], lipomas were most common and located mainly in the scapular area [37/56]. 2.Of secondary malignant chest wall tumors [72], which originated from hung tumors were most common [27/72], & breast [8/72], liver [8/72], prostate [6/72] & stomach [3/72] were followed lowed in orders. 3.We excluded out the Rib tuberculosis.

Mucoepidermoid carcinoma of lung are rare carcinoma arising from the submucosal glands tissue of the proximal tracheobronchial tree. The carcinoma can be divided into low grade and high grade varienties. The most important factors in the prognosis include histological grading and the ability to achieve a complete surgical resection. We experienced a case of high grade mucoepidermoid carcinoma in pulmonary tuberculosis patient of 67 years old male who has been suffered from left chest pain for several weeks. He was not treated and died seventeen months later.

Background: We investigated the prevalence of latent tuberculosis infection (LTBI) among medical students in South Korea. Methods: Students from one medical school, who were in second- or third-year classes before clerkship course, were enrolled for three consecutive years in the study. A standard questionnaire was given to each participant, and tuberculin skin test (TST), QuantiFERON-TB GOLD In-Tube (QFT-GIT) assay, and chest radiography were performed. Results: A total of 153 participants were enrolled in the study. The mean age of the subjects was $21.9{\pm}0.9$ years, 105 (68.6%) were male, and 132 (86.3%) had been vaccinated with Bacille Calmette-Gu$\acute{e}$rin (BCG). Four students (2.6%) had a history of contact with tuberculosis (TB) patients during medical practice. No abnormal chest radiograph findings were found for any of the subjects. Of the 153 subjects, 23 (15.0%) tested positive for the TST, and 8 (5.2%) tested positive for the QFT-GIT. The agreement between the two tests was determined to be 0.34 using kappa coefficients. Of the four students who had a history of contact with TB patients, only one subject tested positive for both tests, and the other three students tested negative for both tests. Conclusion: A low prevalence of LTBI was found among medical students before clerkship course in South Korea.

Bilateral interstitial infiltration in chest radiography, which may be fine granular, reticular or of ground glass opacity, is the typical radiographic findings of Pneumocystis jiroveci pneumonia. Recently, atypical radiographic features, including cystic lung disease, spontaneous pneumothorax or nodular opacity, have been reported intermittently in patients with P. jiroveci pneumonia. We report the case of a 29-year-old woman with a transplanted kidney whose simple chest radiography and HRCT scan showed numerous miliary nodules in both lungs, mimicking miliary tuberculosis (TB). Under the presumptive diagnosis of miliary TB, empirical anti-TB medication was started. However, Grocott methenamine silver nitrate staining of a transbronchial lung biopsy tissue revealed P. jiroveci infection without evidence of TB. These findings suggest that even in TB-endemic area other etiology such as P. jiroveci as well as M. tuberculosis should be considered as an etiology of miliary lung nodules in mmunocompromised patients.

The author reviewed 36 cases of misdiagnosis in 533 cases of Surgical chest diseases which were operated during past 5 years in Department of Thoracic Surgery in Busan University Hospital. The detail of cases are as follows; 11 of 162 cases in pulmonary tuberculosis, 5 of 133 cases in empyema, 3 of 29 cases of mediastinal tumor and 7 of 155 cases of miscellaneous. rate of misdiagnosis in all cases was 6.5%. The author further discussed the factor of misdiagnosis in these cases and some diseases which were needed differential diagnosis.

Diffuse panbronchiollitis (DPB), a rare progressive disorder, has lately been receiving increasing attention. DPB is a disease of obscure etiology, characterized by chronic inflammation localized mainly in the region of respiratory bronchiole just distal to the terminal bronchioles. In 1983, Homma and coworkers reported 82 cases of a new clinicopathological entity, DPB, in Japan. Also DPB is a disease largely restricted geographically to Japan but the prevalence in other countries is extremely low. Histoloically, it is characterized by a suppurative bronchiolitis involving primarily the respiratory and terminal bronchioles with subsequent progression to bronchiectasis. The disease progresses rapidly and results in respiratory failure due to repeated respiratory infections. We experienced a cases of DPB accompanied with chronic maxillary sinusitis in both sinuses. Diagnosis of DPB was comfirmed by pathological results from thoracoscopic lung biopsy, typical radiological findings, clinical symptoms and pulmonary function test. After treatment with erythromycin for 6 months, the patient's condition and the typical micronodular densities on the chest radiography improved. A few case of DPB was reported in Korea. We report a case of DPB through thoracoscopic lung biopsy.
