The specific diagnosis in diffuse interstitial lung disease may be obtained through open lung biopsy. Diffuse interstitial lung disease is often associated with lung cancer. We report one case of lung adenocarcinoma with idiopathic pulmonary fibrosis in whom previous open lung biopsy had been performed. We need general concepts about sites of open lung biopsy in these patients. Therefore, we report this case and document other references.

Minimizing patient movement during CT-guided lung biopsy is an important factor in the procedure. To minimize movement, a vacuum cushion was used to evaluate its effectiveness. The subjects of this study were 116 patients aged 40 years or older who had good coordination with postural fixation and breathing control. Posture measurements were performed in the supine position, prone position, oblique position, and lateral position according to each position of the lung lesion biopsy lesion. Measurement positions were measured in the anterior, posterior, right, and left positions based on the anatomical posture. In the prone position, the mean difference between the non-use and the use of the posterior was 1.7905, and t=2.913 (p<0.01), and the mean difference between the non-use/use was statistically significant. The difference between the unused and used averages of left was 2.4105, and the difference between the left averages was also significant with t=3.684 (p<0.01). The difference between the unused and used averages of the right was 2.3263, with t=3.791 (p<0.01). The mean difference between unused and used is statistically significant. As a result of statistical analysis, the biopsy of the lung lesion using a fixation device showed less movement in all postures. It is considered that it is meaningful in that it is possible to conduct a more accurate biopsy procedure and minimize the patient's posture movement by using a fixation device during the CT-guided biopsy of the lung lesion.

Percutaneous transthoracic needle biopsy (PTNB) is a minimally-invasive procedure that is an indispensable tool for evaluating pulmonary lesions. Though extremely rare, tumor seeding of the pleura and chest wall can occur as a complication. Given that the breast is located anterior to the thorax, needle tracking through the breast is inevitable when PTNB is performed using the anterior approach. We describe tumor seeding of metastatic pulmonary ameloblastoma in the pectoralis muscle layer of the breast along the needle track of PTNB in a 51-year-old female presenting with a palpable lump in the right breast.

Epithelioid hemangioendothelioma, originating from the vascular endothelium, is a very rare and low-grade malignancy. World-wide, about 50 cases of pulmonary epithelioid hemangioendothelioma have been reported. This is more common in female and is usually shown as multiple nodules in both lung fields. A 41-year-old male, who had suffered from right pleuritic chest pain for 3 months, was initially diagnosed as adenocarcinoma under bronchofiberscopic biopsy. At that time, the stage of tumor according to the TNM staging was llla. He received bronchoscopic biopsy again during follow-up period and it was diagnosed as hamartoma. After surgery, the final diagnosis was pulmonary epithelioid hemangioendothelioma.

We described herein the first case of primary $Sj{\ddot{o}}gren^{\prime}s$ syndrome in Korea which presented with multiple cysts caused by only peribronchiolar lymphocytic infiltration, a rare pulmonary manifestation in $Sj{\ddot{o}}gren^{\prime}s$ syndrome, and was confirmed by surgical lung biopsy. A brief review of the literature has been included.

Background and Methods: To study the effects of corticosteroid (CS) on the parquat (PQ) induced lung injury, serial cellular analyses of bronchoalveolar lavage (BAL) fluid were done with simultaneous histopathologic examination after intraperitoneal injection of PQ on the rats. The sacrificed animals were divided into three groups; control group, PQ group received intraperitoneal injection of 20 mg/kg of PQ, and CS group received daily injection of Methylprednisolone sodium succinate (20 mg/kg) in addition to PQ. Results: 1) Cellular analyses of BAL fluid: The total cell count in the BAL fluid were increased gradually from 6 hours after PQ administration (p<0.05), and was decreased at 3 days after (p<0.05). These changes were mainly due to the effects of PQ on the neutrophil influx (p<0.05). But, the number of macrophage and the percentage of lymphocyte in total cells showed little changes. The CS administration showed the suppression of neutrophil influx in the BAL fluid (p<0.05), but could not show any significant effect on the number of macrophage and lymphocyte. 2) Histopathologic examination: In the PQ group, inflammatory changes especially with prominant neutrophil infiltration were gradually progressed over time. Those changes were found in both alveolar space and interstitium with resultant alveolar structural changes, but subsided from 3 days after. CS suppressed inflammatory changes in the alvolar space and interstitium, especially with decreased infiltration of neutrophil. Conclusion: CS suppressed neutrophil infiltration in the acute lung injury induced by PQ, those findings were ascertained by serial cellular analyses of BAL fluid and histopathologic examination.

Background: Transbronchial lung biopsy(TBLB) has known to yield useful information for pulmonary infiltrates of uncertain etiology, However, its safety and usefulness have not been conclusive in the critically ill patients with respiratory failure. Moreover, TBLB has not been recommended for patients with mechanical ventilation. This study was conducted to investigate the diagnostic values and risks of Will performed on critically ill patients at bedside to obtain information on the pulmonary infiltrate of unknown etiology. Methods: Twenty patients(21 admissions with 23 cases) with diffuse pulmonary infiltrates who were treated in a medical intensive care unit of a tertiary referral hospital from January 1994 to May 1998, were enrolled for the study. Their medical records were retrospectively reviewed. TBLB was opted when a noninvasive diagnostic work-up failed to reveal the cause for the pulmonary infiltrate. The procedure was performed at patients' bedside without assistance of fluoroscopy. Bronchial washing or bronchoalveolar lavage was performed on the same pulmonary segment before performing TBLB. Results: Adequate specimens were obtained in 18 cases(78%). TBLB provided a specific diagnosis in two cases. The results of TBLB suggested the underlying etiology in 9 cases; bacterial pneumonitis(4), hypersensitivity pneumonitis(1), polymyositis(1), radiation fibrosis(1), idiopathic pulmonary fibrosis(1), and BOOP(1). Therapeutic decisions were altered in 11 cases(47.8%) based on the TBLB results. Pneumocystis carinii was found in the BAL fluid of another case. Ten patients with a therapeutic change and ten patients without a management change had mortality rates of 40% and 80%, respectively. The APACHE III scores were significantly higher in patients with complications($72.8{\pm}21.8$) compared with those without complications ($48.3{\pm}18.9$)(p<0.05). The complication rates were higher in those with mechanical ventilation(50%) than in those without Mechanical ventilation(33%), but the difference was not statistically significant(p=0.3). Conclusions: TBLB may be a useful diagnostic option for critically ill patients with unknown cause of pulmonary infiltrates. However, it should be cautious be used with care for patients with mechanical ventilation or for severely ill patients.
