항결핵제 치료 도중 병변이 악화되거나 새로 생기는 경우 일시적인 역설적 반응과 치료 실패를 감별하는 것이 중요하다. 역설적인 반응은 폐외 결핵, 특히 림프절과 중추신경계 결핵에서 잘 나타나는데 기존의 약제를 그대로 사용하더라도 일반적으로 잘 치유가 된다. 저자들은 속립성 폐결절이 항결핵제 투여 후 호전되고 있었으나 두개강내 결절은 오히려 악화된 소견을 보였지만 치료 약제를 변경하지 않았음에도 결국 치유된 역설적 반응을 경험하였기에 이를 보고하는 바이다.

Background: Osteopontin (OPN) and carbonic anhydrase IX (CAIX), which are expressed on the surface of tumor cells, are associated with hypoxia during tumor development and progression. However, the roles of these proteins in the plasma of patients with non-small cell lung cancer (NSCLC) are poorly understood. Herein, we hypothesized that plasma OPN and CAIX levels could be used as diagnostic and prognostic tumor markers in patients with NSCLC. Methods: Fifty-three patients with NSCLC and 50 healthy control subjects were enrolled. We selected controls without malignancy and matched them with NSCLC patient cases according to age and gender. Blood samples were collected at the time of diagnosis; the plasma levels of OPN and CAIX were measured by enzyme-linked immunosorbent assays. Results: The plasma levels of OPN in the patients with NSCLC were significantly elevated as compared to those in the controls (p=0.016). However, there was no difference in the plasma level of CAIX between the NSCLC patients and controls. NSCLC patients with a distant metastasis had a remarkable increase in plasma OPN compared with patients without metastasis (p=0.026), but no such correlation was found for CAIX. There was no difference in overall survival rates according to the plasma level of OPN between the two groups (by Kaplan-Meier survival analysis). Conclusion: Plasma OPN levels were elevated in patients with NSCLC as compared with the controls, with greater elevation of OPN levels in the advanced stages of disease. Therefore, plasma OPN may have utility as a diagnostic, but not prognostic, biomarker of advanced NSCLC.

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.

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.

평소 건강하던 19세 여자 환자가 호흡곤란을 보이며 급속히 진행하는 양상의 폐렴으로 입원, 혈청학적 검사에서 마이코플라스마 폐렴으로 진단되었으며, 초기 스테로이드 투여와 항생제 치료로 증상 호전되어 퇴원하였다. 호흡부전을 동반하면서 광범위한 양측성 폐경변과 흉수 소견을 보이는 중증의 전격성 마이코플라스마 폐렴은 비교적 드물기에 문헌고찰과 함께 바이다.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer related deaths. Most patients were presented with advanced disease at the time of diagnosis. In advanced NSCLC, it is almost impossible to anticipate complete remission by using only cytotoxic chemotherapy or molecularly targeted agents. In our case, two patients were diagnosed as advanced NSCLC and received chemotherapy. They achieved complete response (CR). After finishing treatment, disease recurred. They were retreated with the same regimens and achieved second CR. Until now, they have received each regimen, continuously, and the CR state has been maintained.

Intralobar pulmonary sequestration is a rare congenital lung anomaly. It is defined as a portion of nonfunctioning lung parenchyma that receives its blood supply from an anomalous systemic artery. Patients often present with chronic or recurrent pneumonia. A chest radiograph may show a cystic lesion with air-fluid levels in the lung base. A high index of suspicion is needed for a diagnosis. Surgical removal of a symptomatic intralobar pulmonary sequestration is generally the treatment of choice. Identifying the aberrant artery is a difficult problem when resecting a pulmonary sequestration. The thoracic and abdominal aortas are the most common origins for the abnormal blood supply. However, arterial supply from the celiac artery is quite rare. We present a case of intralobar pulmonary sequestration with the blood supply originating from the celiac artery.

In 2005, a group of mycolic acid-containing bacteria was characterized as belonging to a novel genus, Segniliparus with species Segniliparus rugosus and S. rotundus. We report a case of the S. rugosus isolated from a 54-year-old woman with radiologic features mimicking that of non-tuberculous mycobacteriosis (NTM). When the patient first visited our hospital, an acid-fast bacteria (AFB) smear tested positive and Mycobacterium tuberculosis polymerase chain reaction (TB PCR) was negative in the bronchoalveolar lavage sample. After 2 months, the growing colonies were reported as NTM, but could not be identified because they had died. One year after the initial visit, induced sputum samples showed the same results, positive AFB smear and negative TB PCR. At this point, the growing colonies were identified as S. rugosus. Therefore, we should consider Segniliparus genus as a differential diagnosis for AFB in respiratory specimens in addition to the genus Mycobacterium.

연구배경 : 폐암은 가장 흔한 암중의 하나로 예후가 좋지 않아 폐암의 조기진단은 매우 중요하다. 폐암의 조기진단에는 객담세포진검사와 단순흉부 X-선 촬영이 쓰이고 있으나 이런 방법들에는 한계점들이 있다. 따라서 연구자들은 단순흉부 X-선 촬영상 종괴가 없었던 폐암환자들을 분석함으로써 폐암의 조기진단에 도움을 얻고자 본 연구를 시행하였다. 방법 : 1986년 8월부터 1989년 6월까지 서울대학교병원에서 폐암으로 진단 받은 환자중 단순흉부 X-선 촬영상 종괴가 없었던 11명의 환자들을 대상으로 후향적 연구를 시행하였다. 결과 : 11명중 10명이 남자였고, 8명에서 흡연력이 있었고, 증상으로는 가래, 기침, 그리고 각혈이 많았으며, 이학적 검사상 천명음이나 천음이 들렸던 환자는 3예였다. 단순흉부 X-선 촬영에서 3예에서 확실한 종괴는 없었으나 후에 폐암으로 밝혀진 부위에 불명확한 침윤, 주사열의 비후, 폐결핵증의 소견이 있었으며, 그리고 1예에서는 늑골에 종괴가 가려져 있었던 경우가 있었다. 또 1예에서는 단순흉부 X-선 촬영에서는 종괴가 없었으나 흉부 측면촬영상 종괴가 보였던 경우가 있었다. 폐암의 위치확인의 방법으로는 기관지내시경검사와 흉부 전산화 단층촬영이 유용하였다. 병리학적으로는 11명중 7예가 편평상피세포암이었다. 이들의 병기는 제 2기이하가 5예로서 비교적 조기에 발견된 경우가 많았으며, 11명중 4명이 수술후 2년반에서 4년동안 병의 재발의 증거없이 본원외래를 다니고 있다. 결론 : 호흡기증상이 있고 폐암의 가능성을 배제하지 못하는 환자들에서는 흉부 측면사진과 객담세포진검사 등이 필요할 것이고, 폐암이 의심되면 흉부 전산화 단층촬영과 기관지 내시경 등의 검사들이 적극적으로 시행되어 폐암의 조기진단에 도움을 주어야 한다고 생각된다.

거대세포성 간질성 폐렴은 경금속 도구를 이용한 절삭, 연마공정에서 발생하는 경금속 분진을 흡입하여 발생하는 산업성 폐질환으로 알려져 있다. 저자들은 이러한 특징적인 경금속분진에 대한 노출력이 없이 발생하였던 거대세포성 간질성 폐렴을 수술적 폐생검과 폐조직내 금속 함유량 분석을 통해 진단하였기에 보고 하는 바이다.
