연구배경 : 피부근염/다발성근염 환자의 폐침범에 대한 국내의 보고는 드물며, 이에 폐를 침범한 피부근염/다발성근염 환자의 임상상을 살펴보았다. 방 법 : 1989년부터 1999년까지 서울대병원을 내원한 피부근염/다발생근염 환자의 임상양상과 방사선검사를 포함한 검사소견을 후향적으로 분석하였다. 결 과 : 총 79명(피부근염/다발성근염 : 54/25명)의 환자 중 24명(33%)의 환자에서 폐침범이 있었다. 폐침범이 있는 환자군의 여성비(11:1)와 연령($50{\pm}13$세)이 높았다. 폐침범이 있는 환자에서 호흡곤란(79%)과 기침(67%)의 증상이 있었고, ESR이 $47{\pm}7\;mm/hr$, CK/LD가 $2169{\pm}820/577{\pm}61\;IU/L$로 증가하였다. Anti-Jo1 Ab는 30%에서 양성이었다(p-value : 0.03). 흉부 HRCT 상 망상 또는 간유리 음영(9%), 선상 음영 또는 중격 비후(50%), 반점상 경화(38%), 벌집낭(33%), 결절 음영(17%)으로 관찰되었다. 환자는 $30{\pm}28$개월 동안 추적관찰 되었고, 스테로이드 단독치료(46%)와 면역억제제 병행치료(50%)를 받았다. 경과 중 사망률은 폐침범이 있는 군(21%)에서 폐침범이 없는 군(10%)보다 높은 경향을 보였다.

Atypical adenomatous hyperplasia (AAH) has been considered to be a precursor lesion of bronchioloalveolar carcinoma (BAC) and pulmonary adenocarcinoma. It usually coexists with BAC and/or an adenocarcinoma. Chest computed tomography reveals multiple well-defined nodules with ground-glass opacity. Usually, AAH does not exceed 10 mm in size. AAH with extensive involvement on one side of the lung field or one that is larger than 2 cm has not been previously reported. We herein report a case of a 71-year-old nonsmoking female with lung AAH of larger than 2 cm.

Background: Recent studies revealed a relationship between ground-glass opacity (GGO) ratio on computed tomography (CT) and serum carcinoembryonic antigen (CEA) level in lung adenocarcinoma. Since an association between lepidic histologic pattern and GGO is well accepted, we investigated the link between histologic subtype and serum CEA level in resected lung adenocarcinoma. Materials and Methods: One hundred and eighty-one consecutive patients with resected lung adenocarcinoma were studied retrospectively. The histologic subtype was subdivided into 2 groups: lepidic dominant histologic subtype, including adenocarcinoma in situ, minimally invasive adenocarcinoma and lepidic predominant invasive adenocarcinoma versus other subtypes. Results: The 5-year survival of patients with s high serum CEA level was significantly more unfavorable than that with normal levels. Similarly, there was also a relationship between the patient survival and histologic subtype, with favorable survival found in patients with the lepidic dominant histologic subtype. There was a significant relationship between serum CEA level and lepidic dominant histologic subtype overall and in p-stage I patients. Conclusions: Lung adenocarcinomas with non-lepidic dominant histologic subtype are associated with high serum CEA levels.

Varicella is a contagious infection in childhood disease typically affecting children aged 2-8 years and usually follows benign outcome. In the adult, clinical presentation is more severe and more commonly associated with complications. Varicella pneumonia, although rare, is a potentially life-threatening complication that should be suspected in any adult with varicella and respiratory symptoms. We report a case of varicella pneumonia in immunocompetent patient. The characteristic radiographic findings consisted of diffuse scattered coarse nodular infiltrations, less than 1cm sized, with ground glass opacity and consolidation in both lung fields. The patients was started on intravenous acyclovir. The chest radiograph performed 2 weeks later showed complete resolution of the pulmonary lesions.

A 45-year-old man presented with dyspnea and hemoptysis during exercise. A chest computed tomography (CT) revealed multifocal diffuse patchy ground glass opacity and interlobular septal thickening in both the lungs. Permeability pulmonary edema or pulmonary hemorrhage was suspected. Serologic studies for autoimmune disorders and vasculitis were negative. There was no laboratory evidence of coagulopathy, other hematopoietic disease or infectious disease. Considering correlation with exercise, we diagnosed exercise-induced pulmonary hemorrhage (EIPH) or exercise-induced pulmonary edema (EIPE). The patient was managed with antifibrinolytics, antibiotics, and antitussive agent. After a week, follow-up chest CT revealed completely resolved pulmonary hemorrhage. About 2 months after the first event, he visited again with dyspnea and hemoptysis during running. In the present study, we report a case of recurrent pulmonary hemorrhage after exercise.

Rhinovirus infection is typically associated with the common cold and has rarely been reported as a cause of severe pneumonia in immunocompetent adults. A 55-year-old previous healthy woman, who consumed half a bottle of alcohol daily, presented with respiratory failure after one week of upper respiratory infection symptoms. Radiography revealed bilateral, diffuse ground glass opacity with patchy consolidation in the whole lung field; bronchoalveolar lavage fluid analysis indicated that rhinovirus was the causative organism. After five days of conservative support, the symptoms and radiographic findings began to improve. We report this rare case of rhinovirus pneumonia in an otherwise healthy host along with a review of references.

Background: Micro computed tomography (CT) is rapidly developing as an imaging tool, especially for mice, which have become the experimental animal of choice for many pulmonary disease studies. We evaluated the usefulness of micro CT for evaluating lung fibrosis in the murine model of bleomycin-induced lung inflammation and fibrosis. Methods: The control mice (n=10) were treated with saline. The murine model of lung fibrosis (n=60) was established by administering bleomycin intra-tracheally. Among the 70 mice, only 20 mice had successful imaging analyses. We analyzed the micro CT and pathological findings and examined the correlation between imaging scoring in micro CT and histological scoring of pulmonary inflammation or fibrosis. Results: The control group showed normal findings on micro CT. The abnormal findings on micro CT performed at 3 weeks after the administration of bleomycin were ground-glass opacity (GGO) and consolidation. At 6 weeks after bleomycin administration, micro CT showed various patterns such as GGO, consolidation, bronchiectasis, small nodules, and reticular opacity. GGO (r=0.84) and consolidation (r=0.69) on micro CT were significantly correlated with histological scoring that reflected pulmonary inflammation (p<0.05). In addition, bronchiectasis (r=0.63) and reticular opacity (r=0.83) on micro CT shown at 6 weeks after bleomycin administration correlated with histological scoring that reflected lung fibrosis (p<0.05). Conclusion: These results suggest that micro CT findings from a murine model of bleomycin-induced lung fibrosis reflect pathologic findings, and micro CT may be useful for predicting bleomycin-induced lung inflammation and fibrosis in mice.
