The effect of methamphetamine on the pulmonary metastasis was investigated in C57BL/6 mice injected with Bl6 melanoma cells. Bl6 melanoma cells (2$\times$10$^{5}$ cells) were injected intravenously into 5~7 weeks old C57BL/6 mice. Mice were then treated intraperitoneally with methamphetamine either acutely (two times with one week interval) or subchronically (daily for 14 days). Degree of pulmonary metastasis was investigated and specific immunologic parameters such as natural killer cell cytotoxicity(NKCC), antibody-dependent cellular cytotoxicity(ADCC) and blastogenic responses of splenocytes were examined. Mice which had been subchronically treated with methamphetamine showed significant decreases in the number of pulmonary metastasis of Bl6 melanoma cells, NKCC and ADCC without a significant change in blastogenic responses. In the acutely-treated group, slight trends of decrease in the numbers of pulmonary metastasis, NKCC and ADCC were observed without statistical significances whereas there was a significant increase in blastogenic responses. The mechanism underlying the decrease in the degree of metastasis despite diminished NKCC and ADCC after methamphetamine treatment and the relationship between the degree of pulmonary metastasis and duration of methamphetamine treatment remain to be investigated.

임신성 융모상피암은 임신으로 생성되는 영양아 세포에서 기원하는 악성도가 높은 암이다. 이 암은 초기에 폐 전이를 일으키며, 폐 전이는 경계가 명확한 수개의 결절형태로 나타나는 것이 가장 흔하다. 그러나 간혹 고립성 폐전이를 일으켜 진단이 어려울 때가 있다. 저자들은 각각 일측폐의 전체, 동전양 병변, 괴사성 종양의 소견을 보인 세유형을 보고하며 융모성 질환의 발생빈도가 높은 지역에서는 여성의 고립성 폐병변의 감별에서 산부인과 병력과 융모성 성선자극 호르몬 측정의 중요성을 강조한다.

Metastasis of lung cancer to the skin is uncommon, presenting in 0.22% to 12% of lung cancer patients, and it is extremely rare for skin metastasis to be the first clinical manifestation of lung cancer. In the few cases where skin metastasis has been reported as the first sign of lung cancer, the patients were typically heavy smokers or had preexisting respiratory diseases and symptoms. This prompted clinicians to consider skin metastasis of a pulmonary malignancy. Large cell neuroendocrine carcinoma (LCNEC) is a rare type of lung cancer that accounts for approximately 3% of lung cancers. LCNEC mainly metastasizes to visceral organs, such as the liver, bone, and brain, and it only shows metastasis to the skin in very rare cases. Herein, we report an unusual case of a metastatic skin lesion as the first sign of primary pulmonary LCNEC, in a 63-year-old woman with no pulmonary symptoms or personal history of smoking or pulmonary disease.

1991년 3월부터 1995년 3월까지 영남대학교 의과대학 부속병원 내과에서 입원해서 혈청학적, 방사선학적 및 조직학적으로 간세포함으로 진단받은 156명의 환자 중 진단당시부터 폐전이를 동반한 12명(7.7%)을 제외한 144명의 환자를 대상으로 최소한 5개월 이상을 추적관찰하여 폐전이를 동반한 경우와 동반하지 않은 경우로 나누어 나이, 성별, Child-Pugh 점수, 간경변증 동반유무, AFP치 및 간동맥 색전술여부 등을 조사하여 그 차이점을 비교 분석하여 다음과 같은 결과를 얻었다. 추적관찰 중 폐전이를 동반한 경우가 26례(18.0%)였는데 간동맥 색전술을 시행한 경우가 26례 중 24례(92.3%), 시행하지않은 경우가 26례 중 2례(7.7%)였다. 폐전이를 동반하지 않은 118례 가운데 간동맥 색전술을 시행한 경우가 78례, 시행하지 않은 경우가 40례였다. 따라서 간동맥 색전술 시행후 폐전이를 동반한 경우가 102례 중 24례(23.5%), 간동맥 색전술을 시행하지 않고 폐전이를 동반한 경우가 42례 중 2례(4.7%)로 나타나서 간동맥 색전술 이후 폐전이가 더 빈번함을 알 수 있었다(p<0.01). 그러나, 나이, 성별, Child-Pugh 접수, 간경변증 동반유무 및 AFP치는 차이를 보이지 않았다. 결론적으로 간세포암에서 간동맥 색전술 이후 폐전이가 보다 많이 동반됨을 알 수 있었고 이에 관련되는 근본적인 설명과 그외 관련인자들에 대한 보다 많은 연구가 필요할 것으로 사료된다.

Matrix metalloproteinases (MMPs) are capable of degrading extracellular matrix, a process that is necessary for angiogenesis, tumor invasion and metastasis. Platelet-activating factor (PAP) increases angiogenesis, tumor growth and metastasis through nuclear factor (NF)-$\kappa$B activation. Based on these facts, the involvement of MMPs in PAF-induced pulmonary metastasis was investigated in murine sarcoma cells, MMSV-BALB/3T3. Messenger RNA expression and enzymatic activity of MMP-9 were assessed by RT-PCR and zymography, and cell migration and metastasis were done for the detection of MMP-9 functional activity. PAP induced mRNA expression and enzymatic activity of MMP-9, and its effects were either inhibited by the PAP antagonist, WEB 2170 or by the NF-$\kappa$B inhibitor, parthenolide, or p65 antisense oligonucleotide in a dose-dependent manner. In addition, PAF induced promoter activity of MMP-9, which was inhibited by WEB 2170, phenanthroline, NAC, PDTC. These results indicate that PAF induces mRNA expression and enzymatic activity of MMP-9 in NF-$\kappa$B dependent manner. Cell migration assay showed that PAF induced MMSV-BALB/3T3 migration, and its effect was significantly inhibited by treatment with phenanthroline. PAF enhanced pulmonary metastasis of murine sarcoma cells, MMSV-BALB/3T3 was also reduced by phenanthroline. These results suggest that PAF-enhanced cell migration and pulmonary metastasis is mediated through the expression of MMP. In conclusion, It is suggested that PAF enhances pulmonary metastasis by inducing MMP-9 expression via the activation of NF-$\kappa$B.

Epithelioid sarcomas are rare soft tissue sarcomas with a high tumor grade and high local recurrence and metastasis rates. Although the lung is the most common site of metastasis, endobronchial metastasis hasn't been reported yet. We now report a case of epithelioid sarcoma with endobronchial metastasis. A 28-year-old man had recurrent pneumothorax and underwent wedge resection. He presented at our hospital with hemoptysis, dyspnea, and chest pain. Chest computed tomography revealed left pneumothorax, multiple lung nodules and endobronchial lesions at the right lower basal lobe. Bronchoscopy showed a hemorrhagic mass obstructing the bronchus of the right lower basal lobe. Magnetic resonance imaging revealed multiple nodular lesions in the left thigh muscles. The bronchoscopic biopsy of the endobronchial lesion and the muscle biopsy of the thigh showed the same feature epithelioid sarcoma. This is the first case report of an epithelioid sarcoma with endobronchial metastasis that was diagnosed by bronchoscopic biopsy.

거대 세포종은 일반적으로 양성 골종양이지만 드물게 폐로 전이하는 특성이 있다. 임상적으로 거대 세포종의 폐 전이는 지속적으로 진행하기도 하지만 종종 스스로 성장이 정지하거나 또는 자연 소실되는 경우도 있는 것으로 알려져 있다. 저자들은 거대 세포종의 광범위한 폐전이가 자연 소실된 예를 경험하여 보고하고자 한다.

Background: Treatment of pulmonary metastasis from urothelial cell carcinoma has been mostly palliative chemotherapy and the role of pulmonary metastasectomy has not been investigated much. Materials and Methods: This study is a retrospective interim review of pulmonary metastasectomy from urothelial carcinoma at single institution between 1998 and 2010. Overall 16 patients underwent pulmonary metastasectomies. Results: There was no postoperative complication or hospital mortality. Mean hospital stay was 6 days. Overall and disease-free 5-year survival were 65.3% and 37.5%, respectively. Conclusion: In selected patients with pulmonary metastasis from urothelial carcinoma, surgical treatment is feasible and could contribute to long-term survival in selected patients.

정맥내 평활근종증은 자궁근육이나 혈관벽에서 발생한 평활근종이 정맥로를 통해 확장되어, 조직학적으로는 양성이나 임상적으로는 악성 경과를 취하는 매우 드문 질환이다. 종양은 대부분 정맥을 통로로 하공정맥, 우심방, 우심실, 심지어 폐동맥까지 확장되어 우심장의 폐쇄를 일으키면서 증상을 나타내는 것으로 되어 있으나, 매우 드물게 폐전이도 일으키는 것으로 보고되고 있다. 자궁에서 발생한 정맥내 평활근종이 우심실까지 확장되어 우심 폐쇄의 증상과 폐전이를 일으킨 53세의 여자 환자를 수술 치험하였기에 문헌고찰과 함께 보고한다.

A 9-years female Pointer with a 5 cm opened mammary mass in the 4th right mam-mary gland was referred to the Veterinary Teaching Hospital, Chungnam National University. Any abnormal sign was not found in physical examination. But there were leukocytosis, neutrophilia, and monocytosis. Values of RBC, hemoglobin, and hematocrit were low in hematologic examination. Several “cannon-ball” like nodules and pulmonary interstitial pattern were found in the thoracic radiogram. Histopathologically, proliferation of epithelial cells and myoepithelial cells and cartilage tissues were found in the mammary gland mass and infitration of spindle myoepithelial tumor cells was observed in pulmonary nodules. This dog was diagnosed as mammary mixed tumor with Pul- monary metastasis.
