Bullae-Forming Pulmonary Metastasis from Choriocarcinoma Presenting as Pneumothorax
현관용,전현우,김경수,최국빈,박재길,박형주,왕영필 대한흉부외과학회 2015 Journal of Chest Surgery (J Chest Surg) Vol.48 No.6
Gestational trophoblastic disease (GTD) is a condition of uncertain etiology, choriocarcioma, or placental-site hydatidiform moles, invasive moles, choriocarcinoma, and placental-site trophoblastic tumors. It arises from the abnormal proliferation of trophoblastic tissue and spreads beyond the uterus hematogenously. The early diagnosis of GTD is important to ensure timely and successful management and the preservation of fertility. We report the unusual case of a metastatic choriocarcinoma that formed bullae on the lung surface and presented as recurrent pneumothorax in a 38-year-old woman with elevated beta-human chorionic gonadotropin (hCG) levels. She underwent thoracoscopic wedge resection of the involved lung and four subsequent cycles of consolidation chemotherapy. No other evidence of metastatic disease or recurrent pneumothorax was noted during 22 months of follow-up. GTD should be considered in the differential diagnosis of spontaneous pneumothorax in reproductive-age women with an antecedent pregnancy and abnormal beta-hCG levels.

1) During 5 month (Oct. 1988-Feb. 1989), abortion (11 heads), stillbirth (3 heads), and congenital abnorrnalities(28 heads) of newborn were occurred in 42 milk cows raised in Cheju island. These cows were diagnosed with Akabane disease by clinical, pathological and serological test. 2) In May and Oct. 1989, 213 cattles at 10 farms were investigated on the actual condition of possessing Akabane antibody. The results was that 210 heads(98.6%) in 213 cattles reacted as positive condition in Akabane antibody. The antibody titer was from 4 to over 256. 3) During some years, the auther suppose that the vaccination for Akabane disease will be unnecessary because of higher positive antibody reaction except the newly introduced cattle.
Atypical Thymic Carcinoid in a Patient with Zollinger-Ellison Syndrome
이지윤,현관용,문미형,문석환,박재길,최시영,사영조,김경수 대한흉부외과학회 2019 Journal of Chest Surgery (J Chest Surg) Vol.52 No.6
Atypical thymic carcinoid is an extremely rare tumor with a poor prognosis. In addition to its known association with multiple endocrine neoplasia type 1, its hallmark characteristics include local invasion and early distant metastasis. In this report, we share our experience treating atypical thymic carcinoid in a patient with Zollinger-Ellison syndrome.
濟州道 雜犬의 繁殖生理에 關한 硏究 : 發情 持續期間에 對하여
吳文儒,金永洪,玄寬宗 제주대학교 1976 논문집 Vol.8 No.-
An observation was made on the duration of estrus and the blood values during the estrous cycles in 15 mongrel bitches. The results obtianed were as follows ; 1. The length of proestrus was reckoned up the time from first appearance of blood in the vaginal smears to first acceptance of the male; varied 4 to 12 days (mean±S.D.=7.8±2.6 days). 2. The duration of estrus was determined by the acceptance test following the days between first and last acceptance; varied from 4 to 13 days (8.1±2.6 days). 3. The duration of visible bieeding out of vigina varied from 12 to 23 days (16.9±2.6days). 4. The seasonal occurrence of estrus did not exhibit. 5. During proestrus and estrus, the erythrocyte numbers increased 5-6% above those of established for beagle in anestrus. No significant variation in total leucocyte numbers was noted during the estrous cycles.
Single Incision Thoracoscopic Left Lower Lobe Superior Segmentectomy for Non-Small Cell Lung Cancer
전현우,최수환,현관용,왕영필 대한흉부외과학회 2014 Journal of Chest Surgery (J Chest Surg) Vol.47 No.2
Lobectomy with mediastinal node dissection has been standard treatment for non-small cell lung cancer (NSCLC). Nowadays, video-assisted thoracoscopic surgery (VATS) is gaining acceptance as an alternative treatment option, given the quality-of-life benefits that it confers. For the VATS procedure, most surgeons create two or three ports with a utility incision of 3 to 5 cm. However, with acquired skill and instrumentation advances, single-incision thoracoscopic surgery has emerged over time. Here, we report the case of an 86-year-old female with NSCLC treated by single-incision segmentectomy.
The Significance of Serum Carcinoembryonic Antigen in Lung Adenocarcinoma
김재준,박재길,현관용,문석환 대한흉부외과학회 2015 Journal of Chest Surgery (J Chest Surg) Vol.48 No.5
Background: A raised carcinoembryonic antigen (CEA) may be associated with significant pathology during the postoperative follow-up of lung adenocarcinoma. Methods: We reviewed the medical records of 305 patients who underwent surgical resections for primary lung adenocarcinoma at a single institution between April 2006 and February 2013. Results: Preoperative CEA levels were significantly associated with age, smoking history, pathologic stage including pT (pathologic tumor stge), pN (pathologic nodal stage) and overall pathological stage, tumor size and differentiation, pathologically positive total lymph node, N1 and N2 lymph node, N2 nodal station (0/1/2=1.83/2.94/7.21 ng/mL, p=0.019), and 5-year disease-free survival (0.591 in group with normal preoperative CEA levels vs. 0.40 in group with high preoperative CEA levels, p=0.001). Preoperative CEA levels were significantly higher than postoperative CEA levels (p<0.001, Wilcoxon signed-rank test). Postoperative CEA level was also significantly associated with disease-free survival (p<0.001). A follow-up serum CEA value of >2.57 ng/mL was found to be the appropriate cutoff value for the prediction of cancer recurrence with sensitivity and specificity of 71.4% and 72.3%, respectively. Twenty percent of patients who had recurrence of disease had a CEA level elevated above this cutoff value prior to radiographic evidence of recurrence. Postoperative CEA, pathologic stage, differentiation, vascular invasion, and neoadjuvant therapy were identified as independent predictors of 5-year disease- free survival in a multivariate analysis. Conclusion: The follow-up CEA level can be a useful tool for detecting early recurrence undetected by postoperative imaging studies. The perioperative follow-up CEA levels may be helpful for providing personalized evaluation of lung adenocarcinoma.

We report a case of an entrapped lung after the pectus bar repair of a pectus deformity. The entrapped lung was found incidentally during video-assisted thoracoscopic surgery (VATS) for pneumothorax. Based on VATS exploration, multiple bullae seemed to be the cause of the pneumothorax, but the entrapped lung was suspected to have been a cause of the air leakage.
