Esophageal granular cell tumor (GCT) is a rare neoplasm originating from the Schwann cells of the submucosal neuronal plexus. Histology is the gold standard for its diagnosis. Endoscopic resection or surgical excision should be considered, depending on the potential for malignancy. Here, we report a case of an esophageal GCT in an adolescent. A 12-year-old boy presented with a 1-year history of dysphagia and vomiting. Upper gastrointestinal endoscopic examination and esophagography showed narrowing of the midesophagus, and computed tomography angiography of the thoracic aorta revealed an esophageal or periesophageal mass posterior to the paratracheal segment of the esophagus. The tumor was surgically excised, and based on the pathological findings, esophageal GCT was diagnosed.

전신 부종을 주소로 내원한 20개월된 남아에서 대변의 ${\alpha}_1$-antitrypsin clearance를 이용하여 단백상실성 장병증으로 진단하고, 상부위장관내시경을 시행하였으나 육안적 및 조직학적 소견상 특기할 만한 진단적 실마리가 관찰되지 않아, 고지질 식이를 투여 후 내시경을 시행하여 육안적, 조직학적 소견상 장림프관 확장증의 특징적인 소견이 확인되어 원발성 장림프관 확장증으로 진단된 증례이다.

현대의학의 발달에 따라 병인을 규명하기 위하여 세밀한 관찰과 자료획득이 가능한 각종 내시경이 대두되기에 이르렀다. 이의 일종인 내시경적 성대경으로 종래에는 보기 힘들었던 병변의 관찰은 물론 사진촬영이 동시에 이루어질 수 있어서 병변의 조기발견과 함께 귀중한 자료가 얻어질 수 있게 되었다. 과거 5년 동안 이화여자대학교 의과대학 부속병원 이비인후과 외래에서 시행한 성대경 사용경험에 따른 장단점과 사진촬영으로 얻은 자료를 중심으로 그 결과를 보고하는 바이다. 1) 간접후두경으로 관찰하기 힘들었던 병변을 보다 명확하게 관찰할 수 있었다. 2) 사진촬영 결과를 환자에게 제시할 수 있어서 치료전후의 상태를 확인시킬 수 있었다. 3) 확대된 성대상을 관찰할 수 있어서 미세한 병변의 감별이 용이하였다. 4) 성대관찰시간이 단축되고 조작이 간편하여 외래에서 사용하기 편리하였다.

Objective: To summarize the endoscopic screening findings in high-risk population of esophageal and gastric carcinoma and analyze influential factors related to screening. Methods: In seven selected cities and counties with high incidences of esophageal carcinoma, people at age of 40-69 were set as the target population. Those with gastroscopy contradictions were excluded, and all who were voluntary and willing to comply with the medical requirements were subjected to endoscopic screening and histological examination for esophageal, gastric cardia and gastric carcinoma in accordance with national technical manual for early detection and treatment of cancer. Results: In three years, 36,154 people were screened, and 16,847 (46.60%) cases were found to have precancerous lesions. A total of 875 cases were found to have cancers (2.42%), and among them 739 cases had early stage with an early diagnosis rate is 84.5%. Some 715 patients underwent prompt treatment and the success rate was 81.8%. Conclusions: In a high-risk population of esophageal and gastric carcinoma, it is feasible to implement early detection and treatment by endoscopic screening. Screening can identify potential invasive carcinoma, early stage carcinoma and precancerous lesions, improving efficacy through early detection and treatment. The exploratory analysis of related influential factors will help broad implementation of early detection and treatment for esophageal and gastric carcinoma.

저자들은 정신 지체를 가진 병적 공기 연하증환자를 임상 증상과 단순 흉부 X-선 사진상의 '식도 내 공기 징후'와 투시진단법으로 진단하여 보고하는 바이며, 본 증례와 같이 장기적으로 호전을 보이지 않는 공기 연하증 환자에서 조기에 PEG를 시행하여 공기를 빼내는 도구로 이용하면, 심각한 합병증의 발생을 예방할 수 있을 것으로 판단된다.

Aims and Background: To improve understanding of the relationship between schistosome-related enteropathy and colorectal carcinoma with particular focus on endoscopic findings and clinicopathological characteristics of colonic schistosomiasis. Materials and Methods: All cases of intestinal schistosomiasis diagnosed at West China Hospital, Chengdu, China, between October 2006 and October 2012 were included in this study. A total of 179 cases of colonic schistosomiasis diagnosed through colonoscopy and pathological examinations were collected for analysis and the demographics, symptoms, endoscopic findings and clinicopathological characteristics were retrospectively evaluated. Results: Of the 179 colonic schistosomiasis patients, 32 combined with colorectal cancer (CRC) were found, between the ages of 44 and 85 years (24 males, 75%). These 32 lesions were classified as 12 endophytic/ulcerative (37.5%), 10 exophytic/fungating (31.2%), 4 annular (12.5%), 3 giant polypus (9.4%), and 3 IIc (superficial depressed type) (9.4%). The segments of rectum and sigmoid colon were involved in 19 patients (59.4%) and 6 patients (18.8%), respectively. The histopathologic types were classified as follows: 30 welldifferentiated adenocarcinomas, one mucinous adenocarcinoma and one poorly differentiated adenocarcinoma. The pathological findings suggest colorectal malignancy with deposited schistosome ova. Conclusions: Chronic schistosomal infestation has a probable etiological role in promoting genesis of colorectal neoplasms.

Background: Genetic mutation is a significant factor in colon CA pathogenesis. Familial adenomatous polyposis (FAP) is an autosomal dominant hereditary disease characterized by multiple colorectal adenomatous polyps affecting a number of cases in the family. This report focuses on a family with attenuated familial adenomatous polyposis (AFAP) with exon 4 mutation, c.481C>T p.Q161X of the APC gene. Methods: We analyzed 20 members of a family with AFAP. Clinical and endoscopic data were collected for phenotype determination. Genetic analysis was also performed by direct sequencing of the APC gene. Result: Five patients with a phenotype of AFAP were found. Endoscopic polyposis was demonstrated among the second generation with genotype mutation of the disease (age > 50 years) consistent with delayed phenotypic adenomatous polyposis in AFAP. APC gene mutation was identified in exon 4 of the APC gene, with mutation points of c.481C>T p.Q161X. Laparoscopic subtotal colectomy was performed to prevent carcinogenesis. Conclusion: A family with attenuated familial adenomatous polyposis of APC related to exon 4 mutation, c.481C>T p.Q161X, was reported and the phenotypic finding was confirmed by endoscopic examination. Genetic mutation analysis might be advantageous in AFAP for long term colon cancer prevention and management due to subtle or asymptomatic phenotype presentation in early adulthood.

Human vocal cords vibrate as quickly as 100-250 times per second, so it is impossible to observe them with normal endoscopic diagnostic equipment. High-speed videolaryngoscopy (HSV) allows the visualization of non-periodic vibratory motion of vocal fold beyond the limitation of videostroboscopy. New developed post-processing methods that converts HSV to two-dimensional videokymography (2D VKG) using U-medical image-processing software can provide quantitative information on vocal fold mucosa vibration. Multifunctional laryngeal examination system is composed of 3 kinds of examinations such as HSV, 2D scanning digital kymography (2D DKG) and line scanning digital kymography (DKG). Evaluation of entire vocal cord vibratory pattern in each cord is possible using 2D DKG and a faster and more reliable quantitative information can be obtained. As this system is used in clinical and research, it is expected to bring much advances to the diagnosis of voice disorders. In this review, I will introduce the principles and advantages on examination of the vocal fold vibration, which is in the spotlight recently, and proceed with the literature review.

식도평활근종은 식도에 발생하는 양성종양 중에서 그 빈도가 가장 흔하지만, 식도에서 발생하는 모든 종양 중단지 1%를 차지할 정도로 비교적 흔치 않은 식도 질환이다. 식도평활근종은 식도근층에서 유래한 벽내 종양이 대부분을 차지하지만, 점막근층에서 유래하여 식도강내 육경을 가진 폴립과 유사한 형도 약 1%의 빈도로 드물게 보고된다. 최근에 30세 남자환자가 연하곤란을 주소로 본원에 입원하였다. 방사선학적 검사에서 직경 5cm의 강내 종양이 경부식도에서 발견되었다. 내시경검사에서 종양조직은 정상 점막으로 덮여 있음을 보였다. 좌측 경부절개를 통해 식도 전벽에 종절개를 가한 후 육경성 종양을 성공적으로 적출할 수 있었다. 조직학적 검사에서 식도 평활근종으로 확진되었다. 연하장애 등 합병증없이 술후 회복과정은 순조로웠다.

1995년 12월 2일 33세의 한국 여성이 성교 후 점상 출혈과 복통을 주소로 경상북도 구미시의 한 산부인과의원을 방1문하였다. 환자는 2회의 출산을 하였고. 7년 전 난관결찰을 시술 받은 바 있으며. 월경 시에는 요통이 있었다고 하였다. 환자 질 분비물은 악취가 났으나 가려움증을 호소하지는 않았다. 질의 후원개에서 채취한 검체 도말에서 요충란이 관찰되었다. 질 내시경으로 질의 후원개에서 살아있는 충체를 검출하였고. 형태학적 관찰에 의거하여 요충의 자충으로 동정하였다. 이 증례는 한국 성인 여성에서 발생한 요충의 질내 이소기생증의 제1례이다.
