Segmental intestinal dilatation is rare, which causes symptom of bowel obstruction and requires resection. The resection is not only diagnostic but also curative procedure. Recently, author experienced 2 cases of segmental dilatation of the ileum due to focal agenesis of the intestinal muscularis in 7 day & 4 day-old female neonates. The post operative recovery was excellant in the first case after resection of dilated ileum(15cm in length) and end to end anastomosis, and discharged at 20th day. But in the second case, the passage disturbance was not relieved after resection of dilated ileum (30cm in length), and author re-resected 80cm more of dilated proximal ileum at 2 weeks after the first operation. This baby discharged after diarrhea control with Loperin on 1 month after the second operation. Final histologic examination showed 1) normal population of ganglion cells in both narrowed & dilated ileum in both cases. 2) focal abscence of muscularis propria in both cases. 3) relative hypertrophy of inner circular muscle layer and thinned, multiple fragmented outer longitudinal muscle layer in case 2.

Acute phlegmonous esophagitis (APE) is a rare and fatal disease. Phlegmonous infection involves the submucosal layer and muscularis propria but not the mucosal layer. Because surgery is not the first treatment option for this disease, an accurate diagnosis is crucial. Herein, we report three cases of APE with various clinical features. All patients were successfully treated with antibiotics and appropriate medical procedures.

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.

HD 환아 26례에서 시행한 37번의 직장흡인생검을 ACHE 조직화학검사한 결과 신생아형으로 판명된 16례 전례가 생후 1달 이내 검사한 경우였다. 혼합형으로 판명된 11례 중 9례가 2개월에서 12개월 사이에 검사한 경우였으며 고전형으로 판명된 9례 중 생후 3개월 부터 12개월 사이에 검사한 경우가 6례 였으며, 나머지 3례는 모두 1년 이후에 검사한 경우였다. 위의 결과로 보아 ACHE 조직화학검사에서 콜린성 신경섬유의 형태와 분포가 시간이 지남에 따라 변화함을 알 수 있다. 다시 말해서 신생아시기에 점막근층 및 이의 직하부 점막하층에 산재한 비교적 굵은 콜린성 신경섬유가 나이가 많아 짐에 따라 점점 가늘어 지면서 고유판과 점막하층에 광범위하게 분포하게 된다. 따라서 연령에 따른 ACHE 조직화학검사양상의 변화를 알고 이를 HD 진단에 응용함으로 Meier-Ruge등의 전통적인 진단기준으로 야기되는 오류를 극복할 수 있으리라 생각된다.

한국산 칼납자루의 암컷은 산란시기가 되면 배지느러미 기부 부근에 돌출되어 신장되어 나타나는 배측융기가 형성된다. 이러한 배측융기는 직장(항문)부분과 내측산란관으로 구성되었다. 직장은 점막층, 점막하층, 근육층과 이들을 둘러싸는 다층의 표층으로 구성되어 있으며 특히 점막층에는 산성 점액다당류인 점액세포가 존재한다. 한편 내측산란관은 직장과 비슷한 구조를 가지고 있으나 점막층에는 점액세포가 존재하지 않는 특징을 보였다. 한편 외측산란관은 배측융기와 연결되지 않아 가늘고, 긴 관의 형태를 보이고 있으나 내측산란관과 달리 근육층이 존재하지 않아 점막층, 점막하층, 다층의 표피층으로 구성되어 있다. 이러한 결과로 보아 근육층을 가지는 내측산란관은 성숙란을 외측산란관으로 내보기 위해 연동운동과 관련있는 반면에 외측산란관은 근육층이 존재하지 않아 내측산란관으로부터 방출된 성숙란을 단지 이매패 속으로 전달하는 단순한 관의 역할을 하는 것으로 생각된다.

Esophageal duplication cysts are uncommon, benign lesions of the esophagus. They are rare congenital foregut anomalies. To be considered an esophageal duplication cyst, a lesion must meet the following criteria:1 the cyst in the esophageal wall 2 the cyst is covered with a muscularis propria,generally of two layers and 3 the cyst has an epithelial lining consistent with that of the 4 week embryo, which may be columnar or pseudostratified columnar, and may be ciliated. Herein we report a case of an esophageal cyst located within the thoracic cavity, which is, to the best of our knowledge, the first case reported in Korea. Surgery is generally the treatment of choice for esophageal cyst, and was indicated in this case for the diagnosis and management of symptoms attributable to the cyst.

APUD cells in the oviduct of the sheep at standing estrus were localized as paraneurons in the lamina propria sandwiched between this structure and the tunica muscularis by the method of masked metachromasia to toluidine blue after hot mineral acid hydrolysis. These were also confirmed by lead haematoxylin stain and argyrophilia. The oviduct was serialized into 66 zones. Cells were absent in the first and last 2 zones, and most parts of the isthmus. There was however abundant number of APUD cells in the ampulla which were fusiform shaped and were about $5{\mu}m$ width and also in the juncture, where the cells were of a smaller width ($3{\mu}m$) and were quite numerous reaching 180-200 in some zones. It is concluded that peptide secreting cells are numerous in the oviduct and that this may qualify the oviduct as an endocrine organ.

The development of esophagus in fetuses between 60, 90, 120 days of gestation and neonates of Korean native goats was investigated by light, scanning electron microscopy. The results were summarized as follows; 1. The esophageal wall appeared to be differentiated into the epithelium, lamina propria, tunica muscularis and tunica adventitia at 60 days of gestation. The esophageal epithelium was stratified cuboidal at 60 days, being transformed into stratified squamous epithelium at 90 days, and completely transformed into squamous epithelium an 120 days. 2. In scanning electron microscopy, the longitudinal furrows and ridges appeared on the epithelium of the esophagus of the fetuses at 60 days of gestation. The longitudinal furrow became deeper and microplicae appeared in 90-day-old fetuses. The transverse and longitudinal folds appeared on the epithelial surface of esophagus and the esophageal epithelium started to be keratinized in the neonates.

Plexiform fibromyxoma (PF) of the stomach is a very rare mesenchymal tumor of the gastrointestinal tract. We report the first case of PF with 2 different growth patterns pathologically confirmed after surgical resection. The tumor was characterized microscopically as infiltrative; it demonstrated diffuse growth into the smooth muscle bundles of the muscularis propria and was also multinodular and plexiform within the myxoid stroma. Immunohistochemical analysis revealed that the tumor cells were positive or weakly positive for smooth muscle actin, vimentin, and H-caldesmon and negative for desmin, CD117, CD34, CK-20, Pan-CK, Dog1, S100, ER, PR, and CD10. No mutations of C-kit and platelet-derived growth factor receptor alpha were detected. No genetic disruption of glioma-associated oncogene homolog 1 was detected by fluorescence in situ hybridization. The final diagnosis of PF was mainly based on the morphological and immunohistochemical findings.
