Ectopic thyroid gland is a defined as thyroid tissue located in a site other than its usual pre-tracheal location. Ultrasound examination, CT scan, thyroid scan, and thyroid iodine uptake test are all valuable modalities for a differential diagnosis. Although most of cases are asymptomatic, treatment is indicated when there are symptoms related to progressive growth of mass. This article reports a ectopic thyroid cyst in the anterior neck that was similar to deep neck infection accompanied by acute airway obstruction.

We report here an ectopic case of Fasciola hepatica infection confirmed by recovery of an adult worm in the mesocolon. A 56-year-old female was admitted to our hospital with discomfort and pain in the left lower quadrant of the abdomen. Abdominal CT showed 3 abscesses in the left upper quadrant, mesentery, and pelvic cavity. On surgical exploration, abscess pockets were found in the mesocolon of the sigmoid colon and transverse colon. A leaf-like worm found in the abscess pocket of the mesocolon of the left colon was diagnosed as an adult fluke of F. hepatica. Histologically, numerous eggs of F. hepatica were noted with acute and chronic granulomatous inflammations in the subserosa and pericolic adipose tissues. Conclusively, a rare case of ectopic fascioliasis has been confirmed in this study by the adult worm recovery of F. hepatica in the mesocolon.

Infection of Drosophila melanogaster adults with 6 Vibrio species revealed that V. cholerae was lethal (100% mortality) within 20 h as a result of systemic infection. Avirulent infection by V. vulnificus restricted the subsequent virulent infection by V. cholerae. The immediate transcription of antimicrobial peptides (AMPs), most notably Attacin A, was delayed in V. cholerae infection compared to V. vulnificus infection. Ectopic expression of Attacin A and Metchnikowin enhanced the survival of D. melanogaster upon V. cholerae infection. These results suggest that AMPs are important in the response to infections by Vibrio species and that the signaling pathways governing their expression may be targeted by V. cholerae virulence factors to elude the innate immunity of Drosophila.

Small cell lung cancer (SCLC), which originated from neuroendocrine tissue, can develop into paraneoplastic endocrine syndromes, such as Cushing syndrome, because of an inappropriate secretion of ectopic adrenocorticotropic hormone (ACTH). This paraneoplastic syndrome is known to be a poor prognostic factor in SCLC. The reason for poor survival may be because of a higher risk of infection associated with hypercortisolemia. Therefore, early detection and appropriate treatment for this syndrome is necessary. But the diagnosis is challenging and the source of ACTH production can be difficult to identify. We report a 69-year-old male patient who had severe hypokalemia, metabolic alkalosis, and hypertension as manifestations of an ACTH-secreting small cell carcinoma of the lung. He was treated with ketoconazole and spironolactone to control the ACTH dependent Cushing syndrome. He survived for 15 months after chemotherapy, which is unusual considering the poor outcome of the ectopic ATH syndrome associated with SCLC.

이소맹출은 치아가 비정상적인 위치나 방향으로 맹출하는 것으로 정의되며 구치부에서는 근심측으로 맹출하여 인접치아의 치근 흡수나 조기 탈락을 야기하여 공간 상실을 일으킬 수 있고, 부분 맹출된 경우 치은 하방의 치아우식 위험성이 증가하고 농양을 형성할 수도 있다. 구치부의 이소맹출 가운데 66% 정도는 가역적인 경우로 특별한 치료 없이 자연적으로 정상적인 맹출이 일어나며, 비가역적인 이소맹출의 경우에는 치아의 맹출 상태, 인접치에 의해 매복된 양, 인접치의 동요도, 통증이나 감염 여부 등의 여러 요인을 고려하여 본격적인 치료가 필요하다. 본 논문에서는 비가역적으로 이소맹출된 상악 제1대구치와 하악 제2대구치를 치간이개 고무줄, modified Halterman appliance 그리고 외과적 노출 후 modified Halterman appliance를 이용한 방법 등으로 정상적인 맹출을 유도한 증례를 보고 하는 바이다.

Purpose: Paragonimiasis is infectious disease occurred by Paragonimus Westermani, which invades into human body as a final host. Habitual eating the freshwater crab or crawfish unboiled is one of the reason of infection. Paragonimiasis raged in 1970s in Korea, Japan, China and other Asian countries but the incidence decreased rapidly. Once people eat infected second host, parasite penetrates the duodenal wall and migrates to the lung. During this migration period, the parasite can migrate to other organ, such as brain, spinal cord, liver and subcutaneous tissue, but the cases are rarely reported. The objective of our study is to present our experience of the ectopic migration of parasite to the subcutaneous tissue of the abdomen, which was easily treated with excision and Praziquantel medication. Methods: A 59-year-old woman who likes eating unboiled freshwater crab was diagnosed as Paragonimiasis 15 months ago. Her symptoms were fever and cough, and she was treated with Praziquantel medication. 3 months after discharge, she visited our hospital with left pleuritic chest pain, cough with fever, and palpable mass formation on left lower quadrant of the abdomen. Wedge resection of the left lung and Praziquantel medication was maintained for a week. Nevertheless, fever persisted after the treatment. The patient received total excision of the abdominal soft tissue mass, and the fever was relieved. Results: Pathologic findings of the mass showed multiple cyst and abscess formation with crystal structure which is suspicious parts of the parasite or calcified egg shells. Uncontrolled fever was relieved after the operation, and there was no evidence of recurrent Paragonimiasis and ectopic migration for 1 year follow up period. Conclusion: Ectopic migration of Paragonimus is rare, but multiple organ can be involved. Patient with Paragominiasis who was refractory in fever control after Praziquantel medication or surgical evaluation of the lung should be considered as ectopic migration of the Paragonimiasis.

3세의 암컷 닥스훈트견이 뒷다리의 부전마비와 사지냉감을 주증으로 본원에 내원하였고 진단을 위해 병력청취, 신체검사, 신경계 검사 및 혈액검사를 실시하였다. 복부 및 심장 초음파 검사 결과, 심장사상충의 성충으로 의심되는 소견이 정상 기생부위 이외의 장소에서 관찰되었다. 효소면역측정법을 이용한 심장사상충 항원 키트 검사 결과 양성반응이 확인되었다. 환자는 입원 당일 혼수상태에 빠져 보호자의 요청으로 안락사 되었다. 보호자의 동의 하에서 실시된 사후 부검 결과 심장의 4방과 대동맥, 복대동맥 및 엉덩동맥에서 높은 충체 부하의 심장사상충 성충이 확인되었으며, 이로 인한 다량의 전신성 혈전색전증 또한 관찰되었다. 본 증례에서는 전신 순환계로의 개 심장사상충 이소기생의 임상적 특징과 진단 영상 및 사후 부검 결과를 소개하였다.

조직학적으로 진단할 수 있는 인체 기생충증의 종류 및 감염양상에 대하여 알아보고자 1980년부터 1989년까지 10년 동안 전남대학교병원 병리과에 통상적인 조직검사가 의뢰된 80,947례 중 기생충 감염으로 진단된 149례(0.18%)를 대상으로 본 조사를 시행하였다. 조직학적으로 진단된 기생충증은 낭미충증 112례. 례흡충증 17례. 간흡충증 7례. 아메바증 4례. 간질증 스파르가눔증. 요충증 및 아니사키스증 각각 1례 등이었다. 낭미충증은 여성에서 약간 많았으며. 연령별 감염빈도는 20대에서 가장 높았고, 주로 침범하는 부위는 피하조직 및 골격근이었다. 절편상에서 충체가 확인된 94례의 낭미충증은 형태적인 보존정도로 보아 19례(20.2%)에서는 거의 변성이 없었고, 중등 도변성 38례(40.4%). 고도변성 37례(39.4%)를 보였다 폐에 기생한 2례를 제외한 15례의 이소기생 폐흡충은 복강(8례)과 중추신경계(7례)에 분포하였고, 20대 및 30대에서 가장 호발하였으며. 남성에서의 감염이 73.3%로 많았다. 담관내 간질증은 국내 13번째 인체감염례에 해당된다. 조직학적으로 진단되는 기생충증의 빈도는 연도가 경과할수록 점차 감소하고 있었으나, 낭미충증과 이소기생 폐흡충증에서는 생검이 매우 유용하게 이용되는 진단 방법임을 알 수 있었다.

Ectopic expression of CDX2 in the stomach is closely associated with chronic Helicobacter pylori (H. pylori) infection and intestinal metaplasia. Whether CDX2 has tumor suppression or tumorigenesis potential remains to be elucidated. In this study, we investigated the association between the CDX2 G543C polymorphism (silent mutation) and the risk for H. pylori-induced gastric atrophy and cancer as well as H. pylori infection, using 454 Japanese subjects undergoing a health checkup and 202 gastric cancer patients. The frequency of the minor allele was the same as previously reported in China, but different from that reported in England. CDX2 G543C was not associated with risk of H. pylori infection, gastric atrophy, or gastric cancer, although the point estimate for non-cardiac differentiated gastric cancer as compared to controls with gastric atrophy was 2.22 (95%CI=0.17-29.4). In conclusion, our results indicate that the CDX2 G543C polymorphism is unlikely to affect the H. pylori infection-gastric atrophy-gastric cancer sequence.

서울에 거주하는 32세 가정주부가 좌하측 흉벽에 발생한 직경 약 3cm인 종괴를 제거하기 위하여 입원하였다. 종괴는 지난 3개월간 네번 켜졌다가 없어지고는 하였다. 수술 소견상 전거상근(전거상근)내에 육아종이 있었고 그 안에서 미성숙 간질 충체를 발견하였다. 이 증례를 우리나라의 인체 간질 감염 제11례로 보고한다. 간질의 이소기생중 가장 흔한 것으로 알려진 피하기생례로는 우리나라에서는 처음으로 경칩한 중례이며 앞으로 기생충성 피하종괴의 감별대상에 간질(간질) 감염도 고려하여야 한다고 생각한다.
