Axillary lymph node schistosomiasis is a form of ectopic schistosomiasis, in which the Schistosoma adult worms or eggs are infected in the axillary lymph nodes. A 53-year-old woman visited our hospital with a small mass in the right armpit, which had been present for over 1 month. Histological examination of biopsy samples from the right axillary lymph nodes revealed granulomas containing calcified Schistosoma eggs. This is the first authentic case of ectopic schistosomiasis identified in the axillary lymph nodes.

In the embryo, the thymus originates from the third and fourth pharyngeal pouches and migrates from the superior neck to the mediastinum. Ectopic cervical thymoma (ECT) is an extremely rare tumor that originates from ectopic tissue, and is caused by the aberrant migration of the embryonic thymus. Our patient was a 30-year-old woman who had a nodular lesion in the neck for several years. Ultrasonography and computed tomography were performed. She underwent surgery, and a histological examination resulted in a diagnosis of type AB thymoma. Herein, we report a case of ECT that was resected through a transcervical approach.

Impacted third molars of the mandible are generally found at or close to the second molar. If the third molar is impacted far distant from its original site, it may be affected by cysts or tumors. Ectopic impaction of third molar in the condyle area is very rare. Furthermore, impaction without cystic lesion is even less common. The etiology of migration of the mandibular third molar without cystic lesion is unknown. So periodical X-ray taking is essential.

신장은 이소성 부신 선종의 드문 부위이다. 우리가 아는 한, 신장에서 발생한 이소성 부신 선종의 일부 증례가 보고되었지만, 이러한 증례들 중 병변의 컴퓨터단층촬영 및 자기공명영상소견을 설명하는 경우는 거의 없다. 47세 남자 환자가 정기 건강검진을 위해 복부 컴퓨터단층촬영을 시행한 결과 왼쪽 신장동에 1.2 cm 크기의 조영 증강이 되는 종괴가 발견되었다. 추가적으로 시행한 자기공명영상에서 지방 성분을 의미하는 신호 강하 소견을 보였다. 종괴는 수술 후 이소성 부신 선종으로 확인되었다.

A Rathke's cleft cyst (RCC) is a benign pituitary cyst derived from the remnant of Rathke's pouch, and usually presents as an intrasellar lesion with varying degrees of suprasellar extension. However, to date, a description of a primary prepontine RCC with no intrasellar component has not been reported. The author describes an exceptional case of a symptomatic RCC located behind the sella turcica in a 41-year-old woman who presented with severe headache. The author also provides an embryological hypothesis of the development of an ectopic RCC, with a special emphasis on radiologic characteristics.

We report rare cases of myxoid chondrosarcoma and meningomyelocele mimicking as neurogenic tumor in the posterior mediastinum. This lesions clinically mimicked neurogenic tumor due to its location and dumbbell shape appearance. The histogenesis of myxoid chondrosarcoma is discussed as skeletal origin from the thoracic vertebrae, and meningomyelocele is ectopic harmatoma lesion of C.N.S. or meningx. This lesions is concluded that distinguished for the differential diagnosis among Neurogenic tumor arising in the posterior mediastinum.

자극성 섬유종은 만성적인 자극 또는 외상에 의해 발생하는 구강 내의 흔한 섬유증식성 병소이다. 자극성 섬유종과 유사한 형태의 다른 양성 또는 악성 연조직종양의 감별진단을 위해서는 병리조직학적 검사가 필요하다. 본 증례는 엔젤만 증후군 환아에서 상악 좌측 중절치의 이소맹출로 인해 자극성 섬유종이 발생하여 미다졸람을 이용한 근육내 진정 하에 절제생검을 시행한 뒤, 병소의 재발 없이 양호한 치유 결과를 나타내고 있기에 보고하는 바이다.

Atrial fibrillation (AF) is the most common cardiac rhythm disturbance, which carries significant cardiovascular morbidity and mortality. The medical treatment for AF is cumbersome and unsatisfactory, which has highlighted the need to develop alternative treatments for AF. The recent discovery that AF is often initiated by atrial ectopic beats has resulted in treatments designed to target the ectopic sources, particularly those within the pulmonary veins. Building on the pioneering work of Cox et al., a recent reported series demonstrated the feasibility of treating patients undergoing cardiac surgery for other structural heart diseases with limited, left-atrial ablation lesion sets using alternative energy sources. As less complex modifications of the Maze procedure have been developed, a number of energy sources have been introduced to create of electrically isolating lesions within the atria. These sources have been used both endocardially in arrest heart procedures as well as epicardially in a beating heart setting. This review summarizes the recent advances in surgery for AF that will aid in the development of an effective, minimally invasive surgical procedure to cure patients with AF.

치아만곡은 조직-형태분화기에 나타나는 치아형태의 이상으로 석회화된 부위와 미석회화된 부위간의 장애로 인해서 치관 및 치근 모두에서 발생하는 기형이며, 상악 절치에서 호발하며 매복 가능성이 높다고 보고되었다. 만곡의 원인으로는 유치의 외상 치배의 이소성 발육, 낭종이 있으며 그외에 otodental syndrome, Hurler syndrome, 쇄골두개이골증에서 보고되었다. 본 증례는 치아우식증으로 인해서 발생된 치근단병소가 치아만곡을 유발할 수 있는 원인이 될 수 있다고 생각하였기에 이에 보고하는 바이다.
