경부기도의 종양은 편평상피암과 함께 이비인후과의에게 있어서 호흡곤란 환자의 감별진단을 위해 매우 중요한 임상적 의미를 갖는다. 종양은 암종에 의한 사망률의 0.1%이하를 차지하는 드문 질환이며 선양낭성암종은 기도의 원발성 종양중 두 번째로 많은 질환이다. 갑상선종양의 기도의 직접적인 침범이 흔히 발견되는 상태이며, 그다음으로 편평상피암, 선양낭성암종이 기도의 원발성 종양으로 흔한 질환이다. 갑상선의 악성종양이 기도의 벽이나 내강을 침입하는 것과 마찬가지로, 기도의 원발성 악성종양도 흔히 갑상선을 침범하여 갑상선의 종괴처럼 발현할 수 있다. 본 연구는 이와 같이 갑상선의 악성종양과 유사한 임상경과를 보이는 기도의 선양낭성암종의 향후 감별진단을 위해 4명의 조직학적으로 증명된 갑상선을 침범하는 기도의 선양낭성암종환자의 임상기록과 전산화 단층촬영소견을 후향적으로 관찰하였다. 전산화 단층촬영에서 이들은 기도에 넓은 기저부를 가지고 갑상선을 밀고있는 균일한 음영의 일반적으로 부드러운 경계를 가지는 종괴로 보였으며, 횡단면과 두정면에서 모두 기도 벽의 비후소견을 보였다. 이러한 소견은 기도의 원발성 선양낭성암종의 감별에 도움이 될 것으로 생각된다.

There are various diseases in soft tissue tumors that occur in subcutaneous tissue, and hematoma generally would be occurred in traumatic or coagulopathic condition. We report a case of hematoma on left gluteal area that was diagnosed by ultrasonography and was resected in 70 year old woman who visited the hospital because of left gluteal mass detected by chance two month ago and slowly growing.

Computerized Tomography is now well established and important noninvasive method of diagnosting mediastinal mass lesions because of its superior imaging of their size, location and internal composition. Authors ana lysed and present CT findings of 30 surgically proven mediastinal tumors and cysts that were studied and treated at the Yeungnam University Hospital during recent 6 years. The most common tumor was thymona(9 cases), and teratoma(6 cases), lymphoma(6 cases), bronchogenic cyst(4 cases), neurogenic tumor (4 cases), pericardial cyst(1 case) were next in order of frequency. There were 5 cases of thymoma showing homogenous solid density mass, 2 cases were malignant thymoma and myasthenia gravis was present in 2 cases. A case of thymolipoma and a case of thymic carcinoma were included. All teratomas were cystic masses but pathognomic fat, and calcified density were seen only in 4 cases. 5 cases were located in anterior mediastinum and 1 case was in posterior mediastinum. Lymphoma(3 Hodgkin's and 3 non-Hodgkin's) appeared as irregular lobulated mass in anterior mediastinum. Neurogenic tumor(2 ganglioneuroma and 2 neurilemmoma) appeared as homogenous density mass located in posterior mediastinum. Among the 4 bronchogenic cysts, 2 were located in retrotracheal area, 1 was located in subcarinal and 1 was in parathoracic area. One case of pericardial cyst was oval shaped cystic mass located in left pericardiac border.

A rare case of telangiectatic osteosarcoma of the sphenoid bone was reported. The patient was a 27-year-old male and had suffered from left eye protrusion and diplopia for three months. Radiologically, a lobulated osteolytic lesion was located between sphenoid and left temporal bone. Pathologically, the tumor had multiloculated blood filled cystic vascular spaces and osteoid formation by malignant spindle osteoblast cells. The differential diagnosis of this rare entity from aneurysmal bone cyst was important radiologically and pathologically. This case is the second case of telangiectatic osteosarcoma of the sphenoid bone followed by a case of Whitehead RE and Melhem ER in 1998.

10살된 암컷 진도개에서 7.0$\times$7.0$\times$2.5 cm 와 5.0$\times$4.0$\times$2.0 cm 크기의 종괴가 왼쪽 어깨와 흉부의 아래부위 피하에서 각각 관찰되었다. 육안적으로 종괴는 주위 조직과 잘 구분되어 있었고 절단면에서는 회농성 삼출물이 관찰되었다. 병리 조직학적 소견 상 모낭 유래의 낭성 구조물들이 특정이었는데 이들의 벽은 모낭을 이루는 세 가지 부분인 누두부(infundibular), 협부(isthmus), 아래구역(inferior segment)과 유사하게 분화된 세포들로 구성되어 있었다.

병변의 양상에 따른 감별진단 재발성 이하선 종대를 보이는 경우 타액선조영술이 영상진단방법중 1차적인 선택이 된다. Stensen 씨관이나 중심선관(central glandular duct)의 확장을 보이는 경우 만성 타액선염으로 진단할 수 있다. 소아에서의 단일성 양성종괴의 감별진단은 임파절, 혈관종, 양성혼합종양, 저급점액상피암, 임파관종 등이다. 성인에서의 단일성, 양성으로 관찰되는 종괴는 양성혼합종양, Warthin씨 종양, 저급점액상피암, 선상낭성암, 소포상세포암 등이다. 여러개의 종괴를 보이는 경우 Warthin씨 종양, 소포상세포암, 임파종, 육아종, 전이암 등이며 단일성 낭성종괴의 경우는 branchial cleft cyst,, Warthin씨 종양, 상피낭포 등이다.

성선 외 생식세포종양은 비교적 드물어 모든 생식세포종양의 5% 미만을 차지한다. 주로 천미부생식세포종양이 골반부나 후복막으로 확장된 경우가 대부분이며, 후복막이나 복강 내에 발생하는 생식세포종양은 매우 드물다. 저자는 복부 종괴를 주소로 내원한 18개월 된 여아에서 간 전이를 동반한 복강 내 혼합 생식세포종양을 치료하였다. 복부 초음파 및 전산화 단층촬영에서 복부 좌상사분역에 석회화, 고형 및 지방 성분을 포함하고 있는 낭성 종괴와 간에 1cm 크기의 결절이 관찰되었다. 종괴는 개복 후 제거되었으며, 병리조직학적으로 대부분의 내배엽동 종양과 적은 성숙 기형종으로 구성된 혼합 생식세포종양으로 진단되었으며, 간의 전이병변도 동일하게 진단되었다. 수술 후 항암화학요법을 시행하였으며, 환자는 현재 수술 후 10년이 경과하였으나 재발의 소견은 없다.

Renal angiomyolipomas (AMLs) are typically solid tumors, but there have been few reports of a rare cystic variant of AML. AML with epithelial cysts, where the epithelial cyst has a cuboidal epithelial lining, account for the majority of them. Next, epithelioid AML (EAML) with cystic changes due to hemorrhage and necrosis, which is composed of epithelioid cells with abundant eosinophilic cytoplasm, have also been reported. These rare cystic types of AML can be mistaken for other cystic tumors, such as cystic renal cell carcinoma, in preoperative imaging. We report the imaging findings of a rare case of EAML with epithelial cysts.

A 10-year-old spayed female Pekinese dog was referred to veterinary medical teaching hospital of Chonbuk National University with signs of dysuria, abdominal distension, and hematuria. Abdominal radiography revealed a large oval soft tissue mass in cranial abdomen, which was a fluid filled cyst containing a round mass by ultrasonography. Exploratory laparatomy found a 4 cm cyst containing reddish brown fluid and a 1.5 cm small round mass attached to the wall. Cytological impression of the imprint smears of the resected mass were highly malignant adenocarcinoma, which was confirmed by histopathology of the mass and the cyst. After the surgery the patient recovered uneventfully and discharged. The tumor recurred about one year after surgery, and second surgery performed at the owner's request. However the tumor recurred in two months with metastatic disease in the lung and the dog survived three more months after surgery.

Gastric teratoma is an extremely rare neoplasm in children which account for less than one percent of all teratomas. Unlike other teratomas, most reported gastric teratomas was benign except one case and occurred predominantly in boys. Additionally, gastric teratomas present in the first year of life as a palpable mass, abdominal distension, vomiting, hematemesis or respiratory distress. Patients with gastric teratomas have an excellent prognosis after complete excision of the tumor. We report a case of immature gastric teratoma in an one-day-old boy, which was diagnosed by abdominal sonography and CT scan, and confirmed by surgery.
