Phlebectasia is an abnormal dilatation of an isolated vein and a rare venous anomaly and is usually asymptomatic. Clinically internal jugular phlebectasia is a self limited benign condition and usually no treatment is required after initial diagnosis. So suspection of this disease and appropriate diagnostic approaches are essential to avoid unnecessary surgical intervention. We present three cases of internal jugular phlebectasia of which diagnosis was made by neck sonography and CT.

Keratoconjunctivitis sicca (KCS) is a relatively common eye disease in the dog, Reduction or arrest of aqueous tear production by lacrimal glands results in quantitative alteration of the precorneal tear film (PTF) and KCS may result. A dog with a presumptive diagnosis of KCS referred was used for the study of KCS. Cytological and histopathologic examination is performed, and the various types of medical and surgical treatment are studied, including the operation of parotid duct transposition (PDT). This report described unilateral KCS in a dog of unknown etiology who responded to PDT.

Cerebral fat embolism (CFE) is a rare, albeit potentially lethal complication of long-bone fractures. All trauma patients who are initially lucid and subsequently experience mental status deterioration should undergo immediate evaluation of possible CFE. In the present case, magnetic resonance imaging (MRI) was the most sensitive technique for the diagnosis of CFE, particularly the use of diffusionweighted images (DWI). The authors present this case to report a pathophysiologybased interpretation of the MR characteristics and treatment of CFE.

Immunoglobulin G4 (IgG4) related disease (IgG4-RD) is currently considered an immune-mediated condition and is recognized as a disorder group with common pathological, hematological, and clinical characteristics. This disease may involve diverse organs of the head and neck, and include mainly the lacrimal gland, orbit, thyroid gland, pituitary gland, and the meninges. Here, we report a case of IgG4-RD in a 65-year-old female showing head- and neck-limited but synchronously and mainly manifesting as otalgia and facial neuritis.

Angiosarcoma of the breast is a rare malignant sarcoma of endovascular origin that presents with various radiological findings. We encountered a case of angiosarcoma of the breast presenting as an irregular indistinct hyperechoic mass on ultrasonography, with a large single angiosarcoma of the spleen in a previously healthy 36-year-old female. Herein, we report the imaging and pathologic findings and review the literature.

Purpose: Recently, a wide application of gastrofiberscopy in the pediatric group have revealed that nodular duodenitis is not an uncommon disease in children and is suspected to be associated with H. pylori infection. The aim of this retrospective study was to investigate the clinical and histopathologic features in children with nodular duodenitis, and to assess the correlations beween both. Methods: During a period of 5 years (Jan. 1995~Dec. 1999), we investigated clinical, endoscopic and histopathologic features of 39 consecutive patients diagnosed as having nodular duodenitis at Pediatric department of Seoul Red Cross Hospital. In 35 children with nodular duodenitis endoscopic biopsy specimens were stained with Hematoxylin & Eosin and Giemsa's stain, and were graded according to the criteria outlined by Triadafilopoulos, Whitehead et al., and Prieto et al.. Statistical analyses were performed with Graph PAD InStat. Results: The prevalence rate of nodular duodenitis was 17.1% and the most frequent chief complaint was abdominal pain (69.2%). Endoscopically grade 1 was the most common (45.7%) and nodular gastritis was coexistent in 28.3%. The most common histology of the duodenum was grade 2 (54.3%), and the most common histologic score of the stomach was 2 (42.9%). H. pylori was found in the duodenum in 37.1%, and in the stomach in 31.4%. The correlation coefficient between the endoscopic grade and the histologic grade of nodular duodenitis was 0.3983 (p=0.0178). And the correlation coefficient between the histologic grade and the grade of H. pylori colonization in the duodenum was 0.5154 (p=0.0018). Conclusion: There was significant correlation between the endoscopic grade and the histologic grade of nodular duodenitis, and was also significant correlation between the histologic grade and the grade of H. pylori colonization in the duodenum. Therfore H. pylori infection should be regarded as an etiologic factor of nodular duodenitis.

본 논문에서는 폐암의 변이 형태 분석을 위한 정량적 분석 방법을 연구하였다. 보다 객관적인 분석의 필수적 요인인 정확한 분할을 이해 질감 특징과 통계학적 분류방법을 이용하였으며, 변이 형태 분석을 위해서 분할된 ROI 로부터 여러 가지 형태학적 특성값과 질감 특성값을 추출하여 변이 형태에 따라 비교분석하였다. 이러한 폐암의 변이 형태 분석을 위한 방법은 다른 기관으로의 원격전이가 쉬운 종양의 특성평가에 대한 객관적 병리진단의 보조도구로 사용될 수 있을 것이다.

A rare small cell carcinoma of the trachea was managed in a 59 year old female patient. The diagnosis was confirmed by histopathological and immunohistochemical studies. Surgical resection and adjuvant chemotherapy were done. The patient died 6 months later due to multiple metastasis.

In 1977, Robinson & Martinez described a distinct varient of ameloblastomas in which the response to curettage was found to be favorable, with a recurrence rate of 25%. They referred to this varient as unicystic ameloblastoma. Unicystic ameloblastoma occur most commonly in the second and third decades of life, which is considerablly younger than the average age of discovery for the classical ameloblastoma. For the accurate histopathological diagnosis of the unicystic ameloblastoma, the specimen obtained the excisional biopsy, complete enucleation or incisional biopsy from the multiple site of the lesion. The purpose of this report is to review of the literature and to present three cases in which an unicystic ameloblastoma appear to be arising in the wall of a dentigerous cyst.

치성종양은 악구강계 영역의 질환 중 중요한 관심거리가 되어왔으며, 이중 상피성 치성종양에 관한 보고는 많으나, 중배엽성 치성종양에 관한 보고는 많이 이루어지지 않았다. 저자는 1975년부터 1985년까지 서울대학교병원 치과진료부에서 방사선학적, 병리학적으로 중배엽성 치성종양인 치성섬유종, 치성점액종, 백악질형성섬유종으로 진단된 증례들을 토대로 하여 연구, 분석한 결과 다음과 같은 결과를 얻었다. 1. 치성섬유종의 연령분포는 32세에서 72세로 광범위 하였으며, 발생위치는 모두 상악구치부이었고, 단방성이 2증례, 다방성이 1증례이었다. 2. 치성점액종의 연령분포는 40세에서 55세로 비교적 중년층에서 호발했고, 4증례가 상악에, 2증례가 하악에 발생하였다. 6증례 모두 방사선학적으로 다방성 방사선투과성을 보였으며, 경계는 비교적 불분명하였다. 3. 백악질형성섬유종은 주로 ?년에서 중년 성인 사이에 많이 발행하였고 40대에 가장 많은 출현율을 보였다. 남녀비는 약 1:2로 여자에게서 빈발하였다. 19증례중 하악에 15증례, 상악에 4증례가 발생하여, 하악이 호발부위였으며, 상하악 소구치, 대구치 부위에 발생하였다. 방사선학적으로 방사선투과성이 2증례, 혼합성이 12증례, 방사선불투과성이 5증례이었다.
