배뇨곤란, 혈뇨 및 간헐적인 구토를 보이는 8살의 중성화된 수컷 슈나우져가 병원에 내원하였다. 투시기 하에서 양성 요도 조영을 실시 하였고, 전립선 주위 요도에서 조영제가 누출 되는 것을 확인 하였다. 또한 전립선 요도부터 방광 삼각까지의 충만 결손이 관찰 되었다. 수술적인 교정이 부분적인 방광 폐쇄로 인해 실시 되었고 수술 중 주변 장기로 전이 소견이 확인되어 안락사를 실시 하였다. 주변 조직의 전이를 확인 하고 위하여 Cytokeratins (AE1/AE3) 를 이용하여, 주위 림프 조직을 염색하여, 전립선의 상피 세포 유래의 세포가 림프절에 전이 되었음을 확인 하였다. 본 증례는 수컷 개의 전립선 선암종의 발생 증례로 임상 소견, 영상 진단, 조직 병리학적인 자료를 기술 하였다.

Chordoma is relatively uncommon tumor comprising $1\sim4%$ of primary malignant bone tumors, and believed to arise from the remnants of notochordal tissue. Because of its rare occurrence in the thoracic spine, we report a case of chordoma involving the thoracic spine. A 45-year-old male was sufferred from chest pain radiating to the back. Chest CT showed a well marginated, round huge mass with multiseptated enhancement at the thoracic spine from T5 to T8 level. After percutaneous needle aspiration, piecemeal resection of the tumor was done. On cytologic smears, two types of neoplastic cells were arranged in sheets and cords in mucinous background. One type of cells consisted of medium sized cells with pink cytoplasm and round nuclei. The other type had voluminous bubbly or clear cytoplasm divided by intracytoplasmic septae imparting a feathery or basket-like appearance. Histologically, the tumor showed lobulated feature divided by fibrous septae and the tumor cells were pink eosinophilic or physaliphorous in morphology. Immunohistochemically, the tumor cells revealed strong positivity for low(AE1) and high (AE3) molecular weight cytokeratins.

Ameloblastoma is the most common odontogenic tumor of the jawbones, but the origin of this tumor has been remained to be unproven. Cytokeratins (CKs) are specific intermediate filament of epithelial cells, and vimentin is expressed in mesenchymal cells. The immunohistochemical detection of different CKs and vimentin has made it easier to know the origin of tumor. Paraffin-embedded tissue sections from 15 ameloblastomas and 1 ameloblastic carcinoma were used for immunohistochemical evaluation of CK 7, 8, 13, 14, 19 and vimentin. Their expression is evaluated in different tumor cells, which are observed in different type of tumors. In the follicular and reticular subtype, central stellate cells of tumor nests expressed CK 8, 14, 19 and peripheral columnar cells expressed CK 14. CK 7, and 13 were not expressed. Vimentin was detected in fibrous stroma around tumor nest, not in tumor cells. The tumor cells of ameloblastic carcinoma expressed CK 7, 14 and 19, but CK 8 was more weakly stained than that in ameloblastoma. Central stellate cells and peripheral columnar cells of acanthomatous subtype showed same expression pattern with others. Meta plastic squamous cells expressed CK 8, 14, 19 and keratinizing squamous cells expressed CK 13, 19. CK 7 and vimentin were not detected in tumor cells and vimentin was expressed in fibrous stroma. Most of the tumor cells of ameloblastoma showed CK 14 and CK 19 and did not express CK 7 and vimentin. These findings were similar to the immunophenotype of dental lamina. And these results will be beneficial to differential diagnosis of odontogenic tumors and other kind of tumors arising at the oral cavity.

Purpose: As UBC IRMA is being tested, patients out of the reference value are reacting within the value again a few days later the urine collection tested, which causes the reliability of the test to decrease as a result. In this study, we can assume that the physiological changes in the factors would affect the results. The purpose of the study is to find out whether hematuria and proteinuria in the sample as well as the interval time (3 hours or more recommended) have affected the results. As a result, we could discover the changes in factors and increase the reliability of the test. Materials and Methods: 468 people (female: 249, male: 219) who came for the check-up were presented herein for medical examination from 2013.3.15 to 2013.1.2. Some people out of 468 who have reacted onto the reference value were divided into group low titer zone, ow-middle titer zone, and middle-high titer zone and tested for hematuria and proteinuria. During that period, 48 outpatients were asked to fill in a questionnaire regarding the urination interval time. The reagents used were (IDL Biotech AB, Sweden) and UBC IRMA. Results: Of the patients that are formed in the reference value of ($0.1-34.0{\mu}g/L$) turn out to be 52.7 years average age in their low concentration, ($mean{\pm}SD$) of the value of $0.10{\pm}0.02{\mu}g/L$. Among 80 people (50.8%, female: 49.2%), 16 patients (20%) have shown reaction to microscopic hematuria and 10 patients (12.5%) responded to proteinuria. In the average low concentration under 52.5 years of average age, 43 people (53%) have shown reaction to microscopic hematuria and 21 people (26.3%) are proteinuric patients out of 80 patients (male: 50.8%, female: 51.3%). In the middle high concentration of $11.8{\pm}4.82{\mu}g/L$ under the average age 51.7 years, 35 patients (53%) have responded to the microscopic hematuria and proteinuric patients are 26 people (39.3%) out of 66 people (men: 44%, women: 56%). In addition, in the concentration of $51.7{\pm}43.5{\mu}g/L$, some patients who get out of the reference value are observed as the average age of 52.0. 11 patients (78.6%) out of 14 (male: 35.7%, female: 64.3%) react to the microscopic hematuria. There show 6 people (42.8%) who turn out to be as proteinuric patients. As for the interval time, $1.67{\pm}3.71{\mu}g/L$ was the average value among 48 patients (female: 45.8%, male: 54.2%). Conclusion: We cannot see if proteinuria and hematuria directly affect abnormal results of inspection of 8,18 cytokeratin; however, we can find out that they statistically have an influence on highly generating UBC among several mechanisms. Also, although urination interval time was various every 15 minutes, we it does not affect these results.
