Immunohistochemical expression of endothelial cell markers in case of Dieulafoy lesion: Is there is a differences?
نویسندگان
چکیده
Dieulafoy's lesion (DL) is a rare of cases of acute upper GIT bleeding. We investigate the immunohistochemical expression of several endothelial markers in a patient with Dieulafoy’s lesion of the stomach, by comparing the results with data on the expression of these markers in other types of gastric pathology. The histological examination of the patient with Dieulafoy’s lesion showed small erosive defect covered with fibrin, under which there were several highly deformed and dilated blood vessels with different diameters. We found that the expression of EC markers CD31, CD34, vWF and VEGF in gastric blood vessels of DL is heterogeneous and there is some differences compared with endothelial markers expression in other gastric pathology.

Background and Aims: P504S (AMACR) is a mitochondrial enzyme expressed in renal cell carcinoma. Some of immunohistochemical markers in renal cell tumors are independent prognostic factor and show relation with histologic grading. AMACR expression increases with higher histological grading in different tumors; however, in RCC it is not obvious. In this study, we tried to investigate if ...

Background and Aim: It has been suggested that oral lichen planus (OLP) can be a potential premalignant lesion. Reports are also available on the role of bcl-2 and p53 proteins in malignant transformation of OLP into oral squamous cell carcinoma (OSCC). Due to controversies in these reports, the present study aimed to compare the expression of p53 and bcl-2 markers in OLP and OSCC. Materials a...
