Utility of cytokeratin 20 and Ki-67 as markers of urothelial dysplasia.
Reactive urothelial atypia (RUA) can be difficult to differentiate from dysplastic urothelium. The goal was to evaluate the efficacy of cytokeratin 20 (CK20), Ki-67 and E-cadherin (E-Cad) in this regard. Fifty carcinoma in situ (CIS) cases, 50 non-neoplastic urothelia (25 normal, 25 reactive urothelial atypia (RUA)) and 17 atypia of unknown significance (AUS) cases were evaluated. All cases wer...
متن کاملDifferential diagnosis of urothelial carcinoma in situ from non-neoplastic urothelia: Analysis of CK20, CD44, P53 and Ki67
Background: Flat urothelial lesions comprise a spectrum of morphologic changes ranging from reactive atypia to carcinoma in situ (CIS). Urothelial dysplasia and CIS are associated with the recurrence and progression of urothelial carcinoma. Distinguishing CIS and dysplasia from reactive atypia based on histolopathogical features alone is often difficult. Using different immunohistochemical mark...

background: materials and methods: this was a cross-sectional study carried out among 70 samples, including 10 samples from normal healthy mucosa categorized into group 1, group 2 (30 olp), and group 3 (30 oed) samples. five sections (4 μm thick) were obtained and stained with monoclonal antibodies such as ki-67, p53, bcl-2, and bax and analyzed for number of positive cells and also for inten...
متن کاملDiagnostic utility of p53 and CK20 immunohistochemical expression grading urothelial malignancies
INTRODUCTION Current grading system in application by WHO/ISUP divides urothelial malignancies in low and high grade by morphologic criteria while strict segregation may become cumbersome in limited tissue specimens. As grading these carcinomas are of utmost prognostic significance after depth of invasion, therefore we evaluated the role of immunohistochemical expression of p53 and cytokeratin ...
متن کاملimmunohistochemical expression of p53 and ki-67 in different histopathological variants of basal cell carcinoma
background : basal cell carcinoma is the most common form of skin cancer in men. increased marker expressions of apoptosis and cell proliferation have been found in the majority of basal cell carcinomas. our purpose was to determine whether any correlation between immunohistochemical expressions of p53 and ki-67 in different histopathological variants of basal cell carcinoma and patient’s age, ...
