85 Abstract Objective: We intended to study the cellular proliferation by means of Ki-67 labeling index and the protein product overexpression of p53 in a series of oral intraepithelial lesions and squamous cell carcinoma, to evaluate the potential association between their histologic grades and the expression of the two markers. The expression of these markers on sections taken from hyperplast...

Trichodysplasia spinulosa (TS) is a proliferative skin disease observed in severely immunocompromized patients. It is characterized by papule and trichohyalin-rich spicule formation, epidermal acanthosis and distention of dysmorphic hair follicles overpopulated by inner root sheath cells (IRS). TS probably results from active infection with the TS-associated polyomavirus (TSPyV), as indicated b...

Background and Objective: The currentstudy aimed at investigating the histomorphological spectrum of cervical intraepithelial and invasive lesions assessing the diagnostic significance of P16/INK4a and Ki-67 in such lesions, andcorrelatingP16/INK4a and Ki-67 immunoexpression with histologic type and grade.Methods: A total of 60 cases were selectedcomprisi...

Background and Objective: Evaluation of tumor proliferative activity may provide a predicting parameter to estimate biologic aggression and a subsequent prognosis that has been evaluated in many malignancies. We have selected renal cell carcinoma (RCC) in this study. To determine tumor proliferative activity, KI67 antibody was applied and results were compared with apoptosis, applying P53 antib...

BACKGROUND The present study aimed at evaluating the expression intensities of the Mcm-2 protein and Ki-67 antigen in squamocellular carcinomas of the oral cavity and comparing their prognostic value. MATERIALS AND METHODS Forty-nine patients, operated on and treated with radiotherapy for carcinoma of the oral cavity floor and/or the mobile part of the tongue, were retrospectively analyzed. ...
