متن کاملAn overview of Bcl-2 expression in histopathological variants of basal cell carcinoma, squamous cell carcinoma, actinic keratosis and seborrheic keratosis.
The Bcl-2 protein has been shown to suppress cell death and protects cell against apoptosis induced by different death-inducing signals. In this study the authors have analyzed imunohistochemically the expression of Bcl-2 protein in the histopathological variants of the most common malignant tumors of the skin--basal cell carcinoma (BCC) and squamous cell tumor (SCC), as well as in the precance...

متن کاملANGIOGENESIS ASSESSMENT IN BASAL CELL CARCINOMA
Basal cell carcinoma (BCC) is currently the most common cutaneous cancer found in humans. Although it generally shows a relatively benign course (BCCl), some cases show aggressive behavior (BCC2).
