“…7 In cases with basaloid epithelial component (basal cell carcinosarcomas), markers such as BerEP4 and Bcl-2 have also shown positivity. 16 In addition, p53 has been reported to be overexpressed by both epithelial and mesenchymal components. 16 However, the case series by Kwak et al,11 showed such co-expression in only two of the 11 cases, with no expression in either component in one case, while four cases each had p53 expression in either the epithelial or mesenchymal component.The mesenchymal component may express vimentin, actin, CD10, CD34, and CD68, depending on its differentiation.…”
