Improving diagnostic accuracy in atypical melanocytic tumors using p16 immunohistochemistry and 9p21 fluorescence in situ hybridization: analysis of 206 second opinion cases

Abstract Diagnosing atypical melanocytic tumors can be challenging without molecular characterization, necessitating simple tools to enhance diagnostic accuracy in daily practice. This study retrospectively analyzed the utility of p16 immunohistochemistry (IHC) and 9p21 fluorescence in situ hybridiz...
