Diagnostic Utility of PRAME Immunohistochemistry for Distinguishing Acral Melanoma From Acral Melanocytic Nevi

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Introduction Preferentially expressed antigen in melanoma (PRAME) immunohistochemistry helps distinguish non‐acral melanocytic lesions, but few studies have addressed its value in acral lesions. We aimed to identify an optimal PRAME cut‐off score to differentiate acral melanoma (AM) from acral melanocytic nevi (AMN).
