Objective: Histologic diagnosis of mucosal melanoma of the head and neck can be difficult, requiring immunohistochemical stains. Our objective was to report staining characteristics of several antibodies, including a novel marker, PNL2, which has not been examined in mucosal melanoma.

Design: Pathologic specimens of primary mucosal melanomas of the head and neck were obtained, and immunohistochemical staining with 4 antibodies was performed.
