    Abstract

    Blue nail dyschromia may represent melanocytic, vascular, or other etiologies. A case of a subungual blue nodule is presented, with a pseudo-clubbed nail. On histopathologic examination, there was a combined subungual blue nevus, with features of a common blue nevus and a pigmented epithelioid melanocytoma. This unusual presentation is reviewed, with a discussion of blue nail dyschromia and subungual blue nevi.
