Pagetoid dyskeratosis is a benign incidental pathologic finding. It clinically presents as a brownish macule, and histopathologic findings show pale cells resembling cells of Paget disease within the epidermis. Pagetoid dyskeratosis of the hand can mimic a malignant melanoma and should be included in the differential diagnosis of pigmented palmar lesions that show a parallel cutaneous ridge pattern on dermoscopy.
