Extraordinary Case Report

Abstract: Cutaneous nerve hyperplasia is characterized by the presence of increased and hypertrophic myelinated and unmyelinated nerve fibers in the dermis. We report a case of periadnexal nerve hyperplasia as an asymptomatic and infrequent reactive histopathological change, with no associated risk of malignancy that can be seen in scars, in patients with no syndromic stigmata.
