Autonomic denervation dermatitis is a newly introduced term that describes an occurrence of scaly eczematous lesion at the site of incision of a previous surgery. The time lag between the incision and the occurrence of the eczematous lesion varies greatly, ranging from months to years. Autonomic denervation dermatitis by definition can occur at any site of previous surgery, however, few sites are specially named, like Surgery of the knee, injury to the infrapatellar branch of the saphenous nerve, traumatic eczematous dermatitis (SKINTED) occurring after total knee arthroplasty. Autonomic denervation dermatitis is believed to occur due to transection of dermal nerves which pathophysiologically differentiates it from post-traumatic eczema which is an inflammatory reaction presenting as an eczematous lesions developing at and around sites of mechanical, thermal, or chemical injury. Herein, I will describe a series of five such cases and try to differentiate between autonomic denervation dermatitis and post-traumatic eczema.
