Spinal cord stimulation has been used since the 1960s to treat chronic consistent refractory pain such as failed back surgery syndrome and complex regional pain syndrome. The purpose of this paper is to describe a rare case of cutaneous reaction to spinal cord stimulator device component. A 42-year-old man diagnosed of complex regional pain syndrome affecting the right upper extremity underwent implantation of spinal cord stimulator device. The patient developed erythematous plaque and pruritis on right flank area on postoperative day 21. The erythematous rash was localized along the lead, and the anchoring site and the implantable pulse generator site were not involved. Dexamethasone was intravenously administered, and topical steroid was applied. Dexamethasone was changed to oral steroid and was stopped after tapering for 14 days. Some cases of allergic reaction of spinal cord stimulator devices could be controlled by medical treatment like corticosteroid.
