Pyoderma gangrenosum (PG) is a rare and painful skin disease with unpredictable treatment response. The lesions are recurrent and occur in areas that have suffered previous trauma. Some cases have been related to different types of surgeries and it is usually underdiagnosed and erroneously classifi ed as an infectious process. The implantation of a neurostimulation system is a surgical procedure with several possible complications, usually infectious but also non-infectious such as hypersensitivity reactions but there is no description of PG. We report a patient with a post-surgical complex regional pain syndrome in both feet that develops a necrotic, pustular, erythematous and painful lesion after the implantation of a spinal cord stimulation which was diagnosed as PG and correctly treated thanks to a multidisciplinary approach.
