Penile Traumatic Neuroma: A Late Complication of Penile Dorsal Neurotomy to Treat Premature Ejaculation

IntroductionTraumatic neuroma is a reactive process caused by the regeneration of an injured nerve that usually forms a nodular proliferation of small nerve bundles. Penile traumatic neuroma is rare; only a few cases related to circumcision have been reported.AimTo report on a case of traumatic neuroma in the penis after selective dorsal neurotomy (SDN) to treat premature ejaculation.MethodsThe penile traumatic neuroma was successfully removed by excision and confirmed by histopathology.ResultsA 55-year-old man who had had several painless, slow-growing nodules on his penis for 2 years presented to our hospital. He had no history of genital trauma, urinary tract infection, or penile surgery, except SDN to treat premature ejaculation. The nodules were excised and the final diagnosis was traumatic neuroma. No recurrence has been detected during 1 year of follow-up.ConclusionThe main complications of SDN are recurrence of premature ejaculation, pain or paresthesia on the glans penis, and erectile dysfunction. However, no traumatic neuroma has been reported as a complication. We report that a traumatic neuroma can occur after SDN.
