- Abstract: Pudendal neuralgia is a painful neuropathy of the pudendal nerve, which contains sensory and motor fibers that innervate the anal, perineal, and genital regions. Secondary pudendal neuralgia may occur after injuries sustained during gynecological or urological surgery; however, cases caused by tumors involving the pudendal nerve are extremely rare. Although schwannomas involving the pudendal nerve have been reported, ganglioneuromas (GN) have not. GN are uncommon tumors composed of mature ganglion cells within a Schwannian stroma and typically arise along the sympathetic plexus or in the adrenal medulla. We present the case of a 41-year-old female patient with perineal neuralgic pain caused by a GN involving the perineal branch of the pudendal nerve for 8 years. The tumor was initially diagnosed as a GN on excisional biopsy but was not completely resected and subsequently recurred. Because of its location below the inferior pubic ramus, complete resection was performed using an anterior approach. Given the potential for recurrence and the risk of malignant transformation to neuroblastoma, complete resection is essential.
