Neurofibromas, which arise from perineural and Schwann cells, commonly occur throughout the body, but they rarely have been reported to originate from the spermatic cord. The solitary neurofibroma is a localized tumour that, by definition, occurs in patients who do not have von Recklinghausen's disease. Its exact incidence is unknown because of the difficulty in excluding von Recklinghausen's disease in some cases. Leiomyomas, lipomas, fibromas, haemangiomas, and epidermoid cysts have been described as benign tumours of the scrotum, but rarely has an extratesticular solitary neurofibroma of the spermatic cord been reported. We report a case of a solitary neurofibroma arising from the left spermatic cord. No signs of von Recklinghausen's disease were identified.
