Ovarian neurofibroma: a rare visceral occurrence of type 1 neurofibromatosis and an unusual cause of chronic pelvic pain.

Neurofibromatosis type 1 is a dominantly inherited neurologic disorder that affects primarily the skin, bones, and peripheral nervous system. The disorder may be associated with a variety of clinical manifestations including both superficial and deep-seated lesions such as café-au-lait spots, skinfold freckling, Lisch nodules, and cutaneous, deeper, and visceral neurofibromas, Visceral involvement, in particular, rarely affects the genital tract, and isolated ovarian neurofibromas are extremely rare. Herein is reported a case of a solitary neurofibroma of the left ovary in a 24-year-old woman with chronic pelvic pain. The tumor was excised at laparoscopy, with complete resolution of symptoms. After 3 years of follow-up, the patient remains asymptomatic and free of any further visceral involvement.
