 A 45-year-old woman with von Recklinghausen neurofibromatosis developed a malignant Schwannoma with two neurofibromas of the duodenum, and small elevated lesions (hyperplasia of the peripheral nerve) of the small intestine and colon.

 Although gastrointestinal neurogenic tumor has been known to occur frequently in patients with von Recklinghausen neurofibromatosis, such a case as described here has not yet been reported. Results of clinical investigation in this case were reported as well as radiological, endoscopic and pathological features of the lesions in detail.
