[Isolated and spontaneously regressive colonic neurofibromatosis]

This case report concerns a man presenting protein losing enteropathy. Multiple polypoid colonic lesions were discovered corresponding to intra and submucosal neurofibromas. No extradigestive sign was noticed, and the diagnosis of isolated colonic neurofibromatosis was upheld. Eight years later, it was observed that both protein losing enteropathy and the colonic neurofibromas had apparently spontaneously disappeared. Isolated digestive neurofibromatosis and spontaneous tumoural regressions are discussed.
