Intestinal involvement and vasculopathy in von Recklinghausen's neurofibromatosis.

Involvement of the gastrointestinal system and vascular lesions are well-known features of von Recklinghausen's disease, but they are rarely detected in childhood. We report a case of von Recklinghausen's disease with intestinal involvement. The excised right hemicolectomy material of a 16-year-old girl was examined, and diffuse neurofibromatous proliferation with ganglioneuromatous features were observed. Vasculopathy was also seen in some arteries throughout the intestinal segment.
