Association of GIST, breast cancer and schwannoma in a 60-year-old woman affected by type-1 von Recklinghausen's neurofibromatosis.

Neurofibromatosis (NF1 or von Recklinghausen's disease) is a common autosomal dominant disease associated with a higher incidence of neoplasms than in the general population. We report the case of a 60-year-old woman affected by NF1 who was coincidentally diagnosed with a gastrointestinal stromal tumor, a breast carcinoma and a peripheral nervous system tumor.
