intervention of primary focus of type 1 neurofibromatosis presenting with melena and gastric hemorrhage of unknown origin and nursing care: a case report

There are four types of neurofibromatosis, with types 1 and 2 being the most prevalent among them. the disease incidence is 1 in every 3,000 births.  in the present study, we reported a patient with neurofibromatosis type 1 presenting with melanoma and gastric hemorrhage of unknown origin. a 37-year-old woman with a history of gastrointestinal bleeding and evidence of multiple retroperitoneal masses in the computed tomography scans of abdominal and pelvic cavities was admitted to our hospital. the masses were successfully removed by surgery.in cases of bleeding with an unknown cause, especially in patients with neurofibromatosis, the possibility of small intestinal tumors, especially gastrointestinal stromal tumors, should be considered.
