Gastrointestinal neurofibromatosis.

Area of Science:

• Gastroenterology
• Oncology
• Genetics

Background:

• Neurofibromatosis (von Recklinghausen's disease) is a genetic disorder causing tumors to grow on nerves.
• Gastrointestinal neurogenic tumors are rare, often presenting with vague symptoms like anemia or bleeding.
• This case highlights a severe manifestation of systemic neurofibromatosis.

Observation:

• A patient with a history of neurofibromatosis presented with progressive anemia and massive upper gastrointestinal bleeding.
• Endoscopy revealed multiple gastric neurofibromas as the source of hemorrhage.
• One identified gastric tumor was a malignant schwannoma (spindle cell sarcoma).

Findings:

• The malignant schwannoma was successfully treated with endoscopic electrosurgery.
• The patient exhibited other neuroectodermal dysplasia features, including pulmonary and intracerebral schwannomas, pheochromocytoma, and ocular neurofibromas.
• This case underscores the potential for gastrointestinal bleeding from neurogenic tumors in neurofibromatosis patients.

Implications:

• Endoscopic removal is a safe and effective diagnostic and therapeutic approach for bleeding gastric or duodenal neoplasms in neurofibromatosis patients.
• Clinicians should maintain a high index of suspicion for gastrointestinal neurogenic tumors in patients with systemic neurofibromatosis presenting with bleeding.
• Early diagnosis and management are crucial for improving outcomes in rare cases of gastrointestinal neurofibromatosis complications.
