von Recklinghausen's disease and malignant changes in three patients
The Japanese Journal of Surgery
|January 1, 1982
Summary
Patients with von Recklinghausen's disease require vigilant monitoring for potential malignant transformation. Early, extensive surgical removal is crucial when malignancy is suspected to improve outcomes.
Area of Science:
- Oncology
- Genetics
- Dermatology
Background:
- Von Recklinghausen's disease, also known as neurofibromatosis type 1 (NF1), is a genetic disorder.
- Malignant peripheral nerve sheath tumors (MPNSTs) are rare but serious complications of NF1.
Observation:
- This study reports on three Japanese patients with NF1 who developed malignant changes.
- Primary malignant lesions were located in the chest wall, buttock, and neck.
- Local recurrences and distant metastases were observed in two patients post-surgery.
Findings:
- One patient died 21 months after malignancy diagnosis.
- Multidisciplinary treatment showed some efficacy in managing local recurrences and pulmonary metastases in one case.
- Pulmonary metastases were present at admission in another patient, who died 8 months post-diagnosis.
Implications:
- Close follow-up is essential for NF1 patients due to the risk of malignant transformation.
- Prompt and complete surgical excision (en-bloc resection) is recommended upon suspicion of malignancy.
- Further research into optimal management strategies for MPNSTs in NF1 patients is warranted.
