Malignant Schwannoma arising from Neuroflbromatosis (von Recklinghausen's disease): A Report of Three Cases in the Spine
Abstract
-
STUDY DESIGN: Authors experienced three cases of malignant schwannoma arising from multiple neurofibromatosis and invading the vertebrae.
OBJECTIVE
To report treatment results and preventive idea in three cases of malignant schwannoma transformed from neurofibromatosis within the retroperifoneal area and invading the vertebrae. SUMMARY OF BACKGROUND DATA: The patients with neurofibromatosis are clearly at increased risk to develop the malignant schwannoma. A review of Korean literature revealed no such cases.
RESULTS
The first case presented in the L4 body and was treated by surgical excision and chemotherapy, but she expired due to secondary metastasis in six months after diagnosis. The second case was treated by diagnostic biopsy and chemotherapy with adriamycin, ifosfamide, DTIC, mesna. He eventually lived for 14 months. After a diagnostic biopsy, the third case died due to lung metastasis before we could begin the treatment.
CONCLUSION
We recommend that neurofibromatsis patients be regularly followed-up and if necessary, CT examination of spine or abdomen should be done. If a malignant schwannoma is detected, then early treatment can be started.
