Malignant shwannoma is relatively rare disease in malignant soft part tumor. Recently, we have experienced two cases of malignant shwannoma. Case I, twenty seven aged man, is secondary malignant shwannoma of the right radial nerve with Von Recklinghausen disease. Case 2, forty one aged man, is primary malignant shwannoma which has come in the upper cervical region. Both cases took place in bone metastasis of the spine and finally resulted in spinal cord compression syndrome. Decompressive laminectomy and spinal fusion was done but patients have never recovered from paralysis.
