Abstract
- Malignant schwannomas in the cerebellopontine angle(CPA) are extremely rare. Two cases of malignant schwannoma in the CPA are presented. One is malignant schwannoma of the acoustic nerve and the other is malignant triton tumor(malignant schwannoma with rhabdomy-oblastic differentiation) of the acoustic nerve. No stigmata of von Recklinghausen's disease were noted in both cases. The histological, ultrastructural and immunohistochemical properties were consistent with malignant schwannoma.
