Abstract:
We describe herein a case of meningioma showing three recurrences and in the end malignant transformation. To compare the differences of MIB1, p53 and progesterone receptor expressions in benign, recurrent and malignant meningiomas of the same patient, we performed immunohistochemical stainings for those markers. MIB1 and p53 reactivities were increased in proportion to histologic aggressiveness. By contrast, the progesterone receptor expression was noted in benign meningioma but not in malignant meningioma.
