Abstract

Pleomorphic xanthoastrocytomas are indolent, astrocytic tumors usually located in the superficial cerebral cortex. They have not been described as occurring in the pineal region. We describe a patient with an astrocytic tumor arising in the pineal region that fulfilled all of the morphologic and immunohistochemical criteria of a pleomorphic xanthoastrocytoma. To our knowledge, this is the first description of a pleomorphic xanthoastrocytoma located in the pineal region.

摘要

多形性黄色星形细胞瘤是一种惰性的星形细胞瘤，通常位于大脑皮层表面。它们尚未被描述为发生在松果体区域。我们描述了一例发生在松果体区域的星形细胞瘤患者，其形态学和免疫组织化学特征均符合多形性黄色星形细胞瘤的标准。据我们所知，这是首例位于松果体区域的多形性黄色星形细胞瘤的描述。
