A Case of Thalamic Anaplastic Astrocytoma with Subcutaneous Metastasis to the Scalp

Abstract

  A 12-year-old boy with a thalamic anaplastic astrocytoma underwent surgical excision of the tumor and subsequent chemoradiotherapy. Five months later, a growing mass was detected on the scalp. The mass was excised, and the histological examination revealed an astrocytoma identical to the original thalamic tumor. Subcutaneous metastasis of a brain tumor to the scalp is relatively rare. To our knowledge, this is only the second case report of subcutaneous metastasis of anaplastic astrocytoma to the scalp.
