Scalp Metastasis from Glioblastoma Multiforme: A Case Report and Literature Review

Abstract

Glioblastoma multiforme (GBM) is a common malignant brain tumor that rarely metastasizes extracranially, despite its aggressive clinical course. This report details the case of a young man presenting with a single subcutaneous localization of GBM that arose six months after initial surgery and recurred after excision. Only six other cases of scalp metastasis of GBM following surgery have been described in the literature, each with peculiar features. Whenever feasible, surgery is the most effective way to obtain local control of disease. However, a correct approach must be carefully planned to minimize the risks of recurrence and wound dehiscence.
