Congenital glioblastoma multiforme: a report of three cases and a review of the literature.

The clinical histories, histologic features, and immunohistochemical staining patterns for glial fibrillary acidic protein, vimentin, p53, and epidermal growth factor receptor (EGFR) of three cases of congenital glioblastoma multiforme are given and previous case reports are reviewed. Of the three cases reported in this series, two have had long-term survivals of greater than 2 1/2 and 5 1/2 years after surgery and surgery followed by chemotherapy, respectively. Both of these cases also demonstrated p53 protein accumulation, a finding in pediatric glioblastoma multiforme associated with poor prognosis. The third case occurred in an infant who died at birth and demonstrated a well-circumscribed tumor that did not invade adjacent brain parenchyma. Considering these three cases, the biological behavior in congenital glioblastoma multiforme may not be unfavorable as portrayed in the literature or as seen in its adult counterpart.
