Cytopathological findings of granular cell glioblastoma in intraoperative squash smear preparations: A case report.

This article presents a case report on the cytopathological findings of granular cell glioblastoma (GCBG) in intraoperative squash smear preparations. GCBG is a rare and aggressive type of brain tumor that is difficult to diagnose. The article describes the microscopic features of GCBG, including the presence of large macrophage-like tumor cells with eosinophilic granular cytoplasm and distinct nucleoli. The authors emphasize the importance of caution in diagnosing GCBG and suggest communicating potential differential diagnoses to neurosurgeons. [Extracted from the article]
