Comparative immunohistochemical analysis of aurora-A and aurora-B expression in human glioblastomas. Associations with proliferative activity and clinicopathological features.

In the present study, we carried out a comparative immunohistochemical analysis of aurora-A and aurora-B expression in 40 patients with primary glioblastomas, and attempted to identify any associations with Ki-67 index and the patients' clinical features. The impact of various treatment modalities and proliferative activity on patient outcome was also assessed. Immunohistochemistry was carried out using formalin-fixed and paraffin-embedded tissue sections.

Simultaneous occurrence of cerebellar medulloblastoma and pituitary adenoma: A case report.

Purpose: We present the unusual occurrence of two distinct neoplasms in a 42-year-old woman with an operated pituitary adenoma 18 years ago.

Methods: Clinical history, magnetic resonance imaging studies and histopathological findings were utilized for our diagnostic considerations.

Results: Concomitant presence of a cerebellar medulloblastoma secondary disseminated within the spinal canal and a pituitary macroadenoma, was identified.
