Is Perls Prussian Blue Stain for Hemosiderin a Useful Adjunct in the Diagnosis of Vasculitic Neuropathies?

Background: Perls Prussian blue stain (PPB) for hemosiderin, a marker of vascular injury is often employed as an adjunct in the diagnosis of vasculitic neuropathies. However, inflammation/vascular injury is also seen in leprosy, immune mediated, paraproteinemic, diabetic neuropathies, etc. The frequency of detection of hemosiderin in these neuropathies and its utility in diagnosis of vasculitis has not been explored.

Intraventricular Astroblastoma in an Infant: A Case Report and Review of the Literature.

Astroblastomas are rare intracranial tumours of uncertain origin and are commonly present in the supratentorial compartment. Astroblastomas often affect children and young adults. Their occurrence in an intraventricular location, in an infant, is extremely uncommon.

Lack of IDH1 mutation in astroblastomas suggests putative origin from ependymoglial cells?

Astroblastomas are extremely rare neuroepithelial tumors of uncertain histogenesis, affecting children and young adults, and constitute a new addition to the WHO 2000 classification of CNS tumors.
