Circumscribed Meningeal Melanocytic Neoplasms: CNS WHO Grade, Molecular Profile, and Clinical Outcomes

Brain Pathology, EarlyView.
In this study including 31 circumscribed meningeal melanocytic neoplasms (melanocytoma, intermediate‐grade melanocytic tumor [IMT], and melanoma), overall survival (OS) differed significantly among the groups, with melanoma showing significantly worse OS than melanocytoma and IMT showing intermediate OS between melanocytoma and melanoma.

Rare lesions of the cerebellopontine angle [PDF]

Turkish Neurosurgery, 2009
Vestibular schwannomas, meningiomas and epidermoids account for a vast majority of the lesions occurring in the cerebellopontine angle (CPA). Neoplastic and non-neoplastic pathologies other than these tumors constitute 1% of all lesions located in the CPA.

A Phase Ib Case Series Using Bortezomib With Chemotherapy in Atypical Teratoid/Rhabdoid Tumors

Cancer Medicine, Volume 15, Issue 9, September 2026.
ABSTRACT Background Atypical teratoid/rhabdoid tumors (ATRTs) are aggressive pediatric brain tumors that are sensitive to proteasome inhibitors in preclinical models. We evaluated the feasibility of combining the proteasome inhibitor, bortezomib, with chemotherapy.
