Melanocytes are neural crest derivatives. Intracranial meningeal melanocytomas (MM) are rare tumors and the available literature is sparse for these neoplasms. This review aims to provide a detailed and comprehensive literature review of these tumors. ⋯ Complete surgical resection is the ideal treatment and adjuvant radiation is to be considered for residual/recurrent tumors. Adjuvant radiotherapy may also be prescribed despite GTR, in locations with higher RR such as CP angle and Meckel cave. Because of higher-grade transformations and delayed recurrences, long-term follow-up is required.

Intramedullary spinal cord tumors (IMSCTs) are rare neoplasms and their management involves tumors resection in most cases. Regarding the surgical procedure, adequate identification of tumor boundaries is paramount to achieve an extensive tumor resection. Fluorescence image-guided surgery (FIGS) has become an increasing popular intraoperative technique used in spine neuro-oncology surgery. However, evidence is lacking of their usefulness and their safety in spinal tumors. Therefore, the aim of the present study is to give an update of the existing literature and systematically review all studies that focus on the most-used fluorophores (5 aminolevulinic acid [5-ALA], sodium fluorescein, and indocyanine green [ICG]) in IMSCTs. ⋯ In intramedullary tumor surgery, 5-ALA has shown its usefulness in identifying the tumor margins and in searching for residues because of its properties as a tumor-specific metabolic marker. Sodium fluorescein and ICG video angiography have shown promising application in ependymoma and hemangioblastomas surgery, respectively. However, the evolving role of fluorescent dyes in guiding surgical strategies in intramedullary spinal tumor has yet to be shown by randomized clinical trials.

The National Health Service faces substantial challenges with staffing in the face of administrative turbulence just after a global pandemic resulting in significant economic losses. This staffing crisis extends to neurosurgical training with pervasive problems with the balance between trainees and consultants. ⋯ Creating a sustainable neurosurgery training program to adequately fill gaps in the National Health Service will require long-term solutions and the commitment of multiple stakeholders. The first step to achieving these goals would be to maximize the available opportunities to allow trainees maximize training time to become competent day-one consultants.

Complications of Full-Endoscopic Lumbar Discectomy versus Open Lumbar Microdiscectomy: A Systematic Review and Meta-Analysis.
Endoscopic lumbar discectomy has been an alternative for treating lumbar disc herniation. Evidence-based study for the benefit zone of full-endoscopic lumbar discectomy (FELD) is necessary. The study compared the complication risks between the FELD and open discectomy or microdiscectomy. ⋯ The current evidence showed a lower risk of overall complications for FELD. The quality of evidence was moderate to low, and the risk of bias from the primary literature should be concerned.

This article aims to introduce an endoscopic-exoscopic technique for the resection of epidermoid cysts. ⋯ Endoscopic-exoscopic technique is safe and efficient in the resection of intracranial epidermoid cysts with panoramic views and superior maneuverability. With further development and accumulation of practical experiences, the endoscopic-exoscopic technique can also be applied in the resection of other intracranial tumors.
