The XXI International Congress of Neuropathology is listed by the British Neuropathological Society as a future congress taking place from 19-23 September 2027 at the Edinburgh International Conference Centre. The BNS event page is currently a save-the-date notice and links to the official ICN 2027 microsite. The microsite is also early-stage: it invites delegates to register interest and says updates will cover key dates, early-bird registration and the scientific programme as these evolve. No detailed scientific programme, named speakers, abstract call, abstract deadline, presentation formats, registration fee table, registration deadline, CPD accreditation or publication outcome is published yet. This should therefore be treated as an early draft listing rather than a complete conference page. It is still in scope for MedicMess because it is an international multi-day neuropathology congress at a major UK conference venue, with likely relevance for neuropathology trainees, academic pathology trainees and clinicians with nervous-system pathology interests. The practical next step for readers is to use the official ICN interest site for updates and revisit when the abstract and registration pages go live.
