Σύνοψη	A multicenter case report is a structured clinical document describing one or a very small number of unusual patients observed across two or more independent healthcare institutions. By pooling observations from multiple sites, it overcomes the rarity barrier that prevents any single center from documenting an unusual presentation, adverse event, or novel treatment response — producing a richer, more externally valid account than a single-center report can offer.	A case series is a descriptive observational study that documents the characteristics, clinical course, and outcomes of a group of patients who share a common condition, exposure, or intervention. Unlike case reports, which focus on a single patient, a case series aggregates data across multiple patients (typically three or more) to identify patterns, generate hypotheses, and characterize rare or novel conditions — without a concurrent control group.
