Rare Tumors is an international peerreviewed medical journal established in 2009. The journal is focused on rare cancers and aims to expand upon current knowledge on their presentation, diagnosis, management, and outcomes. We reviewed the 335 case reports published from 2009 to 2015. We found great diversity in both the country of origin as well as specialty of first authors. Outside of the United States (US) and European Union (EU), there were 20 countries with contributions to the journal. Similarly, there was representation from twelve medical specialties with first authorship of reports. Rare Tumors continues to encourage involvement from physicians across the globe and from all medical disciplines.
