Although extranodal lymphomas are not rare, the frequency of involvement of any particular site is not high enough for a single institution to answer the major question. The mission of the IELSG is to improve the knowledge and treatment of extranodal lymphomas by bringing together numerous scientists from different institutions around the world to collect data from a sufficient number of patients to successfully study specific extranodal sites of involvement.
The long-lasting experience of the involved investigators, the strong network of collaborations with worldwide experts in lymphomas and the excellent results fuel the enthusiasm and the commitment to keep taking up new challenges with the ultimate goal of improving patients’ outcomes.
