Rare Hematological Diseases - Disease Groups
As a result of the revision and discussion of the RHD-DGs during the Board of the Network meeting (13-14 November 2019, Barcelona), a total of 70 RHD-DG has been identified. The Lymphoid malignancies subnetwork includes 19 disease groups encompassing 98 disorders.
RHD-DGs and disorders included are currently under revision for final approval.
