ORPHA:544Clinical group
Also called DLBCL
What it is
Diffuse large B-cell lymphoma is the most common subtype of non-Hodgkin lymphoma (NHL) in adults characterized by a median age of presentation in the sixth decade of life (but also rarely occurring in adolescents and children) with the initial presentation being single or multiple rapidly growing masses (that may or may not be painful) in nodal or extranodal sites (such as thyroid, skin, breast, gastrointestinal tract, testes, bone, or brain) and that can be accompanied by symptoms of fever, night sweats and weight loss. DLBCL has an aggressive disease course, with the elderly having a poorer prognosis than younger patients, and with relapses being common.

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.
Genes reported in subtypes
Orphanet records these genes on 3 more specific entries under this disorder, not on this entry itself:
A well-studied disease is usually split into subtypes, and the gene is curated on whichever one the evidence belongs to. Open a subtype to see which gene goes with it.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
Related health topics
Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
