Abstract
SummaryFor a disease initially described in 1958 as a leukaemic reticulo‐endotheliosis associated with poor outcomes, we have come a long way in our understanding of Hairy cell leukaemia. The vast majority of patients diagnosed with this rare, often diagnostically challenging, leukaemia can now expect a lifespan that is similar to the general population. This article covers some of the highlights from the last 6 decades that have led to our current understanding of this fascinating leukaemia ‐ from elucidation of its B‐cell origin to discovery of the almost universal occurrence of the BRAF V600E mutation; from the initial successes reported with splenectomy to the more recent development of targeted therapies such as Vemurafenib and Moxetumomab Pasudotox. It also pays tribute to some of the outstanding research in this field focusing particularly on the significant contributions made by the clinical and scientific community in the UK.
