title: BRAF V600E-Negative Hairy Cell Leukaemia.
abstract: Since the initial report of the BRAF V600E mutation in hairy cell leukemia, numerous investigators have demonstrated the presence of this activating mutation in nearly all cases of this disease. A case of hairy cell leukemia is documented with a classical clinical, morphological, immunophenotypic, and cytochemical profile in which the BRAF V600E was not detected. The diagnostic and therapeutic implications are discussed.
