Résumé
Mature B-cell lymphoproliferation with hairy lymphocytes include Marginal Zone Splenic Lymphoma (SMZL), Hairy Cell Leukemia (HCL), Splenic Diffuse Red Pulp Lymphoma (SDRPL), and Variant Hairy Cell Leukemia (HCL-v), the two latter being provisional entities that appeared in the 2008 WHO classification. We report the case of a 75-year-old man who benefited from a diagnostic re-evaluation of his SMZL. The good clinical evolution, the flow cytometry investigation (HCL score < 3, SDRPL score > 3, strong CD180 and CD200/CD180 ratio < 0.5) and the histological assessment favored a SDRPL. This entity did not exist at the time of the diagnosis in 2006. The differential diagnosis between these diseases sometimes remains uneasy. Here are mentioned some practical clues to assess the diagnosis.
