Primary cutaneous follicle centre lymphoma with secondary systemic evolution

Abstract

Abstract Primary cutaneous follicle centre lymphomas (PCFCLs) are cutaneous proliferation of centrocytes and centroblasts, with a generally indolent evolution. Secondary systemic spread of disease is a rare event, which significantly impairs prognosis. Recently published study by Zhou and al. proposed criteria aiming to predict such evolution at initial stage: (i) rearrangement of Bcl2, (ii) Ki67% index 30% Ki67% indexes and no mutations among the four proposed genes. These findings run contrary to these previously proposed criteria, highlighting the molecular heterogeneity of this rare disease.
