摘要

Cutaneous T cell lymphomas (CTCL) are non-Hodgkin T cell malignancies defined by malignant T cell transformation and accumulation in the skin. Limited understanding of CTCL pathogenesis, including the role of the tumor microenvironment, hinders effective treatment. Emerging evidence implicates the skin microbiota as a key modulator of disease, with microbial dysbiosis contributing to progression and representing a novel therapeutic target. This review synthesizes findings from 37 rigorously selected studies, outlining current knowledge of the CTCL-associated microbiome, mycobiome, and virome. It evaluates therapeutic strategies aimed at microbial colonization, emphasizing the potential of modulating host–microbe interactions. Additionally, we provide comprehensive clinical insight into the indications for microbial-modulating strategies of the microbiota in CTCL.
