Primary cutaneous T-cell lymphomas (PCLs) mycosis fungoides (MF) and Sézary syndrome (Ss) belong to the group of non-Hodgkin lymphomas (NHL), which are characterized by clonally proliferating CD4+ cells localized in the skin. Although there already exist many conventional skin-directed and systemic cytotoxic treatment options, in long-term only a transient remission without curative results will be reached in most cases. The aim of this article was to present actual assumed treatment modalities, as well as new therapeutic strategies which passed already through clinical trials showing promising results in the treatment of PCLs.

Background: Mycosis fungoides (MF) represents the most common type of primary cutaneous T cell-lymphomas (CTCL), which are characterized by a clonally proliferation of malignant CD4+ lymphocytes in the skin., Objective: Skin-directed treatment regimens, like phototherapy and corticosteroids, are commonly used in early stages; systemic treatments and chemotherapies are used in advanced stages. Because conventional treatments usually end in a transient remission without curative results, there is a high need for new therapeutic strategies with acceptable side effects., Methods: Literature and reference research was done by using the data bank PubMed, and updates of ongoing studies were taken out of ASCO and ASH annual meeting abstracts., Results/conclusions: This article gives an overview of the various medications in current use, with emphasis on emerging drugs with novel therapeutic targets.
