Cutaneous T-cell lymphomas (CTCLs) are clinically heterogeneous T-cell lymphomas that arise in the skin and are characterized by their clinical and pathological features. This review will focus on mycosis fungoides (MF) and Sézary syndrome (SS), which represent 60% to 80% and less than 10% of CTCL cases, respectively. While most patients with MF present with patches and plaques and can be successfully treated with skin-directed therapies, a minority of patients progress from early to advanced stages or undergo large cell transformation. SS is defined as erythroderma, lymphadenopathy, and more than 1000 circulating atypical T-cells/uL with cerebriform nuclei. It has a poor overall survival of 2.5 years. Given the overall rarity of CTCLs, it is notable that clinical trials of treatments for MF/SS have been successfully completed, resulting in FDA approvals of novel therapies with increasing overall response rates. This review outlines the current multidisciplinary approach to diagnosing and treating MF/SS, with a focus on combining skin-directed therapies with emerging targeted and investigational systemic therapies. Integrating these anticancer therapies with skin care and bacterial decolonization is critical for comprehensive management. Curing patients with MF/SS may be possible by using a personalized medicine approach including novel combination strategies, restoration of T helper 1 cytokines, and avoidance of immunosuppressive regimens.
