Cutaneous T cell lymphomas (CTCL) are a diverse group of extranodal non-hodgkin's lymphomas defined by a skin infiltration of neoplastic monoclonal T cells. Adults between the ages of 55 and 60 are most commonly affected, with a yearly incidence of roughly 0.5 per 100,000. The most frequently occuring subtypes of CTCL include mycosis fungoides, Sézary syndrome, and primary cutaneous peripheral T cell lymphomas not otherwise specified (PCTCL-NOS). CTCL is a difficult disease to understand in terms of etiology, pathogenesis, diagnosis, treatment, and clinical outcome. In this paper, we give a case study and highlight the progress made in these sectors.
