Primary cutaneous lymphomas (PCLs) are a heterogeneous group of lymphoid tumors that originate primarily in the skin. Most PCLs (75%) are T-cell lymphomas and only 20% to 25% involve B cells. It is important to differentiate between cutaneous lymphomas and lymph node tumors given the differences in their molecular biology and clinical, histopathologic, and immunophenotypic features. Moreover, PCLs generally follow a more indolent course and require different treatments. Many treatment options are available for managing PLC's. The choice should be based primarily on the clinical stage of disease but must also take into consideration other factors, such as the patient's age and general health, the availability and accessibility of the treatment, and the cost-benefit ratio. It will be important to use a multidisciplinary approach, involving a team of expert dermatologists, hematologist-oncologists, and radiotherapists who are familiar with this rare disease. Recent years have seen the emergence of many new therapies, particularly for advanced stages of the disease and for patients whose tumors have proven refractory to treatment. The objective of this article is to review all the treatment options available to us.

This article reviews the history of cutaneous lymphomas through the articles published on this subject in the journal Actas Dermo-Sifiliograficas. Approximately 100 years after Alibert published the first description of a patient with mycosis fungoides in 1806, reports of cutaneous lymphoma cases began to appear in Actas. These articles reflect how the definition, classification, and treatment of this disease, which continues to pose a challenge for dermatology, have evolved over the 100-year lifespan of the journal.
