Cutaneous Lymphomas

Knowledge of cutaneous lymphomas has been growing significantly as a result of important discoveries in immunology, molecular biology, and immunohistochemistry. Improved clinical pathologic correlation and follow-up data, as well as the synergistic collaboration among different lymphoma registries and specialists from several academic medical centers have greatly contributed to the understanding of the difficult field of cutaneous lymphoproliferative disorders. While these advances have increased understanding of skin lymphomas, they have also produced an extensive and sometimes confusing litany of articles, studies, and classification schemes. This issue on Cutaneous Lymphomas in Surgical Pathology Clinics provides an organized and updated review of this challenging topic by leading experts. It bridges critical knowledge gaps in the diagnosis of cutaneous lymphomas. Sezary Syndrome, Mycosis Fungoides and variants are presented along with B-cell, CD30, lymphoproliferative disorders among others. In addition to multiple clinical and microscopic images, tables and algorithms are presented to aid in diagnosis and staging. Beyond its usefulness to general pathologists, dermatopathologists, and hematopathologists, this information is intended to be helpful for dermatologists, hematologists/oncologists, fellows, and residents.
