The Cutaneous Lymphoid Proliferations

A complete reference to the latest understanding of lymphocytic infiltrates The Cutaneous Lymphoid Proliferations provides a complete, authoritative treatment of the clinical features, phenotypes, pathogenesis, histopathology, diagnosis, and treatment of lymphocytic infiltrates of the skin. Incorporating the latest findings from the fields of light microscopy, immunohistochemistry, and flow cytometry, the book brings readers up to date on the most current thinking in the field. Those readers familiar with the authors′ critically acclaimed The Melanocytic Proliferations will find a similar structure and the same attention to detail and quality in this latest reference. The book starts off with a clinical atlas and introduction to the ontogeny and biology of the lymphoid system. Next, the authors explore novel molecular approaches to the diagnosis of cutaneous lymphoid proliferations and benign lymphocytic infiltrates. The remaining chapters concentrate on major inflammatory skin diseases and lymphoproliferative disorders, including chronic lymphocytic leukemia, lupus, adult T cell leukemia, and primary cutaneous Hodgkin′s disease. As a reference to lymphocytic infiltrates, this book is unsurpassed. Novice and experienced practitioners alike will gain important insights into the field, including: The role of the immune system in the pathogenesis of cutaneous disease Relationships between therapeutic drugs and cutaneous eruptions Important drug reactions Hundreds of full–color, high–quality clinical and histologic photographs help readers visualize the various infiltrates and their treatments. Having this reference on hand is essential for all dermatologists, dermatopathologists, oncologists, and general pathologists who need a synthesis of the current thinking in the field.
