This book provides a comprehensive, state-of-the-art account of the role of immunohistochemistry in the diagnosis of skin tumors, which is crucial given that overlapping histologic features and unusual morphologic changes can lead to considerable diagnostic uncertainty. The book reviews in detail the sensitivity and specificity of commonly available antibodies and their pattern of immunostaining. readers will learn when to order antibodies and how to interpret findings. In addition, prognostic markers are evaluated and emphasis placed on the pitfalls commonly encountered when evaluating these neoplasms. The text is complemented by a wealth of superb images. Helpful histograms and algorithms are included, and clear guidance is provided on the application and interpretation of less commonly used antibodies and immunostains. Applied Immunohistochemistry in the Evaluation of Skin Neoplasms will serve as an extremely valuable resource for practicing dermatopathologists and pathologists.
