Although this second edition retains the concise format of the first edition, the number of tumours described has increased considerably, especially in the melanocytic, adnexal, fibrous tissue and lymphoid neoplasms. Care has been taken to avoid needless subclassification, so as to limit the expansion of categories to those fulfilling demonstrable histological criteria. The commentaries remain succint whilst including the major diagnostic points, with reference to relevant immunohistochemical features. All the illustrations have been changed since the first edition. Of particular importance is the fact that close collaboration with the authors of the AFIP Atlas of Tumor Pathology on Melanocytic and Non-melanocytic Tumors of the Skin ensures a consistent approach to the classification.
