This edition represents a significant expansion of both the textual and illustrative material of the previous volume. The numerous images reflect the authors' belief that the atlas role that was the intent of the original edition is of paramount importance in this work. At the same time, the current scope is no longer primarily that of a visual resource, but also a comprehensive guide to clinical, pathologic, immunohistochemical, molecular biologic, prognostic, and to a limited extent, therapeutic aspects of the various entities. For this reason, the authors have greatly expanded coverage of the immunohistochemical and molecular features of the various lesions, recognising that such information is quickly supplemented by new observations. Nonetheless, they continue to believe that careful gross examination and routine light microscopic observations are the foundations for diagnosis of these neoplasms and neoplastic-like processes.

A complement to Tumors of the Prostate Gland, Seminal Vesicles, Penis, and Scrotum, this volume will serve as an outstanding resource for the diagnosis of testicular neoplasms for pathologists at all levels of experience.
