Since the last edition of the Tumors of Prostate Gland, Seminal Vesicles, Penis, and Scrotum, there have been numerous significant developments in the diagnosis and treatment of prostate and penile cancers. The new Fifth Series Fascicle of the AFIP Atlas of Tumor and Non-tumor Pathology includes these developments as well as abundant images and diagrams to depict the morphological spectrum of disease entities. In this richly illustrated atlas, the authors emphasize the gross and light microscopic diagnosis and differential diagnosis, present immunohistochemistry and molecular pathology studies that are of current value in diagnosis, and discuss pathological diagnosis in terms of prognosis and treatment.
