Book excerpt: Written expressly for the surgical pathologist, the pathology resi-dent and the urologic surgeon, this volume describes the histopathologic appearances of diseases affecting the prostate and the seminal vesicles. The introductory chapter includes a dis-cussion on the role and limitations of immunohistochemistry and fine needle aspiration in the diagnosis of prostatic carcinoma. In the pathologic descriptions the main emphasis is placed on microscopic differential diagnosis. Many conditions are discussed including pro-static calculi, benign nodular hyperplasia, tumors of prostatic urethra, therapy-induced changes, and rare carcinomas. Many dia-grams, charts, tables and 221 photomicrographs complement the text.
