This book provides practicing urologists and diagnostic surgical pathologists (and physicians in training) with immediately useful information in their patients' care. This is intended to bridge the gap between pathologists and urologists by providing mutually important updated information. In the format of Question/Answer (Q/A), Professor Oyasu answers a number of questions from practicing and academic urologists, while reviewing the leading pathology and urology journals worldwide and extracting the updated information. This book covers many issues for the clinician in regard to the pathology of tumors of the adrenal, kidney, urothelium, prostate and testes. This book is designed to be easy to use. Each question is followed by a succinct answer and comments supported by references with generous use of full color photographs/illustrations.
