The book covers all relevant topics of uropathology (tumoral and non-tumoral), from the normal histology of the genitourinary tract to pathological findings of diseases in the male genital and urinary tract. To make the content more accessible, all content is arranged alphabetically and each entry is uniformly structured, presenting the epidemiology, the clinical signs, the gross and histological features, the immunohistochemical stainings, and the molecular data for each disease. Histological pictures clarify the microscopic findings and help readers understand the differential diagnosis for genitourinary tract diseases. In addition to internationally respected experts on pathologies of the prostate, bladder, kidney and testis, researchers coming from other disciplines such as molecular biologists, soft tissue pathologists, dermatopathologists, hematopathologists and gynaecopathologists have contributed to this book, thus making it interesting for uropathologists, but also for students, residents, clinicians (surgeons, radiotherapists, oncologists, urologists, dermatologists) and researchers who deal with disciplines that call for knowledge of the pathologies of the male genital and urinary tracts.
