PATHOLOGICAL ANATOMIC MANIFESTATIONS AND CLASSIFICATION OF ONCOLOGICAL KIDNEY DISEASES

Abstract

Kidney cancer is particularly important because it creates a big economic burden, especially when it spread (metastatic kidney cancer). Kidney cancer primarily arises from the renal parenchyma, with clear cell renal cell carcinoma being the most common type, derived from the renal tubular epithelium, and comprising roughly 70% of cases in adults. The majority of epidemiological research tends to concentrate on kidney cancer as a whole entity, leading to a scarcity of detailed information about the various histological subtypes. Less common are tumors originating from the renal pelvis a form in the center of the kidney where urine collects, and Wilms tumors in children that typically develops before the age of five, which are significantly rarer than renal cell carcinomas and display different epidemiologic patterns.
