Summary
The classification of papillary renal cell carcinoma is expanding due to new molecular and morphological data. This includes numerous new subtypes and genetic associations, highlighting the evolving nature of renal cancer diagnosis.
Area of Science:
- Renal oncology and pathology
- Molecular genetics of cancer
- Tumor classification systems
Context:
- The 2004 World Health Organization (WHO) classification of renal tumors in adults reflects advances in understanding renal cancer.
- Morphological and molecular data are crucial for defining new tumor entities.
- Ongoing discoveries in molecular genetics necessitate continuous updates to cancer classifications.
Purpose:
- To review the expanding spectrum of papillary renal cell carcinoma (PRCC).
- To highlight the heterogeneity in genetic background and phenotype within PRCC.
- To discuss newly described entities and their relationship to established PRCC categories.
Summary:
- Papillary renal cell carcinoma (PRCC) encompasses a wide and heterogeneous group of neoplasms.
- This includes conventional sporadic forms, hereditary syndromes, and specific genetic disorders.
- Distinct morphological variants and recently included entities like tubulo-cystic carcinoma further broaden the PRCC classification.
Impact:
- The classification of PRCC is progressively expanding with new, sometimes poorly defined, entities.
- Future discoveries in molecular pathology will continue to refine and enlarge the PRCC group.
- Pathologists play a critical role in identifying and integrating these new renal cancer classifications.

The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Renal Corpuscle
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...

Renal Tubule and Collecting Duct
The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...

Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
