Abstract:
The detection of primary tumors synchronous with colorectal cancer has been the subject of multiple publications. This association can occur sporadically or fall under the framework of well defined clinical syndromes such as Lynch syndrome. Synchronous association of colorectal cancer (CRC) and renal cell carcinoma is rare. It is even more rare when renal cell carcinoma is of papillary origin, with only 2 cases reported in the literature. The association between CRC and renal cell carcinoma does not seem to be related to mismatch repair proteins (MMR) abnormality and does not include, up to now, any clinical syndrome. We report the case of a 69-year old woman with colorectal cancer associated with synchronous type 1 papillary renal cell carcinoma unexpectedly detected during screening for CRC. We here discuss the pathogenesis as well as the prognosis of this rarely described entity.

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...
Renal Tubule and Collecting Duct
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...
The Retinoblastoma Gene
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,...
