Abstract:
Collecting duct carcinoma (CDC) is a rare renal malignancy thought to develop from the collecting duct epithelium of the kidney. CDC tends to have a more aggressive clinical course than conventional renal cell carcinoma (RCC), with early metastases. The occurrence of a mixed CDC and conventional RCC is infrequently reported in the literature. We report the first case of a metastatic mixed CDC and RCC presenting as back pain in a young adult. In addition we discuss the epidemiology of and current adjuvant therapies for CDC.

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...
