Generally, the cells have a clear cytoplasm, are surrounded by a distinct cell membrane and contain round and uniform nuclei. [citation needed] Microscopically, CCRCCs are graded by the ISUP/WHO as follows: [1] [2] Grade 1: Inconspicuous and basophilic nucleoli at magnification of 400 times
Papillary renal cell carcinoma type 1, grade 2: Nucleoli (one annotated by arrows) are conspicuous and eosinophilic at 400 magnification and visible but not prominent at 100 magnification. The WHO/ISUP system is histological tumor grading system for renal cell carcinoma, suggested by the International Society of Urologic Pathologists (ISUP) in ...
Clear cell papillary renal cell carcinoma (CCPRCC) is a rare subtype of renal cell carcinoma (RCC) that has microscopic morphologic features of papillary renal cell carcinoma and clear cell renal cell carcinoma, yet is pathologically distinct based on molecular changes and immunohistochemistry. [1]
Metastatic renal cell carcinoma (mRCC) is the spread of the primary renal cell carcinoma from the kidney to other organs. Approximately 25–30% of people have this metastatic spread by the time they are diagnosed with renal cell carcinoma. [ 101 ]

The renal cell carcinoma tends to be of the papillary (type 2) form and tends to occur more commonly in women than men with this syndrome. These cancers present earlier than is usual for renal cell carcinomas (typically in the twenties and thirties) and tend to be at relatively advanced stages at presentation.
Carcinoma is a malignancy that develops from epithelial cells. [1] Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal [2] or ectodermal germ layer during embryogenesis.
Collecting duct carcinoma in computed tomography. Collecting duct carcinoma (CDC) is a type of kidney cancer that originates in the papillary duct of the kidney. It is rare, accounting for 1-3% of all kidney cancers. [2] It is also recently described; a 2002 review found just 40 case reports worldwide. [3]
