Papillary renal cell carcinoma (PRCC) is a malignant, heterogeneous tumor originating from renal tubular epithelial cells of the kidney, which comprises approximately 10-15% of all kidney neoplasms. [1] Based on its morphological features, PRCC can be classified into two main subtypes, which are type 1 and type 2 (eosinophilic). [2]
The most frequent, malignant, primary kidney cancer is renal cell carcinoma (RCC) - which has several subtypes: Clear cell RCC, an epithelial cell tumour of the kidney that accounts for 65-70% of all RCCs. [5] Papillary RCC, a renal tumour that accounts for 10-15% of all RCCs. Males are 1.5 times as likely to develop this type of tumour than ...
Papillary Renal Cell Carcinoma (PRCC) Type 1 PRCC consist of papillae covered with a single or double layer of small cuboid cells with scanty cytoplasm and Type 2 PRCC consist of papillae covered by large eosinophilic cells arranged in an irregular or pseudostratified manner. 10–15%
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.

Specialty: Oncology nephrology Urology: Symptoms: Blood in the urine, lump in the abdomen, back pain [1] [2] [3] Usual onset: After the age of 45 [4] Types: Renal cell carcinoma (RCC), transitional cell carcinoma (TCC), Wilms ...
Brunelli et al. stated that genetic analysis of chromosome 7, 17, and Y may facilitate discrimination of MA from papillary renal cell carcinoma in difficult cases. Their study showed that MA lacks the frequent gain of chromosomes 7 and 17 and losses of the Y chromosome that are typical of papillary renal cell neoplasms, suggesting that MA is not related to renal cell carcinoma and papillary ...
Psammoma bodies are commonly seen in certain tumors such as: Papillary thyroid carcinoma [2]; Papillary renal cell carcinoma [3]; Ovarian papillary serous cystadenoma and cystadenocarcinoma [4]
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]
