Papillary renal cell carcinoma (RCC), defined histologically as a malignant epithelial tumor of the kidney with a minimum of 50% papillary architecture 1 and, more recently, by a combination of histologic and cytogenetic features, 2 represents between 7% and 15% of renal carcinomas.

Click, Type 1 (basophilic) papillary renal cell carcinoma, Type 1 (basophilic) papillary renal cell carcinoma (pRCC), Type 1 vs type 2 described in 1997 by Delahunt and Elbe (, Composed of small cuboidal cells with scant pale cytoplasm arranged on single layer of papillary cores, tubules and glomeruloid structures, Often contains foamy macrophages and psammoma bodies, Gains in chromosomes 3, 7 and 17 ( > 80%), Less locally advanced disease and lower rates of metastasis than type 2 pRCC (, In one series of papillary RCCs, ~25% had classical type 1 features, ~25% were type 2 and ~50% had some degree of overlapping features (, Stage for stage, better prognosis and survival times than Type 2 pRCC (, 12 year old boy with a horseshoe kidney (, 63 year old Caucasian man with synchronous colorectal cancer and papillary RCC (, 75 year old man with papillary RCC within a renal oncocytoma (, Receptor tyrosine kinase inhibitors including sunitinib and sorafenib, Nivolumab, cabozantinib and lenvatinib plus everolimus, Often well circumscribed with thick capsule, Friable with patchy appearance (yellow, grey, brown) and frequent hemorrhage, Small cuboidal cells arranged on single layer on papillary cores (, Cells are small with uniform, scant pale cytoplasm and round, hyperchromatic nuclei without nucleoli, Papillary cores often contain foamy macrophages. Am J Clin Pathol. Papillary Renal Cell Carcinoma, Spindle type. Critical/controversial points in staging of RCC include: pT3a is defined as extension into perirenal fat, This requires actual touching of fat, preferably infiltration into and between fat cells, It does not include bulging tumor with stretched, thin capsule that appears to touch fat, Classically has been considered fat peripheral to the cortical capsule, It appears that renal sinus (peripelvic) fat should be considered equivalent, The renal sinus must be examined grossly and appropriately sampled, pT3 requires gross involvement of renal vein and or vena cava, This requires an adequate gross examination, Retraction of vascular wall around a lumenal tumor thrombus may falsely suggest a positive margin, Positive vascular margin requires involvement of the vessel wall at the margin, Direct (contiguous) invasion of the adrenal gland (pT4) should be distinguished from discontiguous (metastatic) involvement (pM1), Type 2 has worse overall prognosis than Type 1, When controlled for stage and grade, behavior is similar, Murphy WM, Grignon DJ, Perlman EJ.

Clear cell papillary renal cell carcinoma (ccpRCC) was introduced as a new tumor entity by the 2016 World Health Organization (WHO) classification of renal neoplasia because of its unique morphologic, immunohistochemical, and genetic features, and its indolent clinical behavior. 1–4 It was initially described in 2006 in conjunction with end-stage renal disease. It is the second most common type of kidney cancer in adults. Among renal cell neoplasms, the term adenoma is reserved for those with a papillary or tubular pattern. 2006 Jan;30(1):13-9. J Urol.
