'''Unclassified renal cell carcinoma''', abbreviated '''URCC''', is an epithelial malignant tumour arising from the kidney parenchyma, i.e. a [[renal cell carcinoma]], that cannot be further classified. | |||
==General== | |||
*Uncommon. | |||
*A [[WHO]] classification ''diagnosis of exclusion''. | |||
*Worse prognosis than [[clear cell renal cell carcinoma]].<ref name=pmid17822461>{{Cite journal | last1 = Karakiewicz | first1 = PI. | last2 = Hutterer | first2 = GC. | last3 = Trinh | first3 = QD. | last4 = Pantuck | first4 = AJ. | last5 = Klatte | first5 = T. | last6 = Lam | first6 = JS. | last7 = Guille | first7 = F. | last8 = de La Taille | first8 = A. | last9 = Novara | first9 = G. | title = Unclassified renal cell carcinoma: an analysis of 85 cases. | journal = BJU Int | volume = 100 | issue = 4 | pages = 802-8 | month = Oct | year = 2007 | doi = 10.1111/j.1464-410X.2007.07148.x | PMID = 17822461 }}</ref> | |||
*High variation in the prevalence (when comparing institutions); this suggests a lack of uniformity in the diagnosis of this subtype.<ref name=pmid17822461/> | |||

*#A combination of other RCC histologic types (~35% of cases of URCC). | |||
*#Has a "non-identifiable" pattern/unrecognizable cell type (~60% of cases of URCC). | |||
*#Pure [[sarcomatoid RCC]] without an identifiable (epithelioid) RCC subtype (~5% of cases of URCC).<ref name=pmid22404824/> | |||
