| A rare indolent subtype of clear cell renal carcinoma arising from epithelial cells in the renal cortex. It most frequently manifests with a well-circumscribed, well-encapsulated, unicentric, unilateral, small tumor that typically does not metastasize. Clinically it can present with flank or abdominal pain or hematuria, although most patients are usually asymptomatic at the time of diagnosis. |
