- 3 Downloads
This tumor was previously named “multilocular cystic renal cell carcinoma.”
Multicystic tumor with septa containing individual or groups of clear cells with ISUP/WHO 2016 low nucleolar grade (1–2).
This tumor accounts for less than 1% of all renal tumors, usually incidentally discovered.
It occurs in middle-age adults.
There is no difference between male and female.
There is no site predilection.
Partial or radical nephrectomy is the surgical treatment of choice.
