'''Multilocular cystic renal cell carcinoma''', abbreviated '''MCRCC''', is a rare [[kidney tumour]].
'''Multilocular cystic renal neoplasm of low malignant potential''' is a rare [[kidney tumour]].

As the behaviour of the tumour is very good, it has be proposed that this entity be renamed '''multilocular cystic renal cell neoplasm of low malignant potential'''.<ref name=pmid23893851>{{Cite journal  | last1 = Montironi | first1 = R. | last2 = Mazzucchelli | first2 = R. | last3 = Scarpelli | first3 = M. | last4 = Lopez-Beltran | first4 = A. | last5 = Cheng | first5 = L. | title = Update on selected renal cell tumors with clear cell features.

Kidney Mass, Right, Partial Nephrectomy:
    - Multilocular cystic renal neoplasm of low malignant potential, see comment and microscopic.
Comment:
This lesion is generally believed to have a benign behaviour.
</pre>
===Micro===
The cyst lining cells are clear and eosinophilic and without prominent nucleoli. Cyst lining cells do not infiltrate the cyst wall. Benign remnants of renal parenchyma are not evident throughout the cyst walls. This lesion is both within the kidney and perinephric fat.
