Multilocular Renal Cyst. Report of Two Cases and Review of the Literature

Multilocular renal cyst (MRC), or cystic nephroma (CN), is a rare tumour of the kidney. Approximately one hundred cases have been reported, half of these in children. Normally these lesions have been confirmed to be benign cystic lesions, but it is possible for them to transform into malignancy. In children this type of tumour may simulate Wilms' tumour. We report two cases of MRC disease with clinical findings, pathology, treatment and survival.
