cystic partially differentiated nephroblastoma

Friday 24 February 2006

Definition: Cystic partially differentiated nephroblastoma is a relatively rare tumour of the kidney usually affecting infants. Cystic partially differentiated nephroblastoma may undergo local recurrence but there is no report of metastasis.


- Cystic partially differentiated nephroblastoma


- hyperdiploidy
- trisomy 12

Differential diagnosis

- cystic Wilms tumor (WT)
- cystic nephroma (CN)

Cystic Wilms tumor and multilocular cystic nephroma should be distinguished from cystic partially differentiated nephroblastoma.

Multilocular cystic nephroma is a benign tumor whereas cystic Wilms tumor is at the malignant end of the range of classification of such tumors.
