CYSTIC NEPHROMA / MIXED EPITHELIAL STROMAL TUMOUR

Comment:
Cystic nephroma and mixed epithelial stromal tumour were described as separate entities. The WHO classification of renal neoplasia (known as the Vancouver classification) lumps them together.[1]

Cystic nephroma/mixed epithelial stromal tumour is a rather awkward name. One cheeky article suggests the term renal epithelial and stromal tumour (abbreviated REST) to put the issue to rest.[2]
