A cystic nephroma, also known as multilocular cystic nephroma, mixed epithelial stromal tumour (MEST) and renal epithelial stromal tumour (REST), is a type of rare benign kidney tumour.
The characteristics of cystic nephromas are:
- Cysts lined by a simple epithelium with a hobnail morphology, i.e. the nuclei of the cyst lining epithelium bulges into the lumen of the cysts,
- Ovarian-like stroma that has a:
Cystic nephromas have an immunostaining pattern like ovarian stroma; they are positive for:
