Overview
On gross pathology, large, unilateral, multiloculated, and well-encapsulated cystic tumor is the characteristic finding of cystic nephroma. On microscopic histopathological analysis, cysts lined by a simple epithelium with a hobnail morphology and ovarian-like stroma are characteristic findings of cystic nephroma.
Gross Pathology
Characteristic findings of cystic nephroma on gross pathology include:
Microscopic Pathology
The characteristics of cystic nephromas include:
- 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
- Spindle cell morphology
- Basophilic cytoplasm

Genetics
- DICER1 is a human gene.[3] This gene encodes a protein possessing an RNA helicase motif containing a DEXH box in its amino terminus and an RNA motif in the carboxy terminus. The encoded protein functions as a ribonuclease and is required by the RNA interference and small temporal RNA (stRNA) pathways to produce the active small RNA component that represses gene expression. Two transcript variants encoding the same protein have been identified for this gene.[3]
