Benign cortical cyst of the kidney is an extremely common benign kidney finding.
Benign renal cyst redirects here. A more general discussion about cysts in the kidney is in the article cystic kidney diseases.
General
- Very common.
- Benign.
Gross
- Thin-walled cyst - usually filled with serous fluid.
- Usually unilocular.
Microscopic
Features:
- Simple epithelial lining without atypia.
- May have clear cells.
Note:
- Do not have clear cells within the wall of the cyst.[1]
DDx:
- Localized cystic disease of the kidney.
- Cystic neoplasms/renal cell carcinoma:
- Cystic clear cell renal cell carcinoma - thick septa with clear cells.
- Multicystic renal cell neoplasm of low malignant potential - thin septa, clear cells within stroma.
- Other cystic kidney diseases.
