Renal oncocytosis is the presence of multiple oncocytic lesions within the kidney.[1]
General
- Rare.
- May be seen in the context of Birt–Hogg–Dubé syndrome or chronic renal failure or may be sporadic.[1]
- Chronic renal failure seen in 50% of cases in one series.[2]
Gross
- Multiple (unilateral or bilateral) brown-coloured nodules.[1]
Microscopic
Features:
- Any mixture of oncocytic tumours (hybrid tumour, chromophobe renal cell carcinoma, renal oncocytoma).
- "In situ" oncocytic cells (similar to the tumour cells) within renal tubules.[3]
DDx:
- Hybrid tumour.
- Chromophobe renal cell carcinoma.
- Renal oncocytoma.
- Other renal tumours with eosinophilic cytoplasm.
Images
IHC
- Characteristic of the histologic appearance.[1]
- Stain like renal oncocytomas, chromophobe renal cell carcinomas and hybrid tumours.
Molecular
- Scant data suggests chromosomal changes are seen that are different than those of ChRCC and oncocytoma.[4]
- Do not have the chromosomal losses typical of ChRCC.
- May have gains in chromosome 5.
Note:
- ChRCC typically has loss of chromosomes: 1, 2, 6, 10, 13, 17, 21.[5]
