Renal Oncocytoma
Description
Oncocytoma is a benign renal epithelial neoplasm and accounts for 5% of the tumors derived from tubular epithelium. [1][2]
IHC Markers
Positive: CD10, E-cadherin, EMA, PAX2, PAX8, CD117, AMACR.
Negative: vimentin, CD10, RCC, CK7.
Genomic Gain/Loss/LOH[3]
| Chromosome | Gain/Loss/Amp | Region |
|---|---|---|
| 1 | Loss | Chr1 |
| 14 | Loss | Chr14 |
| 21 | Loss | Chr21 |
| X | Loss | ChrX |
| Y | Loss | ChrY (male) |
Rearrangements

mtDNA
COX1, COX2, COX3, ND4, ND5, CYTB
Epigenomics (methylation)
Unknown
Main Pathways Involved
Mitochrondrial electron transport chain, autophagy and golgi trafficking.[2]
Diagnosis
Diploid with CCND1 rearrangement (Type I); Loss of 1, 14, 21, X or Y (Type II)[2]
Prognosis
Type II is more aggressive and may progress to malignant eosinophillic chrRCC.
Familial Forms
Birt-Hogg-Dube syndrome (BHD): FLCN (17p11.2)
