Publication date: 18 Jan, 2016

Consensus grade: oncocytoma

User Diagnosis Difficulty Comment
Pathologist 1 oncocytoma Typical
Pathologist 2 Insufficient tumor for diagnosis Not typical

Could be oncocytoma or RCC, unclassified....low-grade oncocytic type! The gross image is not of much use or specific!

Pathologist 3 oncocytoma Typical

nice combination of gross photo and histology

Pathologist 4 Renal cell carcinoma, unclassified Typical

Oncocytoma vs eosinophilic variant of chromophobe

Pathologist 5 Chromophobe RCC Typical
Pathologist 6 oncocytoma Typical
Pathologist 7 Other Not typical

It would be foolish to make a definitive diagnosis of oncocytoma on only this image even with the gross. Add a low and intermediate power magnification and this would be a great case.
