title: Nuclear morphometry in differential diagnosis of renal oncocytoma and renal cell carcinoma.
abstract: OBJECTIVE
  Morphometric distinction of renal oncocytoma and renal cell carcinoma was attempted.
  
  
  METHODS
  Nuclear morphometric measurements were done from sections of 16 histologically diagnosed renal oncocytomas and renal cell carcinoma controls (grade 1 or 2, stage T1 to 2N0M0).
  
  
  RESULTS
  Oncocytomas could be distinguished from carcinomas on the basis of nuclear morphometry in more than 80% of the cases. Especially, the shape descriptors (form factors) were significantly different between oncocytomas and carcinomas.
  
  
  CONCLUSIONS
  Morphometrically determined nuclear shape descriptors can be used to support diagnostic decisions in problematic cases.
