Neuroblastoma Associated Renal Cell Carcinoma
Differential Diagnosis
- The diagnosis typically is made easily if the history of neuroblastoma is known
- Neuroblastoma associated (oncocytoid) carcinoma may be separated from conventional types of renal cell carcinoma using standard criteria
- It may be confused with translocation carcinoma because of the abundant tumor cell cytoplasm
- TFE3/B stains or molecular studies may be required
Neuroblastoma associated carcinomas are typically composed of oncocytic cells, which may pose this differential
