Inquiry Details
References:
WHO Class Urinary Tumors, 12, 33. 4th ed.
Question:
MP/H Ruels/Histology--Kidney/renal pelvis: How is MiT family translocation renal cell carcinoma (RCC) with Xp11 translocation coded? See Discussion.
Discussion:
Pathology states: Translocation renal cell carcinoma. Comment Tumor morphology and IHC profile consistent with MiT family translocation RCC with Xp11 translocation.
Answer:
Assign 8312/3 to MiT family translocation renal cell carcinoma (RCC) with Xp11 translocation.
The recent WHO 4th Ed Tumors of the Urinary System has proposed a new ICD-O-3 code for MiT family translocation RCC, however the implementation of this new code has not yet been approved by the standard setters (SEER, CoC, CDC, NAACCR). Until it is approved, code histology to renal cell carcinoma (8312/3).
