#2: WHO Class Urinary Tumors, 40. 2004

Question:

Histology (Pre-2007)--Kidney: How is a "mucinous tubular and spindle cell carcinoma" coded? See Discussion.

Discussion:

Literature search results: "The new WHO-classification of renal tumors includes new subtypes, one of which is the mucinous, tubular, and spindle cell carcinoma. Many of these tumors had been previously diagnosed as sarcomatoid carcinoma. There are areas of cord-like growth and spindle cell configuration, sometimes with a clear cell appearance."

Answer:

For tumors diagnosed prior to 2007:

Code histology to 8255 [Adenocarcinoma with mixed subtypes]. ICD-O-3 does not have a code specific to this combination histology. 8255 is the best code available.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
